I know this is probably simple but I am struggling getting sound to my auxilliary pairs of speakers, from my 890 "properly", I think.
My setup is:
- 5.1 main room
- 3 pair of speakers throughout the rest of the house, connected through impedance matching vol controls (home-runs, not daisy-chained) and then connected to an inpedance controlling speaker switcher. (probably overkill on the double impedance controlling, I know...but I can always turn it off on the vol controls)
So - if all I want is the same audio that would be on the main 5.1 setup to come through the speaker switcher to go to the speakers throughout the house - how do I do that simply?
My first attempt was to set the Bi-Amp setting to Front B Bi-Amp, and then connecting the speaker selector to the Surr-Back/Amp Assign terminals. I got no sound from this setup. My theory here was to take the extra amps I don't use and send their power to the Surr-Back/Amp Assign terminals.
My second attempt was to move the wires down to Speaker B terminals (still in Front B Bi-amp mode). Now I do get sound. My theory here was maybe I am sending the extra 2 amps power to the Speaker B terminals. I thought this was good-to-go until reading the manual again today, which has me thinking that my Front B Bi-amp setting is doing NOTHING to the Front B terminals, and it's actually just sharing the same main 5 amps to power both Front A (part of my 5.1) and Front B, which I know is bad for the receiver, since I'm not just running one pair of auxilliary speakers (although, as noted, they are impedance controlled). Can anyone clarify around what this current setup is ACTUALLY doing, and if it's what I want or not?
My new thought is to change the Amp Assign mode to Zone 2, and go back to using the Surr Back/Amp-Assign terminals to connect the speaker switch. My understanding of the manual is that this will then use the 2 extra amps in the receiver to power those terminals, and therefore my speaker selector. I believe I can still use digital audio sources if I do that, and control the volume through the receiver easily. I NEED to use digital audio source, since 99% of what I want to listen to through the house speakers is from my computer, which uses an Apple Airport, outputting through Optical.
Related to the zone 2 option, I realize it's an option to use Zone 2 setting and hook an external amp up to the pre-outs, however, then I know I CAN'T use my Apple Airport optical digital connection, basically making all this useless for me.
So...I know there's a few questions here:
1 - Why didn't my Front B Bi-amp setting with selector connected to Surr Back/Amp assign terminals work?
2 - What is actually happening in my current Front B Bi-amp setup with selector connected to Speaker B terminals?
3 - Is the Zone 2 using Surr Back/Amp Assign terminals a better choice and will it work with my digital audio signal?
4 - Confirming there's no reason to even consider the external amp zone 2 pre-out method (which probably stresses the receiver the least), since it can't play anything coming on from the Apple Airport digital optical?
