Re: Sounds but no bass

Check your setting for the sub first. If that doesn't pan out it is likely to be the amp.

I have a sony HTDDW7600, i cannot get the dedicated subwoofer amp to work. The fan is running on it, but for some reason the only way i can get it to do anything is to unplug the cable that goes from the...

You have a very good of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer.
.your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2) order to activate the sub woofer amplifier you need to make a selection on the surround modes while you are switching the modes of the surround you will see the speaker position on the display of receiver as well..if you do not see the sub woofer it wont be activated..Sound Field Program (A.F.D) is a good example to test it..

Hope this helps!

Additionally please follow the instruction on your user manual to activate the SUB ,as is follows..

Low-frequency (bass) signals can be directed to the
subwoofer and/or the front left and right speakers
according to the characteristics of your system. This
setting also determines the routing of the LFE (low-
frequency effect) signals found in Dolby Digital or DTS
Choices: SWFR (subwoofer), FRONT, BOTH
• Select SWFR if you connect a subwoofer. LFE and
low-frequency signals from other channels are directed
to the subwoofer according to the speaker settings.
• Select FRONT if you do not use a subwoofer. LFE and
low-frequency signals from other channels are directed
to the front speakers according to the speaker settings
(even if you have previously set the front speakers to
• Select BOTH if you connect a subwoofer and you want
to output low-frequency signals from front channels to
both the front speakers and subwoofer. LFE and low-
frequency signals from other channels are also directed
to the subwoofer according to the speaker settings. Use
this function to reinforce low-frequency signals using
the subwoofer when playing back sources such as CDs.

Hi, I cant get my bas to work with 5.1 only with my front right and front left. what channel should i use? please help

Please rephrase. "5.1" and "only ... front right and front left" are mutually exclusive. Look at manuals.

In general, bass is 'managed' by directing it toward or away from any speaker the user declares to be LARGE or SMALL, usually based on arbitrary cone sizes instead of bass handling capability. There 'managed' bass is rerouted to the presumed capable LFE/Bass/Subwoofer channel to avoid potential damage to bass-shy speakers. Therefore, if one lacks a subwoofer one has to tell that to the receiver and designate the other speakers as LARGE or the bass will get tossed in the bit-bucket

Two of the surround speakers are not working. There used to be three that were not working but I jiggled the wires around and put them in further and it fixed the problem. That does not seem to be the case...

check that the wires going into the connectors on the amp are properly stripped and then do a speaker test if speakers works on speaker test then change the accoustic settings on the amp if this does not swap the speakers cables around on amp and check if do have a faulty speaker.chance are that your accoustic settings are not set for 5.1 surround sound but for stereo this is common if your low or bass speaker is not working.

Want to connect non-bose speakers to a bose lifestyle system

this is possible, however not a very good idea.
Bose speakers are designed a little different than other brand speakers, the Equalizer built into the bose system will probably not sound amazing when you hook up your other speakers. Are you looking for more bass? cleaner highs?

if you want more bass, you could try doubling up your subs, if you want cleaner highs you could buy Bose Jewel Cube Speakers (purchased from a Bose Built-Invisible Dealer

Front bose speakers and bass module stopped puttimg put sound

If you're saying you hooked the Bose speakers directly to the Yamaha's amp instead of the prescribed way through their own bass module - they're cooked.

You need to take apart tthe sub woofer and check the connection to bass speaker for continuity. It sounds like an internal broken connection to speaker on sub woofer unit.

'stereo' speaker problems

Yer man there a load of **** i've got 2 x DV290's one for the back of my studio & one powering the front,your lucky you only had 2 **** speakers i had 4 lol.
but there is light at the end of the woofer,they have to be wired together its as if one makes the other one work,so you put GRAY & BLUE in you get BASS or hum ,you put BLACK & RED in you get HIGH or top end you put all four in you get nice mixture.
I've also had it another by mistake & it worked, i put the + & - side by side instead of top & bottom so it was RED / GRAY & BLACK / BLUE if you know what i mean.then cut the plugs off the surrounds & wired them in aswell & it's all good in de hood.
oh a tip before i go,get some rubber legs off the bottom of something or the casters off an old chair or stool & GET THEM SLAPPED BETWEEN THE AMP & THE SOUND PROCESSOR for ventilation coz Fu*"*k me they don't half get hot man!
good luck pal....later

Sounds like your original and this sub have bad amps. The amp for the sub is not the same as the amp for the other speakers. The old unit has a dead amp and this new one is on the way out. (Pulling too much current on high bass)
