Kenwood 107VR rec and No vol from Sub Output w/ menu Opt On

It seems like you've tried various connections and settings to get your JBL135 subwoofer working with your Kenwood receiver, but you're still facing issues. Let's break down the situation and provide some recommendations:

1. Subwoofer Connection:
   • Using the LFE/Subwoofer Out: This is the preferred method for connecting a subwoofer. Ensure that the cable is firmly connected to both the subwoofer's LFE input and the receiver's Subwoofer Out port. Make sure you have enabled the subwoofer output in the receiver's settings menu.
2. Subwoofer Settings:
   • Gain: Adjust the gain knob on the subwoofer to achieve the desired bass level. Experiment with different settings to find the right balance.
   • Crossover: Set the crossover frequency on the subwoofer to blend with your tower speakers. Start with a conservative setting, such as 80Hz, and adjust as needed.
3. Receiver Settings:
   • Speaker Configuration: Set your tower speakers to "Small" in the receiver's settings menu to redirect bass frequencies to the subwoofer. This ensures that the tower speakers are not trying to reproduce deep bass.
   • Bass Management: Enable the appropriate bass management settings in the receiver's menu, which typically includes crossover frequency and speaker size adjustments.
4. Check Subwoofer Cable and Port:
   • Ensure that the subwoofer cable is in good condition and securely connected to both the subwoofer and receiver.
   • Try using a different cable or testing the subwoofer with another receiver if possible to rule out cable or port issues.
5. Factory Reset:
   • If you've exhausted all troubleshooting steps, you may consider performing a factory reset on your Kenwood receiver. This will reset all settings to their default values, potentially resolving any configuration issues.

If none of the above suggestions work, it's advisable to consult the user manual for your specific Kenwood receiver model or contact Kenwood customer support for further assistance. They can provide more detailed guidance based on your equipment and setup.

Hello Brian,
There is no reboot button on this unit. To reboot the receiver, simply unplug AC power for 30 minutes, then while plugging back in press and hold the power button for 5-10 seconds at the same time to reset.
Check all the speaker wiring for shorts, make sure they're also not touching the chassis of the receiver, or are not otherwise pinched or frayed. If all looks well, try disconnecting all the speakers and cycle the power off, then on again.
Try connecting the speakers one at a time until one of them shuts the Audio down. Check this speaker with a multi-meter and make sure it is reading between 4-8 ohms.
If not, the speaker may be blown and is causing the receiver to short out and therefore power the audio down.
If you still cannot get any audio through the system, then it likely has bad output transistors, or capacitor and is in need of service.

Hello Laura, your Kenwoon, does not have digital audio inputs,
Neither Fiber optic input, nor Coax, nor HDMI
only stereos, if you can connect your television, if you have analog output and enter it in your Kenwood
I am sending you the user manual of the 107VR Receiver, to observe the possibilities that you have
I hope you can enjoy your equipment
Greetings Franco Dosil

Hola Laura, tu Kenwoon, no cuenta con entradas de audio digital,
Ni entrada de Fibra optica, ni Coaxil, ni tampoco HDMI
solamente entradas estereos, si puedes conectar tu televisor, si tiene salida de analogica e ingresarla en tu Kenwood
Te estoy enviando el manual de usuario del 107VR Receiver, para observes las posibilidades que tienes
Espero puedas disfrutar tus equipos

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.

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...

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.

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.

I felt supid this morning.
I bought a high end cable for my subwoofer.... and it did not work but a regular RCA Cable did. When I went to put the cable back in the package I saw an arrow pointing one way, I turn the cable and it works great.

"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
