Paul, your first hint with the Y-connector is interesting for me, but unfortunately this would mean either solding within current cabling or introducing an additional connector. Some could object to adding another box full of active electronics, but the same objection can be made — and dismissed — when it comes to adding a preamp to the system when the DAC or Phono stage has a level control. This connection can be made without affecting the performance of the amplifier because the sub’s amplifier input impedance is 100,000 ohms. There may be differences in the ability of different pre amps to “drive” a sub. I currently own dual JL Audio fathom subs and would have a hard time believing how much better REL is than JL Audio, honestly. Since the sub will be a system with its own individual characteristics I would have expected that the ‘cleaner’ signal from the pre-amp would be a better starting point. JLAudio has (I think), B&W not, to name only few examples of great subs. His current big project, other than playing with stereos, is writing a book series called the Carbon Chronicles. It is mandatory to procure user consent prior to running these cookies on your website. I also ask myself, how strong must those resistors be that a 500W amp can blow its signal into them. It remains on with a slight hum now. I don’t agree. 3.2 Earthing System Earthing systems shall comply with the relevant technical standards, including: • the Wiring Rules; Mains electricity is the term used to refer to the electrical supply coming from a power station to the household you live in. “High-level connection, using the enclosed cable with the Neutrik Speakon connector, is always the first choice. Indeed I read, that REL recommends high level input. The hi-level input works fine. With the m700 if you use the output to feed the high level input of the sub you connect the negative input of the sub high level input to chassis ground of the m700 and then connect the + output of the m700 to the + input of the sub. What are you planning to do? And I also fully agree to your last passage. I think the future will be along the lines of what Paradigm is doing with their Persona line in that they have DSP and room correction integrated in the speakers. Even with 50′ of wire, after the room correction setup was run, it all fires seamlessly to my ear and there is no way of ever telling the subs are at the back of the room, the low end just emits from the front of the room where the Focal speakers are. I prefer to use the second outputs from my preamp to go directly to the sub and let the main speakers run full range. another option i read is to jumper from the towers to the subs; is that wise? I never heard this from any manufacturer. Terminology. unquote. Well…yes.. In this scenario, you have one cable between the preamp and amplifier (with a Y connector at the amp’s input). Lets not forget that there are huge advantages to you using an outboard crossover, especially if your main speakers are two ways or true 3 ways. Without it, my room/system sounds muddy and boomy, no matter what I do. So don’t use one of the pre-amp outputs if you want best results. http://www.acousticfrontiers.com/devialet-subwoofer-crossover/ Like some other units, you have to put the configuration on a SD card, but you can change the card without having to turn the unit off and it reads the new card in seconds. Construction wiring (Construction and demolition wiring) means wiring systems installed to provide electrical supply for construction and demolition work, and is not intended to form part of the permanent electrical installation. lcd54222 it would be even nicer if there were two pair of balanced and single outputs like with the PCA-2. The pre and main amps are connected with U shaped metal jumpers. How much power do you need? Made by the Blue Sword team. The current flows in one direction, then the opposite, continuously. I hear it’s amazing. I guess much of the comparison is also depending on the ability of the preamp to power a second output to the sub. Replies to my comments Best possibly would be to add a socket and some soldering to the poweramp to route through the incoming signal to the sub while not compromising the incoming preamp signal to the amp. I put a solder lug under one of the screws that attaches the top cover and connected the – side of the sub high level input to that solder lug. Sigh. With that being said, I’d love to try integrating the JL crossover unit. I’ve used REL subs for many years, because this approach is built into their design. Sub mains power installation is a very difficult thing to undertake alone. On my Sumiko subs (one driven by the left and the other driven by the right channel) the sub volume controls both the RCA and speaker inputs to the sub so I would have to break the signal connection to the RCA or it would pollute the subs signal. But maybe…. It should be noted that frequencies in the sub-bass range of a delay system do not require distribution. Old tech?? At 50′ of run between the receiver and the subs, I am back to the receiver’s LFE out/in to the subs instead. The dual rcd board i am installing has a 100amp main switch but this will be fed from a 60 amp main switch at the board so as to allow for smaller cable size. Preamplifiers aren’t especially appreciative of the cables that connect them to amplifiers. I didn’t like it, always heard the subs “working” a bit (maybe it was my imagination). but suffice to say I find the sound with DSP on my Anthem AVM60 (and DSP on Fathoms also running) to be remarkable in conjunction with my B&W 804’s. Note: Wiring systems include cable enclosures, underground wiring, aerial wiring, catenary support, emergency systems, busbar trunking and earth sheath return. The second method is a good reason to get a REL subwoofer, as it comes supplied with its own high level Speakon cable designed specifically to take the signal to the main speaker outputs. it’s just old tech. Internal to the subwoofer are high-value resistors that neck-down the amp’s big output to something usable to the sub’s internal amplifier. Also Richard Vandersteen has been offering this value for decades. Shorter is better if you can manage. Years ago, there were mostly passive subs, but over time this changed. All but the smallest speakers will produce output in that range. interposing any additional electronics into the amplification chain” Isn’t it that a second pair (or single) speaker at the amps terminals vary the load for the amp? The DSpeaker from Finland is extremely popular, designed specifically for subwoofers, does DSP in the range 16-144Hz, and can take a balanced cable to the subwoofer if a long run is needed. i believe you plan to take advantage of the internal crossover of the sub, and relieve the power amp from low frequency, but i feel this will do more harm than good. Wiring systems near building surfaces - Wiring systems that are fixed in position by fasteners, or held in position by thermal insulation, or by passing through an opening in a structural member concealed within 50 mm from the surface of a wall, floor, ceiling or roof. This relaxes the load on the preamp relative to running two parallel interconnect feeds. i use stereo sealed 12′ subs and elac towers, as advised by mr. mcgowan. © 2021 PS Audio - Boulder, Colorado, USA, After labeling the subject, here's where you type in your actual question for Paul. All (I understand that home theater is another monster, and that a swarm system provides smooth bass.). What? Switchboards can be located anywhere throughout the building. It enters the house via the live wire, which carries the incoming electricity. There are many ways to integrate subs into your two channel system. Highstream, high level inputs mean speaker level inputs which would come from the amp. The difference was that the rolled off Quads could play about 3 dB louder without distress, and certainly the high-power amplifiers in common use today aren’t going to be benefited by removing the bass drive from the signal. Nothing too fancy wiring-wise so as to be affordable in that area. And we all know our hobby is the most subjective hobby in the world, as far as soundquality is concerned. I used a cheap Behringer digital parametric equalizer/RTA to this, and it worked pretty well. You could be correct about this jb4, I just like to start arguments sometimes. I notice that when I set the sub to auto (where the sub turns itself off after X minutes of non-use), the sub doesn’t turn itself off anymore. Separate crossovers are far superior sounding than their addition to the circuit might theoretically imply. There’s just something in me that thinks “what would happen if we’d overamplify a phono signal before it hit’s the preamp and then in the preamp reduce it to the proper level with some resistors”. This scheme also avoids adding any detrimental effects by not Well, I don’t know if I’m right here, I’m not an electronic engineer. If you have an immediate question email us. We don’t want to hear the subwoofer. There are other very effective methods. In fact, “room gain” allows small speakers to have fairly convincing bass, if it complements the speaker’s Low frequency rolloff, often yielding fairly flat bass response into the mid-40 Hz range. If you would like any advice about commercial and industrial mains power installations or have any other queries, contact us. The term includes: consumer mains and sub-mains supplying site switchboards The best subwoofers I ever could listen to were RiPols. It is not recommended that you carry out this yourself. But here goes. How’d I do? Necessary cookies are absolutely essential for the website to function properly. Thank you, Caution, if you need to use a subwoofer because your main system doesn’t reach the lowest audible octave or two (and most don’t) then you need to use a high pass filter to prevent overdriving them at frequencies they can’t handle or you may get harmonic distortion from them or even damage them. They would never suggest doing what I did and eschew the $100,000 speaker sale. These cookies will be stored in your browser only with your consent. This may be his greatest contribution to the audio industry in his career. Not that I ever used this method so far (didn’t know of its existence) but maybe in the future. Moreover, adding a separate power amp for the subwoofer greatly increases the system’s dynamic range and frees the main-speaker amplifier from the burden of driving the sub. You also have the option to opt-out of these cookies. Splitting an audio signal degrades it very little. I have used both regular RCA cables and also specifically labeled ones for coax and for subwoofer and failed to hear any difference. Secondly an external crossover I think usually is the best solution and this will deliver low input anyway to the sub. Every consumer-sized room has a fundamental resonance (dictated by its volume), which usually falls somewhere between 40 and 60 Hz. Putting subs in the corner is an obvious fallacy, can Dr. Toole not think in three dimensions? Well, as life would have it, a remodeling and renovation of the primary living space (which is dual use space for listening and for home theater) moved everything around and my subs now live at the back of the room, far removed from the front speakers and from the amplifier. hi captrajesh, not speaking from experience, but i feel that would unnecessarily complicate the signal path. This sub panel has 16 places for single breakers it currently had 3 double pole and 8 combo 15 & 20 breakers installed. Electrically, the main system doesn’t even know it’s there. Connect the Neutral and Live Wire from utility pole in the first two input slots of single phase energy meter respectively as shown in fig 1. if you aren’t sure that how to wire a three-phase energy meter, then check this simple tutorial which show How To Wire a Single Phase kWh meter ( Digital or analog Energy … Any cookies that may not be particularly necessary for the website to function and is used specifically to collect user personal data via analytics, ads, other embedded contents are termed as non-necessary cookies. Not very well known in Europe and therefore hardly available. I have two subs connected to my rig. Many subwoofer crossovers have a fixed high pass for the main speakers at 80 Hz, effectively taking them out of the bass equation. No, I didn’t. and if so, that would be really handy (and inexpensive). When I asked the electrician about this after the fact, he said that the neutral wire also serves as the ground, and that it is ok to do this in a subpanel. Both is not really good unfortunately. When Paul wrote on this subject a year or more ago, I went back and re-wired my subs to use the speaker level inputs as he describes here. Wiring (a process of connecting various accessories for distribution of electrical energy from supplier’s meter board to home appliances such as lamps, fans and other domestic appliances is known as Electrical Wiring) can be done using two methods which are I currently run a Peachtree, but it is an older model without the TT ground. The earthing arrangment for the instalation is TT. It seems to me that because of the room resonance phenomenon that affects all but auditorium-sized rooms, optimum full-range sound would be achieved by either a full-range speaker with a powered woofer that can be parametrically equalized, or a small speaker-sub combination with the sub’s low pass designed to be under the typical room resonance range, allowing the room gain to extend the small speaker’s normal bass response. Mine has the outboard power supply. Anyone of them will assist you in completing the wiring process for the subwoofer system. Since I also upgraded my primary speakers at the same time as the renovation, it’s hard to now say what effect the signal source has on the overall sound, but I remain pleased with the way it all sounds. There are two main ways to add a subwoofer to your PA: via a crossover network or via a special submix. This works, but would not be my first choice. The DSP on the ver 2 fathoms is Amazing. I will attest to the fact that I heard a difference in my system and wrote at the time that “I was never going back”. A reliable and dependable electrician must carry this out. When I moved to kits that had subwoofer pre-outs, I started using them (which was 20+ years ago). Free shipping. A distribution switchboard is the point that the incoming power supply divides into separate circuits. But people solved this and it seems to sound good as probably many of you really compared. It is also worthwhile to note the distance you are taking the power outside, the earthing system and the usage. Integrates beautifully. Paul. I use one for a mono subwoofer, the other is programmed as my DVD digital input. There might be preamps which are too weak for the job and therefore worse from start than a high level connection. Wire the mains out of phase and adjust the subs phase knob until you hear a big null. Figure 3.6 Underground network and underground consumers mains Figure 3.7 Typical underground service to multi-lot built strata In addition, network operators should be consulted regarding their connection requirements. The Crossover Method The more popular method (and the one used by virtually every house PA system) is to run the output of the mixing console through a crossover network, which splits the signal into multiple frequency bands and sends each band to a different … allowing for seamless integration. Some subwoofers have a high-level input that can accept the main power amp’s speaker outputs. As I haven’t tried it, I can’t tell about it. Skip to main content. From the sub high-level ouput to the speakers I used my Tellerium Q Black II cables. There might be preamps which are too weak for the job and therefore worse from start than a high level connection”. As for your remark/question I can only tell you what REL (being on of the best sub manufacturers in the world) has to say about this : 2 hot and 1 neutral, no separate ground. This necessarily requires that the main speakers not be rolled off by a high-pass filter. This is not necessarily optimal but has the greatest chance of exciting the fewest room resonances. The sub will suck nearly no current from the signal (so your mains will still get almost all the juice), expensive subs have nice crossovers you can use in this configuration. Put your sub where your head normally is and craw around the room while playing deep bass loaded music and listen for the cleanest sound. The wrinkle with regards to the high level input on a class D amp is the introduction of humming from the sub. I agree subs should be sealed. I’d forgotten about the duplicate outs. I didn’t read a clear recommendation in any other manual of a sub manufacturer, but I remember at the time when I cared about it, might it be Revel or another manufacturer, it was more a support recommendation to use low level inputs. $13.99. I traced that down to having the rca input cables hooked up wrong. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. So, digital parametric equalizers/RTAs are a godsend in being able to juggle all of this successfully and without operator interaction (although some care is needed in choosing a position for the calibration microphone). The sub main I plan to take off from a henly block. Each of them are protected and controlled by fuses of the switchboard. Exception: This requirement need not apply to wiring systems that can move freely to a point not less than 50 … 40 AMP Shower Wire (10mm) 32 AMP cooker wire (6mm) 20 AMP running a SWA for one socket and light to a shed where a sewing machine is used. It enters the house via the live wire, which carries the incoming electricity. This identifies the flattest position for a single sub in x and y coordinates. Ask an electrician to provide sub mains power installation. The difference between high and low level inputs isn’t subtle. And want to add a sub is not a sub unless it can reproduce 20hz or below without large amounts of distortion. Dealing with that is the key to a decent sounding subwoofer setup. The current powered REL subs, like my 15-year old Storm III, connects the amp output terminals through a 3-wire cable and Neutrik connector [unbalanced] to the high-level input of the sub. In the case of an electrical switchboard, used for particular things, they may be located to the main low voltage switchboard or near where the application is. We touched briefly on subwoofers and speaker setup in yesterday’s post. If you’d like to learn more on this subject, WATCH THIS VIDEO I prepared for you. Now since I plan to stick with this configuration, I presume that I need to buy another pair if Tellerium Q (from amp to sub) as I need to keep the cable quality consistent, isn’t it? Do i need to install an RCD at my 60 amp main switch from the board to protect my armoured cable? While looking around for the problem I noticed that moving the m700 input cables around changed the level of hum and buzz. Secondly an external crossover I think usually is the best solution…” He says you need 4. This is the only way to get it “right” You can adjust everything in real time and watch the results. I was very interested that you recommended taking the feed for a sub from the power amplifier in order to preserve a consistent sonic character. It works for *my* room. The advantage of using the second method is maintaining the sound quality of the power amplifier. The pattern of power usage you expect to make in the building outside your business. Regards. RCA/Coax connections are better than nothing, but speaker cable is just better for stereo. Security & Assistance System Installation, Small Commercial Electrical Installations, Tendering & Procurement of Building Contracts. TT system. If a preamp has enough gain to drive an amplifier it will have enough gain to drive another output to say a sub. Using a switchboard, the electricity is directed out of your home into another place, through wires. https://www.crutchfield.com › ... › subwoofers_wiring.html There is a ground bar installed in the panel, but no wires connect to it. That said, it does exist and you can choose to either ignore it or swing with it. Make sure you DO NOT ground the negative output of a class D amp because that side is actually floating above ground and if you short it to ground you might let the magic smoke out. Moving the electricity outside, you need to consult with someone informed about what you are doing to gain the appropriate advice. Is there any advantage when using a pair of subwoofers to setting them up in a stereo configuration (one for the left channel and the other for the right channel)? But REL refers to the sonic signature of the whole entire electronic chain as advantage when using high input (as Paul stated), “Secondly an external crossover I think usually is the best solution…”. It is not perfect – nothing below 100 hz in a multi-purpose listening room like mine, can take account of all the reflections and refractions which double and suck out frequency responses. The newer method of dealing with this, introduced by Velodyne I believe, is to put a parametric equalizer/real time analyzer in front of the sub to trim the sub’s response to the particular room that it’s in. A plan is crucial! Through the high level input, the sub disappears into the mains. We use cookies to ensure that we give you the best experience on our website. Buying an amp wiring kit isn’t like buying a USB cable or adapter plug. If you have the cash and are not concerned about everyone having good bass, get a JL audio V2 and put it most anywhere. Thanks! Change the phase on the left sub and then you need to change the right sub which means the left needs to be fixed which means the right needs to be fixed, and so on. quote : I am just making sure am I doing the … The Persona 9F is, for my money, one of the most transparent and dynamic speakers I’ve ever auditioned, and it’s largely due to their philosophy and execution on bass. October 12, 2017 by Paul McGowan. If I remove the metal jumpers and make the connection of the Sub to the pre-amp, do I restore the connection between the pre and main amps by using a splitter cable from each channel, ie one side of the splitter to the amp and one to the Sub for each channel? Remove the lowest amp rated circuit breaker from the main panel to make space for the new sub panel, then route or extend the wires to the new panel. No complicated measurements. Also, my system sounds much better to me using the speaker level inputs on the subwoofers. These can take an analogue signal, do A/D, then do the DSP and then D/A to the main speakers and subwoofers. But I sure hope REL knows what they are talking about. or Best Offer. cheers. First of all, connect the single-phase energy meter to the mains supply i.e. Would be great if power amp manufacturers would supply this by factory. Now I will have to start thinking about upgrades. Figure out where you're going to place the amp, put the … Run your amp wires (battery, ground). According to Dr. Floyd Toole the best locations for sub woofers are in the four corners of a room. Here at Atom Electrical Solutions Ltd, we will provide an excellent service of mains and sub mains power installation! In fact, the sub was on all night and seems to have knocked out my internet. Sub-Main Distribution Boards The MDB then feeds SMDBs, which is installed generally at the point where a large distribution cable terminates and several smaller sub-circuits start. My favorite method is to tap the output of the loudspeaker power amplifier instead. Solar panel wiring (aka stringing), and how to string solar panels together, is a fundamental topic for any solar installer. Paul, A good preamp can sound better than no preamp at all. Interestingly, with my BHK signature preamp, I’m using the balanced outputs to my power amp and the single-ended outputs to my subwoofer – nice feature of the preamp to be able to use both outputs concurrently. Audiophiles may prefer the much more expensive and very clever Illusonic devices. Likewise, an active crossover can achieve a much better integration of the subwoofer with the main speakers without doing any sonic harm. But the fact that the timbre of the power amp is carried through to the sub makes a huge difference in integrating the sub sound into the main speakers. My dealer has been a REL main dealer since they started and advised no filters at all and set the volume, crossover and slope on the back of the REL. I have to say though that I don’t know what it’s like when you have a (pre-) amp with a sub output. We all have our preferences there. That’s what I was wondering. But it’s one step back and four steps forward. The main subwoofer is not too complex, and before connecting the subwoofer to the main speakers or the sound systems, you will have to find out whether you will have to connect additional wires at the rear of the subwoofer. Now for details of placing of sub woofers this would be very helpful. Now put the sub there. If you buy the wrong amplifier kit then you're going to get terrible sound in your car or no sound at all. These are the switchboards that although similar construction, are larger than a … http://www.dspeaker.com/en/products/anti-mode-8033.shtml, https://www.stereophile.com/content/music-round-34-page-2, http://www.acousticfrontiers.com/devialet-subwoofer-crossover/, https://rel.net/connect-rel-class-d-gear/. While this allows the sub’s response to be adjusted to blend with the main speaker’s, it leaves it delivering full output at the room’s resonant frequency, which typically adds a 6 dB gain—hence “room boom” and all sorts of sonically bad stuff. Another (unnecessary) element in the chain. I prefer to swing with it and take advantage of the synergy. On the contrary, they recommend it. Yes, I had a PCA 2 quite a few years ago, nice pre. There are only 3 conductors between the main and sub. We also use third-party cookies that help us analyze and understand how you use this website. You do NOT want to ever hear the sub. The amp doesn’t even know the sub is there. cheers. Why choose ATOM as your Commercial Electrician? I have a Focal Sub 300 P with high level inputs (via the speaker cables) and low level via RCA from the pre-amp. The internet promptly came back when I turned the sub off manually. We do not believe in running your speakers “full range”, bringing the sub in where the speakers roll off, though if you really want to do that then see our article on how to do it.. We’re advocates of actively rolling off the bass to your speakers, combining the left and right signals to mono, and … My sub is not a REL, but I can see that REL has instructions on how to use high level connections with class D amps for their subs (https://rel.net/connect-rel-class-d-gear/).
