Kenwood 107VR rec and No vol from Sub Output w/ menu Opt On
I have an older Kenwood 107VR receiver and it has been working without any issues. Recently my power subwoofer that I have connected to the Subwoofer pre-out RCA connector on the back of the connector does not appear to be putting out a signal. I have verified the Sub On selction is on from the menu selction for those modes that would use the Sub Out. I also verified that the volume for the Sub is at +2db from the menu. I have connected the Sub woofer to the Tape 2 Monitor Out just to verify the Sub woofer is operational and it is. Does this mean the Sub Out channel on the receiver is bad? Is there an internal fuse within the unit that may have blown that can be repaired? If so, do you have any guidance as to what to repair / replace?

In the setup menu are the speakers set to large or small? On some receivers if you have it set to large all the bass is directed to the right-left fronts. On my pioneer receiver if the speakers are set to large the sub-pre-out only works if the receiver is in a surround mode, if its in stereo mode and the speakers are set to large the sub-pre-out is dead. If the speakers are set to small the sub-pre-out works all the time. Also, some receivers won't send a signal to the sub-pre-out if there is no LFE discreet signal info from the dolby digital or dts bitstreem. For example I have several older dvd's that light up the L C R SL SR icons on my receiver, but don't light up the LFE icon. I have other older dvd's that just light up the L and R icons meaning they are only recorded in stereo like a vhs tape recorded in dolby surround. In my basement I also have a kenwood dolby digital receiver. I've noticed that when a dvd only lights up the left and right icons the pioneer will automatically switch to dolby pro logic surround. The kenwood will only send the signal to the left and right fronts (stereo). If I manually switch it (kenwood) to dolby pro logic I'll get sound from all the speakers just like the pioneer, but it does'nt do it by itself. Most receivers that have a tape monitor won't work in surround mode with the tape monitor on. The pioneer will let me use the tape monitor with dolby pro-logic but won't pass through a dolby digital signal with the monitor on. Hope this helps.

Had you bought the 106 version that has a subwoofer out socket. Some subwoofers have options for connection by speaker terminals. If you haven't bought the subwoofer yet check with the seller to make certain you can connect it via speaker wires. Otherwise you would be better with a non powered one.
After making sure that your subwoofer is receiving power, as most models have their own amplifier, make sure that it actually is turning on. There is a possibility of a faulty power switch. Lets rule that out first. Once the switch is on and the proper power connection is verified, turn your attention to the setup menu on your receiver. Navigate to the LFE/Sub output level. Adjust it up all the way. Then navigate to the crossover setting. Turn it up all the way. If the subwoofer also has it's own control panel including a crossover, turn that up all the way as well. Then with an input on the receiver that has a subwoofer output set up such as for DVD, play some audio. Or likewise you can also use the receivers' test tone capability that will pan each channel individually with a wide band pink noise signal that also includes a signal sent to the subwoofer output.
If this procedure does not produce results then send me a message including your subwoofer model and your observations of your systems' operation.
Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.
Things You'll Need:
* Amplifier * Speaker cable * Extra subwoofer
Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.
Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.
Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.
Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.
If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..
Yes. It needs to know you have a subwoofer or it won't send low frequencies out to one. Then you have to calibrate its level to match the rest of your speakers. Hit the SETUP section in the manual (available at retrevo.com).
"Sub-woofer output not working" problem, and notify you when a new solution is offered. Press the setup key on the front of the receiver Select the subw setting Move the multicontrol knob until the sub woofer is on Turn off the receiver and turn back on- the subwoofer should be on The operator manual can be downloaded on the web site--- free http://www.retrevo.com/support/Kenwood-VR-507-Receivers-manual/id/480ag219/t/2/
you have to reset the receiver, i had the same problem, works now, it's great, should be in the instruction booklet. I think it was, hold the power button while you disconnect it from the wall, not too clear but check the booklet in resetting system
