christ1 Posted October 9, 2012 Share Posted October 9, 2012 I am thinking about getting a seperate amplifier for my three front speakers with the surround speakers connected to the receiver. I am confused how the volume is controlled because some sellers talk about remotes with the amp, but they never seem to have them. Does it basically work the same way as a powered sub connected to the preout on the receiver? Using the receiver volume control changes the volume of all speakers including the sub in unison, so if the front three speakers are sent via the preouts to a separate amplifier then the volume would change in unison the same way, right? Thanks. Quote Link to comment Share on other sites More sharing options...
Moderators Youthman Posted October 9, 2012 Moderators Share Posted October 9, 2012 My Parasound amp has Level Controls for each channel. Below is from the manual. Level ControlsEach channel has its own rear mounted "set and forget" input level control. Your amplifier willsound best with these level controls set to maximum, where they are effectively out of the audiosignal path. However, if your preamplifier has very high gain, and its volume control cannot trackproperly for left-right channel balance near its minimum position, it may be necessary to reduce theinput level control settings on the amplifier. When using the HCA-2205A in a THX installation, eachlevel control must be set at maximum to correspond to 0 dB THX reference level. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted October 9, 2012 Share Posted October 9, 2012 It all depends on which amps you are going to get I have some vitage amps and I turn the gain to the max and let the avr's pre-amp set the correct signal for all the speakers Some vintage amps don't have gain control, so the pre-amp with determine the signal to be sent to the speaker. All speaker volume are controled via the avr. I hope that helps. Either way you should not need separate remotes for everything Quote Link to comment Share on other sites More sharing options...
christ1 Posted October 10, 2012 Author Share Posted October 10, 2012 Yes that answers my question. I was confused on how does the amp "know" how much amplying to do. I guess what I was missing is that the preamp part of the receiver modulates the signal to the amplifier, which does not matter whether it is an internal amplifier (receiver) or a separate amplifer. Each channel is modulated in the same way so that the speakers stay in balance (assuming they were calibrated when first set up). If the amp has a gain control then that is a way to change the amplification manually but is meant to be used only when calibrating. Thanks.

Scrappydue Posted October 11, 2012 Share Posted October 11, 2012 Buy an emotiva xpa-3. No volume. Just run rca's to it and enjoy! Quote Link to comment Share on other sites More sharing options...
christ1 Posted October 11, 2012 Author Share Posted October 11, 2012 That is probably what i would get. It seems that it cannot be beat with its price/performance ratio, especially for a used one. Quote Link to comment Share on other sites More sharing options...

I found one local after talking with Williand and am solo thankful I did take his advice. It's a beast and the soundstage is great on it with more then plenty of headroom Quote Link to comment Share on other sites More sharing options...
christ1 Posted October 13, 2012 Author Share Posted October 13, 2012 Thanks for the info. I am not in a position to buy anything yet, but I will certainly keep my eye out for Acurus when I do. Quote Link to comment Share on other sites More sharing options...
