Low output with high volume

Distorted sound at a volume of 25 or greater. worked really well before. not sure when i lost the power. it is in a suburban with bose system. bypassed the park brake sensor and fixed the overheating issues. Now when i turn it up it just starts to distort. I put the old unit in and it sounds great, so its something with the deck or settings.

Sounds like distortion is being caused by trying to amplify a low volume level from the input device. try putting the ipod volume at a medium level and try again to see if the distortion goes away/reduced

I have lost my sound from TV through the Bose Lifestyle 48 recently. All other sound sources work fine- DVD/CD, FM/AM.


Hello Sunny,

No TV model... came through with your
Bose LifeStyle home theater question...

I'm just going to mention that I have seen a couple of available configurations... depending on your signal source... BROADCAST, CABLE, SATELITE... (etc.)...

If it is Just your intention to source from the TV...
THERE (at the TV)...
It might be as simple as going into "menu" ... then move down to your "AUDIO" PROFILE.. and make sure your external speaker OPTION is showing "ON" (or "equipped")...

"
on your TV and making sure your PRIMARY volumes sources & destinations (Bose) volumes at acceptable levels... so as to not FRIGHTEN your neighborhood when the sound does come through)

No success ... comment me back with your TV signal source...
HMDI or optical outputs... (and does your AUDIO Work in STAND-ALONE on the TV... Now??)

If all else is working on the BOSE... I don't think we need to continue there...

Comment me back if you need... I'll be around!

Post comments... addendum

(I did say Menu... (twice))...

RESET , General:

**WARNING:
This operation will clear all of your customized settings.

V... depicts the volume down button on your remote
(immediately above the "menu" button).

With the set turned off...Stand in front of TV.

At the right side on the TV set... locate the power
button on the right side...

WHILE holding down the V (on the remote)
Turn on the TV POWER button on the TV.

(The TV will turn itself off, then back on again.)

Then ... V (symbol) Release the button.

**WARNING:
This operation will clear all of your customized settings...

I'll still be here... comment me back... if you need.

Hope it helps

My panasonic dvd stereo system sa-pm91d when the volume is turned above 25, it plays distorted sound, it sounds like I have incorrectly tuned a radio channel even when using the auxiliary input


Hi Gusma,
If you have Distorted sound.
    These may be the causes of the problem:

  • Make sure the speakers wires are properly connected.Check the color codes, be sure they are rightfully followed.
  • - Shorting (bare wires touching) of positive and negative speaker wires.
  • - Using speakers with an impedance lower than that rated for this unit.
  • - Straining of the speakers through excessive volume or power.
  • - Using the unit in a hot environment without proper ventilation.
I am also including a link to the User Manual. Read it thoroughly.
Best of Luck,
JP

Hello, i have a dell Windows vista and my companion bose 5 wont work.. and ive tried it in another computer and it still wont work. what can be the problem?


Is there any system to which you can connect your BOSE *and* have it work?
If not, then check that the BOSE is getting electrical power into it.

Can't get video to work so bose works with tv sound


We fixed it. We had everything hooked up right, but - stupid us - we didn't turn the sound off on the TV. Once I turned the TV's sound setting to off, I flipped the speaker switch a few times on the Bose remote, then turned up the volume on the Bose and it worked.

Bose SA2 distortion


As the distortion is on both channels it must be something to do with something that is common to both!
My guess is an IC. Check to see if it uses an IC for the main amplification. They are big with loads of pins coming out of them. Sometimes marked STK and then a number. If you find one it will have gone! Replace it with the exact part.

Bose Lifestyle 35 Accoustimass module rattles at high volume


Well to be hones 85 sounds pretty loud to me, generally the bose acoustimass module shouldnt really be distorting or crackling unless under extremely high sound levels.

It could possibley be that the speaker cone in the bass module has a slight perforation so it would distort at high levels. However other problems could be loose connections inside the unt or outside the unit. If your friend doesnt have it above 85 under normal circumstances I wouldnt worry to much about it but if there is a tear in the cone the problem could get worse.
