Question about Kenwood KR-X1000

Receiver only works in Stereo Mode and won't allow use of subwoofer

When selecting Dolby or THX modes the signal turns to garbage within a short period. I will get correct signal to two speakers in stereo mode. Can't use the subwoofer for long before the signal goes bad for it even in stereo mode. Sounds like a main signal processing chip gone bad or something. I'm reasonably handy but not much of an electronics repair person. I'd appreciate any tips on how to repair. Thanks

That sounds about right, about the audio processor IC most likly being the culprit. To repair this, a test tone should be inserted into the unit, and using an ocilliscope to trace the audio waveform through the circuit, and see where it craps out. There could also be a regulator componet from the power supply that is going out after start up and becoming intermittant. Sorry to say in this case there is no wasyy fix unless you have a schematic and the proper equipment. Time to take the unit into the reciver repair Place. Good Luck

Our denon 1708 only play on stereo mode,no sound when it select on 7 channel.. crackling on dolby. what is the problem on that receiver? please help

The surround sound outputs outputs ic's in the remainder of the system have opened, or there is a short in the speaker wiring, check to make sure that is not the case, if okay! you will need a repairman to assess the situation.

I hooked up my system and only the front 2 speakers and the SW work. How do I get the others to work?

You're in Stereo mode.

Try three things:

1) See if your receiver is in Stereo mode.
2) You can change your audio preferences from within your DVD menu from Stereo to surround.
3) Change receiver and dvd audio menu options to Dolby ProLogic surround.

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

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 Panassonic SA-XR50 Receiver is not producing surround sound from either of the Optical imputs from the TV or DVDR Both outputs are stereo L and R + subwoofer How do I rectify this What settings should I...

First enable the surround sound mode for the selected input and verify that the media playing is recorded in some mode of surround sound.
You can however, acheive surround sound from 2 channel sources with dolby prologic or prologicII sound processing, or other proprietary modes that your receiver might have from the manufacturer.

RCA RT2280 surround sound mode button wont select 5.1 dolby digital mode.

I had the same problem and this is what I did to fix it. Assuming that all of your equipment is powered on, (tv, blu-ray/dvd, rca receiver) you'll need to go into your dvd players audio menu and select the dolby digital audio.
Once you do this, the digital signal is sent to your receiver from the dvd. The receiver should automatically set itself to the dolby digital preset. If it doesn't, press the surround button until you reach it. I found part of this information here. And the rest was personal experience.
Also, it depends on if the disc format is in dolby 5.1. I hope this helps you.
