Well, another pre-amp & HT integration question...

Hi Thomas

I will try to list the hook up.

DVD player--->HT Processor----> HT Processor left and right line level outputs---> Pre-Amp Processor loop input----> Pre-Amp main left and right output to amp/amps for front left and right speaker.

HT Processor Center, REAR left and right line level outputs to Center, REAR left and right amps and so on if 7.1 exc.

Select Processor loop on Pre-Amp use remote/HT volume control to contol volume.

When you select Processor loop setting on the Pre-Amp it will automaticly place itself in passive mode and have no effect on volume control. No setting or volume matching require. The only volume concerns is controlled by the HT processor.

NEXT

Transport--->DAC---> CD input to Pre-Amp---> Pre-Amp Main left and right already to ftont left and right Amp. Exit Processor Loop, Select CD and now use Pre-amp remote/Volume to control volume as Processor is no longer in loop.

Works the same for a source equipment. To listen to what is hooked to the HT Processor select the input on the HT Processor for the unit. Select Processor Loop on Pre-Amp and use HT processor to control volume.

To listen to any source hooked to the Pre-Amp make sure the Processor Loop is not selected, then select the Pre-Amp input that the unit is hooked to and listen useing the Pre-Amp to control Volume.

You will most likely want to have 2 channel transport and such go straight to the Pre-Amp not the HT Processor. If the source player/transport is the same unit then the Digital signal goes to the HT Processor nd the analog outputs from player/Dac will go to the Pre-Amp direct.

Hope this with previous post helps clear things up

Hi Thomas
In your last message you state that you would be using the analog output from the AVP to the Pre-Amp.

Is the analog outputs fixed level outputs. By this I mean there may be outputs for the DAC'S that may not have volume control. If it does then you wound take that to say the AUX,orCD input on the Tube Pre-Amp. BE SURE THOUGH THAT IT IS A FIXED LEVEL OUTPUT. You woud be useing it like any other input and then the Pre-Amp controls the volume

If you are talking about you main speaker outputs then they would have to go to the processor loop in. Then the Process will control volume.

If you want to get a gain from a Tube Pre-Amp you need to be able to get an analog fixed level signal from the DAC (may be by way of fixed level analog output from the AVP) to a Pre-Amp input, for it to use as an incoming signal.

I would check the owner manuals to see what you have.

Hi Thomas
Just seen you new Post and I am not up on what the Proceed AVP will do, so can not help much there. But the last post connection should work on most systems.

Hope my last post will help. But not sure why you would run the 2 channel source to the AVP at all. Go straight to the Pre-Amp inputs with your analog outputs from the player or the DAC which ever you use.

For me I wanted the Tube Pre-Amp sound for 2 Channel. Again to me both the Audio Research and the Conrad Johnson is so much more musical than my Lexicon MC-1 that I want to remove the Lexicon out of the 2 channel mode. I also did not want to have to switch the interconnects each time. With the above the surround processor is removed from the system allowing total control of the 2 channel from start to end with only the 2 channel system in line.

Thanks for all your input. It's much appreciated. Here's the way my system works and why I'm having the questions:

Source - Proceed PMDT, this is a DVD/CD transport, digital output only with cards for progressive scan video output. It also acts as a video switcher to take in output from other video devices and translate them also to 480p output. Sounds great with redbook CD. So all source material goes through this unit.

DAC/HT Processor/Pre-amp - Proceed AVP, this does everything, D/A conversion, surround sound, normal pre-amp functions.

So to add a regular two channel pre-amp, it has to come into the path after the AVP in order to receive an analog signal. The source for DVD home theater and 2-channel CD is the _same_. Thus, the conundrum with how to isolate the control functions of the AVP while still using it as a DAC to send analog output to the proposed tube pre-amp.

It can be done, it's just how tedious and how much signal degradation will be involved. If only I has the space and $$ for two complete systems...

Best,

Thomas

I can't fathom the benefit of running out of the AVP to yet another preamp. You don't need any more gain, nor input switching. I'd think you'd either do something in lieu of the AVP or call it a day.
