Pioneer VSX-1022-K with a Polk PSW 110 Sub Hookup Problem

post #1 of 7
Thread Starter 
Hello all,

I am having a strange issue with my setup and was wondering if anyone could provide some advice to fix it. My current setup is a Pioneer VSX-1022-K receiver that has two JBL ES80s hooked up to it on the front channels, serving as a 2.0 stereo setup. My video input configuration is an HTPC with a DVI->HDMI cable into the SAT/CBL input on the receiver using the Digital Coax output from my Audigy 2 ZS audio card, an Xbox 360 using component video cables (directly into the TV) and a TOSLINK Optical cable into the receiver (these are my only inputs). With that setup, I ran the Auto MCACC when I first got this system and it set everything up properly and everything sounded great.

For Christmas, I received the Polk Audio PSW 110 subwoofer. I know that there are much better subs for MSRP of this sub but my wife got this sub for $99.99, which I don't think there would be much better for that price. My problem is when I went to connect the subwoofer to make a 2.1 system, I am not getting any output out of the subwoofer during playback. I connected the subwoofer using a subwoofer RCA cable and connected the Pioneer's Subwoofer Preout terminal to the PSW110's LFE terminal (which on this model is shared with the "R" line in terminal. When I run the Auto MCACC with the sub connected, it tests all of the speaker connections and I hear both the fronts and the sub (although the sub seemed very quiet to me even on max volume), but when I go to play anything through the system, I hear nothing from the sub. When I went into the settings menu, I found that the fronts had been left at "Large" and the sub was set to "Yes". I know that the fronts need to be at "Small" to send the sub channel, so I changed them to small and the Xover to 80Hz but the subwoofer still did not output any audio channel. I have the Polk's dials set to LFE for the Xover on the sub and the volume set to Max and still nothing.

I thought that this may be due to the wrong type of audio listening mode, so I changed between "Direct", "Auto", 'ALC", "Standard", and all of the "ADV SURR" options to no avail. I thought that maybe it was not getting any sub channel audio because I am running Dolby Digital Live on my computer (which is a simulated Dolby Digital output) so my last trial was with my Xbox 360 since I knew for a fact that this would be true Dolby Digital output using its Optical output. I saw the receiver go to Dolby Digital input mode and still heard nothing from the subwoofer.

Am I connecting everything properly? If so, am I doing something else wrong in the setup or is something wrong with my components?

Thank you, in advance, for your help and time.

Bump. Anyone have any ideas on this issue?

I did forget to mention that when I unplug the sub and touch the unconnected RCA end, the subwoofer does make a simulated bass "hit" from my fingers voltage potential and that was much much more powerful than the noise the receiver was emitting during the MCACC, so I don't think the sub is faulty (although I don't know if there is a way to test this).

Thank you all.

Does anyone have anything that might be able to help me with this. I have tried, seemingly, everything and still can't get output on the subwoofer. I'm thinking that the subwoofer cable that I am using might actually be bad... Is that possible or normal? Is there a way to test the sub to see if it is at fault?

Thank you.

Try using the ADV SURR button on the remote and select EXTSTEREO. I found this will engage the sub when listening to Pandora or other stereo channels. The sub works fine when watching DVDs in 5.1 using the auto detect setting.

I did try the EXT STEREO setting in the ADV SURR and still don't get anything from the sub. I actually believe that the sub might be at fault. I replaced the subwoofer cable with a much better one and the sub still didn't output anything. Actually, at first the sub was super loud but then faded to absolutely nothing quickly. After leaving it off for a whole and then plugging it back in, it seemed like the sub was back and then faded again. I think the sub's internal amp might be overheating. Going to return the sub and see if a new one will resolve my issues.

Thanks for your assistance and I will report my findings after I get it replaced.

Just wanted to update everyone on this issue. I returned the sub for a brand new one and the issue is completely resolved. That must have been a faulty unit.

Thanks for everyone's assistance.
