I have a GTP-506 tuner/preamp and two GFA-5006 amps that are going to connect to a Niles Speaker Selector to run 4 pairs of Niles OS-20 8ohm speakers. We run three sets at once pretty much all the time when listening - the fourth set is outdoors. I'm not using the room2 or room3 outs as the speaker selector is handling the distribution.
I'm stumped as how best to wire the amplifiers to drive the speaker selector box to get the most power. Right now the two amps are bridged with one driving each channel, but I'm not sure I have the bridge switches set properly, and I don't know if I need to daisy-chain the channels to get the full 175w per channel, per amp.
Do I need to daisy chain the channels on the amplifier by adding an interconnect from channel out to channel in on the bridged channels or is that what the stereo/bridged switch on each cannel does?
Could you please send me a wiring diagram that shows how I should set this up - with the bridge switch positions indicated?
BTW - I do have the manuals but they are not clear at all on this - at leat to me.
Thank you.
