Dumb lo-fi question.

I guess I wonder why there are two sets of outputs on a unit of that vintage? Is that a holdover from the old idea of "quadraphonic" sound?

@falconquest ..two sets of area, maybe on the back deck and the main listening area?

falconquest,

Many amplifiers, and I guess receivers, from late 1970s and early 1980s had two sets of speaker outputs. Such machines usually came with many buttons on the front plate, too. As for the reason, it was probably what mental just mentioned. Two different zones/areas. Idea of Sonos and similar, but with limitations of technology that was available then.

These days, there are still amplifiers with two sets of speaker outputs. Not majority, but they are around.

n80,

Now I understand why you are not letting that receiver go. It is a pretty piece.

As far as technology goes, others have provided much more explanation than I could, so I would just like to emphasize to pay attention to speaker impedance. Usually, in your case very likely, there is a note just under terminals "A or B 4-16 Ohm, A+B 8-16 Ohm"

glupson, good catch. I never noticed that. My only real interest in this was possibly putting a couple of small towers in the middle of the room and my existing Bose 2.2s on the flanks. Totally unnecessary for a room that small but just a thought. Given the limitations of the receiver I have no intention of doing that now.

As a side note...I mentioned this in another thread...a while back several of the pots would cause static and distortion when turned, particularly the volume and I was about to toss it when someone on another web site mentioned a spray for pots and terminals and such. I bought some and opened up the receiver and sprayed the various controls and now everything works perfectly. The only thing that does not function is the tiny light on the channel slider so to change radio stations you have to look very closely or get a flashlight out. The inside is pristine. A miracle since this thing went to college with me in the balmy south in rooms with no A/C for 4 years.
