Use whatever TV sound output conforms to your receiver's input. If an optical or coaxial digital sound output is available, that is the way to get 5.1 surround sound through the SA-DX1050. But you have to assign the correct input (COAX, OPT1 or OPT2) to the selector (TV, DVD, CD). See pp 12-13 of the operationg instructions for D-Input instructions. If you don't have the manual you can download it at

SOURCE: Technics SA-DX950 surround sound problems

The most likely culprit here is the output protection relay. The contacts are a little corroded and the higher volume "jumps the gap" temporarily "cleaning" the contacts. The relay should be changed. I don't have the manual with me, but the following relays are in the unit. One of them is the speaker relay:

Part # Cost
RSY0054-C $12.63
RSY0040M-0 $ 5.89

SOURCE: Digital surround mode not putting out bass-RX-6022V

On the unit, just left of the volume control there a "adjust setting", cycle through the modes until you SUBWOOFFER and then press CONTROL UP or DOWN to make it say YES. I have no idea how it switched to NO. Probably with my remote, but some time did pass and I'm happy I got my Bass back. Quantum of Solace sounds great.

SOURCE: Replacing a Surround Sound System Receiver

the difference is the "same speaker connections"
the front and rear will connect the same but the subwoofer is amplified by the HT75 , and the HE75 does not have an internal amp for the subwoofer speaker , only a "pre output"(has to be amplified)

Denon receiver not working surround output

If everything is connected correct, the only thing I can think of, is you don't put in a surround signal. If you only feed 2 way stereo, only two speaker will work. Also if you switch to stereo, the other channels will stop working. Check the cables, the settings and the input.

No surround sound in TV mode

Surround sound will only work if the source signal is coded as surround. Many older TV broadcast programs are stereo only. If your surround sound is working with a DVD or blu-ray then the broadcast source is the problem

CD's and FM radio are created in 2 stereo channels. To listen to them in Surround, artificial processing has to take place in your receiver, so artifacts and fading are quite common when you do this. When you turn the surround off, your stereo is processing the information properly and it will sound right.
