zone 2 is just for an extra set of speakers in another location, your sub is not attatched to that zone

When the power indicator is blinking red, there are a few possible issues. 1) The unit has overheated internally due to insufficient air flow around the unit. Let it cool down and then make sure that you have it in a well-ventilated area. (If you keep your home theater devices in a "closet", make sure that you have good air flow so that the heat from all the devices doesn't build up.)

2) The speaker wire cores are touching each other or the back of the unit. The DRA-397 will shut itself off if it detects a short of the speaker wires. Check the connections and make sure that the wires are not touching where they shouldn't.

3) An internal short or fault has been detected. In this case, contact Denon for repair.

I hope this helps.

(Based on setting up our systems, it can be easy to have a loose speaker cable.)

If you are not pressing the power button on the remote that may be the problem

Disconnect speaker wires and try to turn it on. If the problem still there you need to bring the receiver for repair it has an internal problem - burned channel or bad power supply.

Let's understand this - you have an external volume control wired in series with each front speaker set?

Can you elaborate on their electrical characteristics?
