This model has a audio relay at the speakers output. When you turn the unit on there's a short delay and then the audio output switches on. It happened exactly the same with my unit. The problem is that this relay is not "closing" properly so there´s no audio coming to the speaker rear pannel conectors. You´ll find this relay inside the receiver, exactly behind the power switch. It's a clear rectangular plastic box with coils and contacts inside, make sure these contacts close after turning the unit on. You may need to take away the clear plastic box in order to have access to these contacts. Clean them and the mechanism with proper electronic fluid. Make sure these contacts are moving and the springs are ok. Hope this helps. Regards, Andy.

How do I hook up a powered subwoofer to a pioneer sx-316?

Many subwoofers accept both line level (RCA jacks) and amplified inputs (+ and - speaker terminals). The Pioneer SX-316 does not offer line level output, only amplified outputs via the PURPLE + and - speaker terminals. This means that in order to use any subwoofer with an SX-316, the sub woofer will need to accept a + and - speaker wire connections for input Your manual speaker connections are on page 11 of the manual which can be found here: http://www.manualslib.com/manual/260358/Pioneer-Sx-316-S.html#manual

Starting at the rear of the SX-316; run a speaker wire from the PURPLE + and - terminal (SUBWOOFER) to the + and - speaker input terminals on the subwoofer. See your subwoofer manual or experiment (at your own risk) with connecting the speaker wire from the SX-316 to the subwoofer's + and - LEFT only, RIGHT only or BOTH left and right speaker inputs. Do not connect wires from the SX-316 to the speaker OUTPUT terminals of your subwoofer.

Finally, adjust any variable low pass filter knob or setting on the subwoofer to the lowest frequency that your main speakers are capable of producing. If you're not sure what that value is, try setting the subwoofer to 100Hz and judge how it blends with the main speakers. If it seems a little too bass heavy and thick then reduce the setting to 80Hz. On the other hand, if the sound seems to be slightly thin and lacking weight, try increasing the setting to 120Hz. By careful listening and a bit of patience you will be able to get the sound to seem balanced and well blended.

Good luck!

1976 pioneer sx 1250 receiver has no sound from receiver to speakers

for
1976 pioneer sx 1250 receiverhas no sound from receiver to speakers

check the integrity of speaker systems,

check the receiver internal components, pay close attention to the

capacitors, possibly have dried up or swollen (age)


Check for continuity to the speaker outputs.


These may take some time, but I hope you will make it.

My Pioneer SX-780 Receiver has very low volume and distorted. Are the output IC Amps bad? They use (2) STK-0050

A little more triage would be in order before you take a knife to it. What source(s) produce the distorted sound? How about test tones? Same? It's sick. Not same? Something else is going on. Have you referred to the manual(s)?

Pioneer sx-255r can i connect 6 - 8 ohms

Yes, you can use them but be careful. These are not necessarily robust speakers. If they sound strained, back off.

I have a Pioneer Audio Multi Channel Receiver model SX-316-S and I can't seem to figure out how to hook up my TV and DVD to the receiver so that all sound comes through the receiver

DVD audio straight in from its highest quality audio output. Use the stereo audio output to run straight to the TV for casual watching through TV speakers without the Pioneer involved.

A TV is just a glorified night-light, not a sound source - get its related audio from the Cable Box, ditto the highest quality
