Use Stereo Integrated AMP as a Mono Block

Mono blocks benefit from physical separation and separate power supplies, which you won't have with this arrangement.

That’ll work, but you might need to set a “reference” volume level on the Exposure (I used to use 12:00 as it’s consistent and easily repeatable) when you set the individual speaker volume levels with the Denon unless the Exposure’s A/V input acts like an HT bypass and puts it into unity gain, then you don’t have to worry about the volume control because it’s out of the picture.

As a follow-up question, is this strictly a HT system or is it also for 2-channel listening? Just asking because there may be another more preferable hookup option here.

Thank you for the inputs, yes its only for HT setup. And I dont have the control on the volume on my exposure when I connect as AV. But I do have the Denon volume level to setup individually for the center.

I have Exposure 3510 Integrated amp.

It has the HT ByPASS as you said. Thank you soix.
