Hi all! I am needing a little help connecting a subwoofer to my receiver. I have a powered Yamaha subwoofer that only has one singular Subwoofer Out port (LFE). However, my receiver does not have a Sub In connection, only Speaker B connections (speaker wire/banana cable) that have nothing plugged into them. My thought is that I can connect the sub to the receiver and turn on both A+B speakers. Is it possible to go from my sub to the receiver? If so, what is the best method and what sort of cables would I need? Thanks in advance!
Without knowing what equipment can't help. It sounds like the sun is a HT model with only a LFE line input. You can't use speaker outputs to drive it. What model is the receiver? you may need something like this Russound ADP-1.2 Speaker-level to Line-level Adapter
Your receiver has line outs but they won't work. No volume control. You need a speaker level to line level adapter, one that combines to mono if you can find one.
A while ago I was using an integrated amp with only speaker outs. I used one of these with my sub. The only issue is it doesn't offer a mono out. https://www.amazon.com/Converter-BO...lkZ2V0TmFtZT1zcF9tdGY&smid=ABO907060G8YG&th=1
I've looked through the owner's manuals for both the sub and receiver and... I think the best option is to sell the sub and get something that will work with that receiver. Trying to make it work is a kluge at best. It's part of a full surround sound speaker package designed to work with an AVR that has a line level subwoofer output (and bass management). Look for a sub that has speaker-level inputs, and better yet, speaker level-inputs AND outputs, with a high pass filter, since your receiver is not capable of doing bass management. THAT will sound way way better than the kluge approach. Jeff
Not to leave the OP hanging, here's a very specific suggestion for a sub that would work great with his receiver: the Definitive Technology ProSub 800. A quick search finds one for sale here. To add a little cred to my suggestion... First off, I'm a big fan of low-priced Yamaha "YST" subs. I use a few of them in a variety of "budget" systems around my home. But as I mentioned in my previous post, the OP's sub is a very bare-bones (functionality-wise) Yamaha sub - albeit "YST." In addition, I happen to own and use a Def Tech ProSub 800 - which I bought a few years ago at a thrift store for next to nothing. I've used it as part of an outdoor "driveway" theatre where I showed a variety of open-air movies for my neighbours during Covid's darkest hours. (No problem with Rocky Horror at very high volume levels during my Halloween offering last year!) I'm currently using it in my just-built basement library, in support of a pair of Minimus-7 speakers. It does not get more budget than that. With its fixed 80 Hz HPF, the Def Tech sub provides solid bass support well down into the '30s, while taking the load off the Minimus-7s. Jeff
You could try this for under $20: 1. Connect speaker leads of this adapter to the "B" terminals on the rear of your receiver 2. Connect this "stereo-to-mono" adapter to the outputs of adapter above 3. Connect mono adapter to the input on your sub using this cable. Set speaker selector on receiver to "A+B". Receiver volume knob will control volume to your main speakers and also the sub. Use the level control on rear of sub to set volume relative to the mains. Hopefully, it will maintain that balance as you change volume on the receiver. As said above, it's a "kludge" but should work reasonably well if you don't want to spend much.
Do you have the owners manual for the sub? If not look online for a pdf of same. I bet Yamaha will suggest possible or likely connection schemes. Also, https://www.dspeaker.com/ would work, though not free/cheap. Foster
Manual As I said in my first post, the sub is part of a 5.1 surround speaker package. And as such it has but an ON/OFF button, line-level RCA input, and volume control. It is intended to be used with an AVR that will handle the bass management duties. The manual gives but one connection scheme: connect RCA cable from AVR to sub input. Jeff
Jeff -- thank you so much, this is actually really helpful. My gut is telling me to just get a different sub with speaker-level inputs... but I also kind of want to try and make this work. Thanks very much for your knowledge!
This is true. I got the sub as a freebie with something else I bought so just trying to see what I can do with it.
