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. No matter how good an electronic crossover is it will still have a sonic signature. If you buy the wrong amplifier kit then you're going to get terrible sound in your car or no sound at all. A much cleaner, better sounding way of doing this is with the use of a Y connector at the amp. 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. A good preamp can sound better than no preamp at all. d) The method of earthing a distribution board in an outbuilding, must comply with either the system described in b or in c, as above. For me sonic character is another term for distortion, although not all forms of distortion are unwelcome. Solar panel wiring (aka stringing), and how to string solar panels together, is a fundamental topic for any solar installer. The two refers to the main pair of stereo (left and right) speakers, while the '.1' refers to the limited-bandwidth subwoofer. 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? My favorite method is to tap the output of the loudspeaker power amplifier instead. Ignore the high level input method unless you have a system where it’s the only way. Isn’t it that a second pair (or single) speaker at the amps terminals vary the load for the amp? It is not recommended that you carry out this yourself. Sorry, this is tough. Yes, two (easy) ways to hookup a powered sub in a 2-channel setup. We only want to make believe our main speakers have low-frequency extension (which most do not). There are two main ways to add a subwoofer to your PA: via a crossover network or via a special submix. When I moved to kits that had subwoofer pre-outs, I started using them (which was 20+ years ago). I traced that down to having the rca input cables hooked up wrong. You are allowed to retrofit a separate equipment ground wire. These cookies do not store any personal information. and if so, that would be really handy (and inexpensive). I agree subs should be sealed. $13.39. High level input on a class D amp introduces ground loop. But people solved this and it seems to sound good as probably many of you really compared. It should be noted that frequencies in the sub-bass range of a delay system do not require distribution. Integrates beautifully. Another (unnecessary) element in the chain. Preamplifiers aren’t especially appreciative of the cables that connect them to amplifiers. DSP devices. 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. On the contrary, they recommend it. Sigh. If you continue to use this site we will assume that you are happy with it. By the way, regarding so called “subwoofer cables” how many of you use a specific cable labeled “subwoofer” as opposed to just a standard RCA ended cable for coax, or otherwise? another option i read is to jumper from the towers to the subs; is that wise? 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. 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. With some web search one finds many references to high level connections, but all referring to the REL article with mostly the same words from their manual which also Paul used, not one hint from another manufacturer, just one saying JM audio recommends the opposite and another one claiming he was REL dealer and the high level theory was their story and BS. Adding two more subs helps also. i recently decided this is sort of dumb, and am now running separate sets of speaker cables to the subs and the towers, from the same amp (carver m500t). Always busy with the hobby. There are a range of distribution boards, which differ depending on the type of application and the design code. This is probably the biggest issue facing home audio enthusiasts. Methods of Electrical Wiring Systems w.r.t Taking Connection. I have a Focal Sub 300 P with high level inputs (via the speaker cables) and low level via RCA from the pre-amp. I initially had a hum/ buzz when I used the +output of the mu00 amp and the amps chassis (as – connection). The problem with cables and subwoofers is two-fold: double-long interconnects and a missed opportunity and synergy. At 50′ of run between the receiver and the subs, I am back to the receiver’s LFE out/in to the subs instead. Reverse the phase. allowing for seamless integration. Did he read his own department’s research papers? Dropping all that energy out of the main amps and main speakers is a real boon. 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. I was at the AES seminar when Sean Olive and Todd Welty presented the Harman paper on multiple subwoofers. However, a sub-mains circuit is defined as a circuit that is directly from the main low voltage switchboard, to the sub-main distribution panel. 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. Was: $14.73. I agree to Atom Electrical Solutions privacy policy. 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? Secondly, any decently-designed pair of small speakers simply does not produce output when driven below its bass capabilities; it does not produce distortion. Through the high level input, the sub disappears into the mains. If in doubt call the maker of the sub (and the amplifier your using) and ask them how to proceed. They took the cheapest speaker in a line, added an active crossover and a sub or two and claimed, let’s say 90% of the performance of the largest speaker in the line. And we all know our hobby is the most subjective hobby in the world, as far as soundquality is concerned. If you have a pair of pizza boxes, as plenty of people do, you then have four programmable pre-amp subwoofer outputs. If your subwoofers support high level inputs from the power amplifier outputs, I would use that method. 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. That’s also my experience. on either or both the main and sub speakers. The current flows in one direction, then the opposite, continuously. Does the active add a layer of electronic signature. An electrician from Atom Electrical Solutions Ltd can make sure that your sub mains power installation is carried out to the best standard possible. Both is not really good unfortunately. No, I didn’t. Separate crossovers are far superior sounding than their addition to the circuit might theoretically imply. A short interconnect from the Y connector to the subwoofer completes the circuit. I think I hear quite a bit, but I doubt, I would hear synergy aspects below 30Hz except phase issues. I did the above when I hooked up my Sumiko S9 subs high level (speakon) to my m700 amps and it worked great. Although much of the electrician's field terminology matches that of the electrical codes, usages can vary: . I never heard JL Audio, alas. Not very well known in Europe and therefore hardly available. 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. Replies to my comments An electric switchboard is an appliance which directs the electricity from one large source of supply to multiple smaller usage regions. So I’m curious to hear which manufacturers consider this as worse. His hobbies include hiking, skiing, cooking, artisan bread baking. IMO the best subwoofers will be acoustic suspension models and Newton’s second law of motion explains the major reason why. https://www.crutchfield.com › ... › subwoofers_wiring.html 6. Any comments on how best to make the connection: Hi level with the speaker cables for either of the Low level? The problems dealing with all of this successfully are far greater than any sonic degradation caused by introducing an equalizer into the signal chain. These are the switchboards that although similar construction, are larger than a … If I had a component system and lots of money, I’d have one of those. This is the only way to get it “right” You can adjust everything in real time and watch the results. i have read the whole thread and read/watched (possibly) everything what mr. mcgowan has to say about subwoofers. A topic for another day. Thank you, Yes, I had a PCA 2 quite a few years ago, nice pre. He will probably be Swiss, so no jokes allowed. I’d be curious to learn Paul’s experience with external crossovers, as they seem (to me) to be the way to “go the extra mile and complete your system” (as in the original post). 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 … We'll assume you're ok with this, but you can opt-out if you wish. In this scenario, you have one cable between the preamp and amplifier (with a Y connector at the amp’s input). Moving the electricity outside, you need to consult with someone informed about what you are doing to gain the appropriate advice. I have two subs connected to my rig. 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. Using the (sub) high level input gives a far better synergy. What? How much power do you need? I guess it would be a pretty bad signal, but under 30Hz, maybe this doesn’t matter that much. Security & Assistance System Installation, Small Commercial Electrical Installations, Tendering & Procurement of Building Contracts. I think there are various far more relevant aspects to integration of a sub than to use low or high level inputs. HIGH PERFORMANCE HOME AUDIO PRODUCTS The difference between high and low level inputs isn’t subtle. That's a very significant advantage, but in a 5.1-channel wireless subwoofer-speaker system, you'll have to deal with six AC power … Use any practical route you please, there's no requirement that it run with the power cable. In the design process you need to work out how you are going to achieve each part of the installation. Likewise, an active crossover can achieve a much better integration of the subwoofer with the main speakers without doing any sonic harm. There are other very effective methods. 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. Mains electricity is the term used to refer to the electrical supply coming from a power station to the household you live in. The current flows in one direction, then the opposite, continuously. Especially when I read that we basically only need our ears. I may even try it myself someday. 3.2 Earthing System Earthing systems shall comply with the relevant technical standards, including: • the Wiring Rules; Since each of the setups has different speakers, different amps/preamps and different brand subs it’s hard to know what effect this has on the overall sound of eachbut for now I certainly am enjoying the sound coming from all of the various locations, which to me is probably the thing that counts most! This scheme also avoids adding any detrimental effects by not also, that many rca cable runs would most likely catch interference. Mains power installation can be difficult to understand. 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. It works for *my* room. You can view his efforts at http://www.paulmcgowan.com. You could be correct about this jb4, I just like to start arguments sometimes. Alternatively, it has been suggested I connect the Sub by RCA to the Tape-rec out channels of the amp. You need to understand how different stringing configurations impact the voltage, current, and power of a solar array. This category only includes cookies that ensures basic functionalities and security features of the website. https://www.stereophile.com/content/music-round-34-page-2 I uses a PASS XVR-1 with my two way Harbeths and a couple of JL subs and effortlessly fill a 5500 cubic foot listening room. 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.
