Pre-Amp Pass Through Loop

Have a Classe CP-60 pre amp with a surround sound processor pass through. My question is exactly what does the pass thru do? Are the signals going to all 5 speakers being impacted at all from the pre-amp? If not is the surround sound processors sound enhanced when it routes through the pre-amp? Any clarification provided will be much appreciated. Thanks

It allows for an external pro to be used and the ht pass through routes the signals to the amp it is connected to yet volume is controled by the pro. Your preamp should then be in a pass through mode and not touch the signal.

Mdomnick is correct. I also have the Classe CP-60. I have the preamp output from my Denon AVR receiver input into the CP-60 SSP loop. This allows me to use my mains in HT without detracting performance from my two channel system. When the SSP is engaged, no functions on the CP-60 operate, not even volume, since it is unity gain. The Denon controls ALL the speakers volumes.

John

Appreciate both of the responses. John, how big a detraction would the Classe SSP 75 be versus the CP 60. Thinking about upgrading HT, but don't want to give up a lot of two channel.

Thanks,
Ken
