I have the Pio 1018 Receiver matched with an Acculine aSub. I have tried to no avail to get the sub to produce any sound, it used to just fine, now it won't.
Here's all the checks and balances I've done:
I checked the sub, the fuse is not blown.
I have verified power to the sub, both in "ON" and "AUTO" positions.
If I put the subwoofer cable slightly into the connection on the back of the sub, it produces a loud bass sound, as would be expected when the cable is being half-way inserted into the connection.
I have set my LFE on every different volume on the 1018, currently it's a +2db.
I have verified that the SW cable is connected to the "Pre amp" subwoofer output on the 1018, not the multi-channel out.
I have tested the sound on TrueHD tracks on Batman Begins Blu Ray, as well as I Am Legend. The LFE icon on the front display of the 1018 shows LFE activity (little bars going from each side of the LFE icon) whenever LFE should be heard.
I have tried other blu rays, the PS3, cable, and different audio formats including Dolby Digital, Stereo, HDMASTER, NEOstuff, etc. Everything.
I have set my speakers to LARGE and my sub to PLUS. I have tried every variation known to man beyond that, including speakers to SMALL, sub to YES, etc.
When I run a Manual MCACC(a), the SW channel produces no noise, whereas the other speakers do produce the expected noise. I cannot perform an auto MCACC, because my microphone for the process is lost.
I have confirmed all cable connections, tried different connecting wires from the amp to the sub.
I have tried all forms of adjustments on the volume knob and the frequency knob on the back of the sub, and currently they are set to "max volume" and approximately 100Hz.
I did all of this, and then reset my 1018's settings, and started all over, and there is still no LFE, where there clearly should be, especially since the LFE icon on the front display is indicated that the LFE channel should be producing sound.
I have tried the Phase adjustments. I have no Zone 2 set up.
I have tried connecting the subwoofer cable (and other cables) both singly to the L channel, then the R channel. I have also tried Y cables to both on the back of the sub, although this was never previously necessary.
The rest of my setup includes a 5.0 Energy RC10 fronts and center, Sony Surrounds, Pioneer 51FD Blu Ray Player, PS3, Pioneer Kuro 5020 TV. Everything works great except for the sub.
My thought is the sub is toast, but how can that be? The sub produces tremendous bass when the cable is 1/2 way inserted into the R channel on the back of the sub. The power is working. The cables have all been tried with other cables. The fuse is not blown. The 1018 indicates the LFE is being sent via the PREAMP out subwoofer connection.
I hope that someone might have some insight. I greatly appreciate it!
**** ADDITIONAL INFORMATION:
I just went and looked at the back of the sub, which was set to "AUTO" power, not "ON". The light which is normally GREEN was RED. This gives me a hint. I'm thinking that for whatever reason, the sub is OK, it's just not receiving an LFE signal from the 1018.
To confirm, I am currently using a Monoprice Subwoofer cable, 5 footer. I have tried other "Red and White" cables too, to no avail. I have confirmed the connection from the subwoofer to the 1018 PRE AMP Subwoofer OUT is how it is all connected. So, short of trying a 4th or 5th cable (which I know the others work, because I've tried them in other usages), how do I get sound from the 1018 to the sub?
Thanks in advance for any help you might have. Cheers!
