A rookie question re two amps, one pair of speakers
@imhififan how is that not good? You need to be able to switch A/B to disconnect the amp not being used. Unless I missed something...It'll be fine if your careful, and make sure you switch one amp out before you switch the other amp in. Never have both switch in at the same time. Cheers George |
Hello everyone, I hope someone might still be paying attention to this old thread. I've been scanning through a bunch of posts/threads about possibly connecting two amps to a single speaker...in my case for comparison of a Denon POA-2200 + Denon PRA - 1100 combo VS a NAD C372 integrated amp. I have no switcher unit available...all I have is the A+ B inputs of either Amp. I am not clear on whether or not it's possible to use these switchers as a sort of substitute for an Amp A/B switcher. I don't mean using the switch to cycle between amps. I just mean using the switch to stop either amp from trying to driver the other's output stage, by turning off the A or B terminals of the amp not in use. Basically I am wondering if those A + B speaker terminals can be disabled effectively or is it the same as just turning off the HT receiver, the other amp will still detect and try to drive the output stage of the HT receiver. |
I just recently configured my system in the way the OP descibed. It can be done safely. My solution was to use an old Adcom speaker selector box, disconnection everything internally and installing a break before make switch along with some really good speaker wire. Total cost to me was about 8.49 for the switch since I already had the rest. Easy project. Be really really sure none of the wiring is shorting across poles on the switch or puff the dragon comes to visit. |
