How do you sync the output of Zone 1 and Zone 2.

There is about a 2 second delay between Zone 2 and the main zone when playing a CD. I'm using an Arcam universal DVD player and an Onkyo TX-SR875--I am not using the internal amps of the Onkyo. I have the two speakers in Zone 2 bi-amped with four Marantz mono-blocks. The input between the Arcam DVD and the Onkyo is HDMI and also an optical digital and this doesn't make any difference in the audio delay.

I'm using a Niles 8 pair impedance matching selector for my house. 5 zones off 1 amp and main zone off the Denon 395 multi-room receiver. I honestly never notice any delays from room to room. This is thousands of feet of runs.

The only way to have the 2 zones in sync is most likely to have the amplified with identical connections and amps. You need a multizone pre-amp with matched amps for each zone.
Even then, you won't get "exact" unless you are careful with matching interconnects and speaker wire lengths.
Finally, you will probably want to use matching speakers too.
Then, you still have to worry about the delay with you running from room to room to compare...

Should work much better using all internal. The other option is using the Marantz (better amps) for both zones with an a/b speaker selector?
