Geoff, if I understand you correctly:

In the "infrared hand-held learning-phase" you are asked to assign keys of your hand-held to invoke: "Volume Up, Volume Down, Mute, ...".
I can easily add a new function (option) called "Tape", and you will be asked to assign a key on your hand-held to this function.

When you press this key, the HomeTheatre relay will be closed and the string "Tape" will be displayed on the LCD.
The output of the relay will then show the unattenuated signal.
Pressing this key once more, will open the relay, showing the attenuated signal.

Best regards - Rudi_Ratlos

That's correct but note that the unattenuated signal from the output of that relay will be routed back into the mute/attenuation circuits of the VCPre.

In 'normal' mode the Tape Out RCA gets the unattenuated signal from the selected source and the amplifier gets the attenuated signal. In 'Tape' mode the amplifier gets the attenuated signal from the Tape In RCA whilst the Tape Out RCA continues to get the unattenuated signal from the selected source. I believe this is a common way that integrated amplifiers implement their Tape In/Out.

Regards
Geoff

It would be nice to use it like a tape loop if you wanted to use a outboard processor like mini DSP.

Yep. It allows you to put something in-line after the source-select and before the mute/attenuation. It doesn't have to be a tape unit (despite the name I used).

Geoff, Bill, I would do it this way (see image attached).

rudi once again thanks for all your great work on this! is there any way firmware support could be added for manual source selection via momentary push buttons? there was a silicon chip preamp published in 2005 based on similar hardware where the firmware would poll the pic io lines that drive the relays so see if they had been pulled low by a pb switch.

Hi Rudi_Ratlos,

I've just been re-reading the thread, and I was wondering how you wire up your VCPre to get the manual source selction, as indicated in the picture in post #209?
Is the manual selection additionaly to the remote selection, or do you plan to just have the switch on the amplifier?

Thanks for enlightening me!
