Adding Center Channel

I currently have my 2 channel providing the Audio for my projector. Unless I turn the volume up significantly the dialog is too low. I was told adding a inexpensive AV Receiver and center channel would help, so I did. I purchased a Marantz NR1607 and Monitor Audio Gold center channel. The NR1607 is used to drive the center channel only. The problem is I hear dialog through my main speakers before I hear it through the center channel. It almost sounds like an echo. I've tried everything and I can't solve the problem. Is it because I have two different amps(1 driving the main speakers and the AV receiver for the center channel)? I've contacted Marantz and Oppo via the phone and they couldn't resolve the issue. Any suggestions?

Hi Ric,

On many HT receivers, there is in the setup menu a method to sync the audio via delay settings. Have you exhausted all means in the settings?

This should be an easy fix, although some menu setups can be quite confusing, even for techs.

Good luck,Dan

Adjusting the audio delay settings didn't help. According to Marantz and Oppo's tech support the problem is because I'm using two different amps. One to drive the main speakers and one for the center.

How are the source and amps connected? Does the 2 channel preamp have a HT bypass input?

My preamp has HT bypass. The Oppo is connected to my DAC via an Optical cable

Then the Marantz front preouts connect to HT bypass input on the preamp and analog output of DAC connect to an input on Marantz, correct? If this is not correct, can you please describe the connections between the Marantz, preamp, Oppo, and DAC.
