Yes ive heard of such a thing because just randomly my sx-316 decided to do that also
and im thinkin the amp is blown. my SW channel sounds as if its shorting yet ive checked all the wiring,polarities, and used 3 dif subs on it and all are the same result. The amp is built into the reciever so you cant modify the volts heading to the sub.

Try turnind down the sub from the amp itself it might be putting out more volts than the subs input can handle check your standing wave feature to make sure the trim is not up too high

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:

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!

Pioneer receiver sx 316 shuts off after a few moments of being turned on

Mine is having this problem now.

Tried re-inserting the speaker wires.
Tried resetting before it shuts off.
Tried disassembling but solder joins are still nice.

It still shuts off soon after power up. Time to spend money? :(

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

Low volume from Akai turntable attached to Pioneer Surround Sound Receiver

If you receiver doesn't have phono inputs,you will need to buy an inline phono amplifier.Phono inputs have a built in amplifier,all others don't.Try they don't carry them,they will tell you who does.
