Pioneer SX 316 Operating Instructions Manual Connecting The Speakers

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!

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? :(

Did you try a search engine "pioneer SX-316 manual"?

http://audio.manualsonline.com/manuals/mfg/pioneer/sx316s.html

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

1. Switch the reciever into standby.
2. While holding down the TONE button, press and hold the STANDBY/ON button for about three seconds.
3. When you see RESET? appear in the display, press the ENTER button. OK shows in the display.
4. Press SETUP to confirm.
OK appears in the display to indicate that the receiver has been reset to the factory default settings.

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 Crutchfield.com.If they don't carry them,they will tell you who does.
