No matter what you do, there is only one power switch and it turns both zones on at once. But let me rephrase your question, because the answer is in asking the question right:
Anyone know how to make a Denon 2802 or 3802's main zone silent but keep the multiroom on?
Sure. Switch the main zone to Video Aux, where chances are real good that nothing is plugged in. Whenever I program a Pronto with one of these receivers, an option for both zones is to silence them so the other zone can play solo. The shutdown routine also switches both zones to Video Aux to avoid: 1.Turn on Home Theater for a quiet Sunday morning movie. 2.Patio Speakers blast neighbors with Zone 2 on Acid Rock station with high audio level from yesterday's party....
"Silence a zone" also lets you kill the sound outdoors while someone is watching a movie without turning off the receiver and thus the movie. And vice versa.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
