Help re running same pr of speakers off of 2 zones of multi zone amp

post #1 of 2
Thread Starter 

I have a 3 zone Yamaha AV receiver ( HTR-6295 ), Zone 1 is my AV surround sound setup which includes utilizing a pair of  '70's era large JBL Studio Monitors as rear surrounds.  Zone 2 is some outdoor speakers. Zone 3 is unused. 

 

The JBL's are capable of handling way more power than the rest of my AV speakers can handle but since they are rear surrounds in Zone 1, I cannot isolate them in Zone 1 with the controls of the AV Receiver  .  So, if I wanted to really crank those JBL speakers once in a while for some classic rock, I can't.  So my thought was if I could hook them up to Zone 3 I could use them whenever the wife and kids weren't home for a little AC/DC or Led Z while doing my chore list.

 

I just don't know if this would do any damage to the amp from cross feeding power from one zone to another.

 

So if these JBL's were wired to Z1's rear surround outputs ( as they currently are ), plus I added jumper wires to the Z3 main output, if I left Zone 1 and 2 turned off so was using Z3 and the JBL's only, or alternately for AV usage would have Z1 on only ( Z3 turned off ): 1 ) would this work?; 2) would I damage anything; 3) if this won't work, how can I accomplish this.

 

Last dummy question, if my idea above will work, if I accidentally turned on both Z1 and Z3 power what chaos would I create.

 

Note my room layout and the sheer size of the JBL's mean I can't make them my Z1 mains ( that way I could isolate them with the receiver controls ) so I desire to find another way to accomplish running these JBL's on their own on occasion.

I wouldn't do it. If you accidentally send power from both zones at once to the JBLs, that could be the end of your receiver.

Some kind of A/B speaker switch box might work, but hook it up in reverse. In other words, where you would normally connect the outputs to two different speaker sets, connect that to your different zone outputs on the receiver. Then the input on the switch, connect to the JBLs. But pick one that won't let you somehow enable both speakers at once (that doesn't have an A+B option).
