New member Username: Rich75Post Number: 2 Registered: Nov-05 | I would like to have one pair of speakers double as both the rear surround speakers and the B speakers, so that when using surround sound, they would be the rear channel, and when listening to 2.0 stereo, they would be turned on or off with the B switch on the receiver. I have a Technics SA-DX940 receiver. It's 5.1, with A/B front speaker selectors. In stereo mode, both A and B can be run at once; in surround sound mode, B cannot be run. Speakers are Infinity Beta 50s (with the Beta 250 center, no sub). I could accomplish this by running two sets of cables from the receiver, one from the B outputs and one from the rear channel outputs, or by running one set of cables and jumping the B outputs to the rear channel outputs. I would effectively be creating a loop between the B and rear channel outputs, and I'm concerned that this might damage the receiver, or that it would degrade the quality of the sound. Will this damage anything? Any thoughts? Thanks for your help. |

Even that presents some risks should you get careless in your wiring. |

But the leads from the AB switch were removed, and the B position fed power to the normally closed contacts of a solid state relay, other outs to the normally open side. When switched to B position, the relay pulls, and routes the signal along the right path. Even a failed relay was foolproof. Well, you asked. |
