Yamaha receiver with 2 or 3 pairs of spkrs in zone 2?

[newz54]

am about to buy an RXV 757 and am wondering if it can do what I had planned. The plan is to have the unit in the den supplying power to 5 speakers in a typical surround system. I would like to send audio to zone 2 which is in ceiling speakers in two other rooms. The zone 2 speakers are tied together with speaker volume/impedenance matching controls. It appears using zone 2 for the in ceiling speakers would be safest as we wouldn't have impedance problems if we wanted to listen to music in both locations (den and in ceiling). The product manual saying 16 ohm speakers are required when you play speaker a and b. Is there a better way to do this? Can I send the same source audio to both areas?

What about using the den surrounds with the in ceiling speakers when I way to play background music?. So I would have the surrounds doing double duty.....acting as surrounds for 5.1 audio and also part of the in ceiling house speaker system.

btw....I just got an email from Yamaha saying that the zone 2 would overload if more than one pair of speakers were connected. Even with impedanance matching???

It may also depend on the IM/VCs. Niles offers impedance magnification so that 2-8 ohm pair load like 1. Are you planning on running through a hub or speaker selector box?

Zone 2 connections

The easiest was to connect the Zone 2 speakers on your receivers is through the assignable zone 2 amplifier. Your receiver has an assignable amplifier that can be used for the surround back speakers (7.1) or zone 2 speakers. Using the the impedence matching volume controls will cause the receiver to see an 8 ohm impedence, even though 2 or 4 sets of speakers are connected. Just make sure the jumper is set on each control.

Concerning 2 channel background music in the den, your mains should provide this while the same (or different) music is piped to zone 2. Another mode on your receiver is to send the stero music to all 5.1 sepakers in the den.

If you really want the sound out of only the ceiling speakers in your den, you would have to connect the surrounds to the surround speaker outputs AND the speaker B outputs via a speaker selection switch.

The speakers are connected by niles controls in each room. No hub is needed. We will need to turn down the controls in the rooms where sound it not needed.

Thanks for the ideas. Yes, the niles does make the impedance of the 3 pairs as just like one speaker. So given a modest volume, the zone 2 internal amp should power those speakers. I got a response to the question from Yamaha. They don't recommend connecting more than one pair of speakers to zone 2. When I pressed them about the impedenance matching volume controls....they said it would work but that the receiver wasn't designed or that.
