Would this be suitable for increasing the gain on a Yamaha RX-V375 AV Receiver's preamp output for a powered sub? I'm going into an unusual sub: directly into the amp of a modified Logitech Z680.

yes it will, but you may end up with hum, it is a tube preamp, it does have a bass guitar setting. you can return it, so hell try it.

Throw it directly into the input. It works great as a booster where you crank the level and cut back on the gain. I use mine to fill out the tone of the lead channels on my 6505 and DSL50. Also dump the cheap Chinese tube and opt for a JJ or Tungsol. I applied the Bitmo Monstrosity mod to mine and it is a must in my opinion.

The quick answer is "yes". How ever, I purchased this amp to allow me to "bi-amp" a set of Polk tower speakers (add some "punch" to my system). Connecting the amp to my Yamaha RX-A3020 and to the Polk towers, produced a low frequency hum. Assuming your sub would also be subject to this. I found out, this amp is made for commercial loudspeaker (clubs/disc jocks) where a low level hum is completely unnoticed. In a home theater/livingroom application, I don't think this is tolerable. It will work, if you don't mind the humm. I will sell you mine, cheap :-) ...used all of a couple of hours.

It won't matter. If there are two (left and right) lines into the sub's built in amp, they are wired in parallel.But, if you have two subwoofer/l.f.e. outputs from your receiver, you might want to use both of them to give you the strongest input voltage to the sub. I don't see how using a "y" adapter to go into both inputs could possibly hurt though. It just wouldn't accomplish anything.

This is over kill for a home theater system, we use it on stage PA. You would be better off getting a surround sound amplifier that has subwoofer connections already built in.

this amp will provide more power than needed for the rms setup you have. which you can adjust the gains accordingly

you will have to run the preamp into to an aux. input for it to work. The preamp boosts the signal to a level that the receiver can handle.

Hi, I have my Emotiva UPA-700 connected to a Marantz SR6007 Home Theater AV Receiver. I felt that the sound is not louder, but it is clearer. I tested it to see if it was worth keeping the Emotiva. I felt it was worth it. Also, as an FYI - Since I have 4 ohm impedance Dynaudio speakers I decided to go with a separate amp to protect my receiver. The thing that surprised me the most was my volume level is at about the 2/3rd level. (With my earlier Yamaha receiver without any amp, it was usually at the 1/4th level).

If your receiver is pushing more watts per channel then this amp will not be louder. But the quality of sound produced by the Emotiva will more than likely be a large improvement, unless you own a high-end receiver (normally costing thousands of dollars).

I am not sure what you are trying to accomplish. The UMC-200 is a pre-amp and you still would need an amplifier. I don't think the Yamaha 775 has pre amp inputs so you cannot use it as an amp. Don't get me wrong the UMC-200 is a good piece, but I am not sure what you are trying to gain or how you are planning on hooking it up.

No the ohms won't matter. If your receiver has the subwoofer RCA port you can run that to the subwoofer. If not you can wire it through the speakers. I would try both and see if you notice any difference and choose the one that gives you the best performance. I've had the best luck, performance and reliability with Yamaha receivers. I have one thats 15 years old and is great. It has the digital optical port for the Dolby Digital surround sound so I haven't bothered getting a newer one. I referred my friend to the Yamaha RXV 377 and she loves it.

Bill, I doubt anything "went wrong", but the Yamaha may not deal with potential impedance differences between your main speakers and your sub. Luckily, Yamaha allows you to set up levels for each set of speakers (front, center, back, sub) from within the setup menus. Using the remote, do the following:setup -> speaker -> level -> scroll down to "sub" and raise the level (default is flat (0db)) until you like how it sounds. hope this helps,gfd

My comment is that I agree that underpowered receivers or amps will easily damage your speakers. I learned the hard way when I was a teenager 25 years ago and the receivers I used then blew tweeters. Then I bought a Carver amp and felt the difference. At this time, I have Carver amps driving L/R/C/Sub Channels on my system. It is safer to have a 250RMS Watts per channel amp than a 40watt receiver.

Yes. As long as you have a receiver that does at least 5.1. Plus you need to make sure the inputs for the sub match the inputs for the receiver. Otherwise you may need some adapters to get it to work.I use 4 of these with one center channel being a different Yamaha and it sounds great. My family just visited this weekend and commented about how awesome it was.

Thank you for asking. This sub is designed to take a line level signal. Without a preamp of some sort like a small mixer an iPod will not reach the potential of this amp and speaker, however you make get something from it if you had a cable that is 1/8" (3.5mm) stereo on one side and dual XLR on the other. You would need some mains for it to sound right as this is only a subwoofer so it does not provide full range audio.

run it clean,no gain it will sound great.if you use the gain ,its all you will need..it has plenty of gain

Yes, certainly. I'm personally using a Boston Acoustics brand sub. You may be interested to know I have the speakers and sub controlled through a very inexpensive but wonderful preamp, (Gemini PA-7000). To achieve good balance you may be surprised to learn I have the sub itself turned as low as possible. In other words, the A+ speakers themselves are themselves quite bassy - also, found I needed to lower the subs crossover all the way to 75 or 80 cycles. Quite amazing. The biggest advantage of the preamp is to be able to adjust to various source signals. So, I guess the short answer is -- Yes
