Question about Kenwood 107VR

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.

My Kenwood 107vr turns off about 3 seconds after I turn it on. What could be wrong with it and how can I fix it?


Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

My kenwood kr v1074 reciever doesnt seem to do the job of my other reciever.....my sub is connected threw the red and black ports tried em all and my speaker just remains low volume even if i have it full...


You shouldn't hook things up and guess how they work.

BTW "KRV1074" doesn't bring up a valid link anywhere in the universe except your request.

Try finding the manual here...

Sub woofer output port does not seem to work on my kenwood VR 407, checked sub woofer on another system - works fine, any easy solutions?


Is the 407 set up to drive the unknown sub. It's not just plug n play.

The manual will guide you, around page 15. Also refer to your subwoofer manual. Try retrevo.com for that one.

My kenwood 107VR keeps turning off on its own, after about 3 secs it shuts off and the light blinks.


If you are sure your speakers are good. This unit has a protect circuit keeping the unit from turning on. This recevier uses an ic instead of output transistors. A ic incorperates transistors,resistors,capactors in one assembly for size and costs. There is a number right on the front of the ic ,you can go on-line to buy the ic is is fairly easy to put in as long as you can desolder and solder in.

YAMAHA AV receiver RX-V861 I have the message 'Vol-fix' appearing on Zone 2 and no sound. This was working fine until then


Setting the RX-V861 remote control to operate Zone 2:
  1. Using a ballpoint pen or similar object and press the [CODE SET] button RX-V861 remote control. The[TRANSMIT INDICATOR]on the remote should flash twice.
  2. Using the [NUMERICAL KEY PAD] on the remote and key in 9992, the [TRANSMIT INDICATOR] should flash.
Assigning the receivers internal amp for Zone 2:
  1. Set the remote control selector to [AMP]. (Located to the right of the volume buttons on the Remote.).
  2. Press the [SET MENU]button on the remote control.
  3. Arrow down to Manual Setup and press the Enter button on the remote control.
  4. Arrow to the [SOUND MENU] option and press the [ENTER] button on the remote control.
  5. Arrow to Speaker Set and press the [ENTER] button on the remote control.
  6. Arrow to the EXTRA SP ASSIGN and select ZONE2
  7. Press the [RETURN] button on the remote control to exit out and return to the Manual Setup.
NOTES: There is an option for setting the Maximum Volume and Initial Volume in the Zone Set menu.
  • Max Volume: This is an optional feature but isrecommended to prevent the accidental change in volume levels thatcould damage the speakers and receiver.
  • Initial Volume: This is also a great feature that would seamlessly start the volume level for the second or third zone at the desired level.
We do not recommend using any Speaker Selector boxes to enable more than the recommended number of speakers per terminal.
Controlling Zone 2 using the RX-V861 remote control:
  1. If the Main Zone on the receiver is on, press the [POWER BUTTON]down and while holding that button down press the [PHONO]/[**] button on the remote. The [TRANSMIT INDICATOR] will light up.
  2. You will not be able to use the following buttons on the remote: (Pressing any other button will cause the remote to exit Zone 2 mode. [POWER], [STANDBY], [VOLUME], [MUTE] and the [INPUT SELECTOR] buttons [DVD], [CD], etc.)

Cant get bass, fuse is fine


You don't say if you've configured the Receiver to know you have a subwoofer (under Multicontrol - SUBW YES). Unless it knows about the Sub it won't send anything out that single "preout". You can get an RCA splitter to run that single output to both inputs in the Sub.

Just as an experiment, temporarily run one a pair of cables from the REC OUT to the Sub's inputs and tune an FM station to prove the Sub amplifier is alive. If it's still silent, it's dead. If there is sound (muffled) you need to go back to the Receiver to figure out why the Sub Preout is signal-starved.
