Two Tsi500's and a vintage Sony STR-6800-SD Receiver Question

KRobinson

Alright, I just want to make sure I'm hooking everything up right because when we hooked it up at my old place everything sounded great for about a minute and then static started playing over the music and the thing eventually shorted. The back of the receiver has four different labels for wires. Speaker A, Speaker B, Speaker C, and Speaker Impedance. Each set (A, B, C) has four inputs for wires (two red, two black). So my question is since the tsi's are bi-wired should the top sets of wires from each tower go into speaker inputs A and the bottom sets of wires go into speaker inputs B? Or is this wrong?

Before you do anything else, you need to have the 6800 checked by a competent vintage tech, and repaired if needed. While this is a great vintage receiver, it's also about 35 years old. Sounds like it may be having problems. Trying to drive speakers is only going to destroy the receiver, or your speakers, or both.

If it was working fine before, sounds like you connected something wrong. At this point, don't worry about bi-wiring, put the plates back on the TSi and just connect them to one set of speaker outputs....A B or C, not both, not two....just one.

Did you even remove the metal jumpers/plates from the binding posts of the TSi speakers?

The impedence should be set at 8ohm.

Ditto, connect to one set of posts in either A,B, or C. Make sure the jumper plates on the back of the speakers are still there. If you get static in the speaker A position, move to the B position, but that only means the receiver is begging to get fixed, or time for a new one.

Welcome to Club Polk!

Doro and tonyb, etc. have your back. That Sony is a nice looking piece, 1978 80 watts x 2 RMS, pretty heavy. But that is also old enough to need a tuneup, new caps at the very least if they've never been redone.

It certainly has enough power to get a set of TSI-500s going.

Good Luck!
