Technics SA-6000X help

[jmahun]

I'm a bit confused on how to attach speakers to my Technics SA-6000X.
Photo 1 shows the speaker terminals on the back of the receiver.
Photo 2 shows how I hooked up two speakers for stereo; sound output was fine.
Photo 3: is that how 4 speakers would be attached for quad? Red for the front R/L speakers and yellow for rear R/L? I've a service manual pdf but it does show this clearly and I don't have an owners manual.

Your diagram looks correct, following the silk screen info.

first time I've seen that type of hook up coding......but it's obvious to me that stereo hook-up uses the top set of both red for left/right, +/_ as marked.

for 4 ch the circled red is for front speakers (conventional red+, blk _) and the circled yellow for rear speakers (conventional red/blk) Chuck

Hook up in stereo is a "bridged output". In 2 channel mode, the rear channel amplifiers put out and inverted (opposite polarity) signal which when hooked to the return of the speakers, yields increased output. Quite common in 2/4 channel receivers in the70's. Bridged mode increases the loading on the amplifiers - its why the4channel hookups say 4-16 ohm but the 2channel mode says 8-16 ohm.
