Either the sub woofer speaker or the sub woofer amplifier section circuit has the fault. Contact any service technician to make diagnosis the faulty section. If you wish to get some details; check the site linked here. Pull up older posts.

In my RCA home theater system, the rear and the center speakers are not working. I tried very hard and did everything but no use. please help me


Make sure every cable is connected to the right speaker. Then make sure you have the Receiver on the correct setting. Not stereo...Dolby 5.1 surround or the like. Make sure you are playing from a DVD or a source with 5.1.

Prima HT 8104 home theatre


in the 3D processing turn on the Pro Logic and the for the mode as well set it to pro logic.
it simulates 5.1 surround.

this is what I did and it's decent. Other way would be to run the system through a amp/receiver that supports 5.1 surround.

Latest model surround receiver for bose 901 speakers VI


I can think of no reason any amp pushing 120 watts would not work with 901-VI's. They're very efficent and will probably play louder and cleaner than you would ever need. As I recall, my old series IV's have no maximum amplifier rating specified, but I did blow up a bridged Carver M-400 Cube (pushing 400 watts to one speaker with a DVD-Audio of Yes - Fragile cranked dangerously high) with them. I'm convinced my speakers are indestructible in any home application.

Keep in mind that whatever you decide to use as your control/amplifier section, a pair of 901's need a dedicated stereo amplifier. I suspect you're thinking surround sound so a receiver with separable preamp/amp channels, due to the Activbe EQ, would be needed and as far as I know they don't exist. A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver and the 901's amp channels. My receiver controls everything and just drives the Center and Surrounds.

Modest amps would work but at very loud volumes may go into clipping, which is bad for any speaker. 120 clean watts is good. I'm using only 110W for mine.

A Carver M-200 is a fine, efficient amplifier that would have you cooking just fine (2x100W).

Best amplifier for bose 901 VI speakers


By all-in-one amplifier that handles the surround I think you mean all-in-one receiver or preamp. Amps are just big dumb muscular power supplies for speakers.

The source control and digital decoding could be handled by a modern AV receiver with multichannel analog outputs for driving separate amps or you could get a digital AV preamplifier/control unit functionally like this Adcom. Prepare for sticker shock.

http://hdtvdreams.com/Adcom-GTP-870HD-7.1-Multi-Channel-Processor/Preamplifier-GTP870HD.aspx

Understand that EACH PAIR of Bose 901's will require its own DEDICATED two channels of amplification AND someplace to jack in its Active Equalizer - between the line level source and the power amp.

Conventional speakers can probably run off the receiver's amplifiers since they don't/can't/must not have the Bose Active EQ in line with them.

Having a single pair of 901's plus a passive subwoofer or two in the same room for accurate 6- or 7.1 surround would require at least four stereo amps or some combination that adds up to 8 channels.

In my own system I have a Pioneer VSX-36TX Receiver (with 5 potential channels of amplification for Left, Right, Center, two Surrounds) doing light duty as the control and routing center but ONLY driving the Center (two Kenwood 777's) and Surround speakers (Bose 301's). I have a Carver 5-channel amp pushing the Bose 901 Front speakers (100Wx2), two dbx Subwoofers (110Wx1) and the Bose 301 Rear Surround speakers (60Wx1).

You could probably get by with a powerful 2-, 3- or 4-channel amplifier to push the 901's and subwoofer(s) as I did. It's the cheapest way out if you get a decent AV receiver. Once you set up the levels and delays the receiver does all the thinking and controlling for you.

Only sound from Direct and Stereo settings on Denon AVR 788


Other listening modes (dolby, dts, neo6) are decoded from digital signals.

Direct will relay your only your discrete analog inputs - so if you want to use your AVR as an amplifier for those channels, you'll need to supply an input signal in a different manner.

Sound problem


Hi,

I have a creative SoundBlaster LIVE! 24 Bit External Sound Card and this annoyed me for weeks.

depending on your surround sound reciever depends on the solution.

i have an Acoustic Solutions surround sound system with coxial and optical inputs, aswell as stereo red & white jack inputs.

not knowing the method or connection your using makes it difficult to give you a single solution so i'll list a few.

The soundblaster software shoudl include the Creative Audio console with all sorts of effects, one is CMSS (CMSS-3D) Stereo widening which is still stereo but gives a surround sound effect.. but i'm guessing you payed for 5.1 and you want 5.1 onto the next part

5.1 surround sound can only be produced when the actuall audio your playing contains 5 channels of audio, for example you cant play a stereo song in 5.1 surround sound without some sort of hardware or software sound manipulation. Luckily my surround sound system has Pro Logic II built in and some other effects which convert a 2.1 signal to a 5.1 signal and it works brilliantly. I'm not sure of a software alternative.

setup for your soundcard will be different under XP and Vista also, but there should be a properties option for your sound device where you can select your speaker setup such as headphones, built in speakers, 2.1 speakers, 5.1 speakers, 7.1 speakers and you should be able to manage this from the creative software.

If using Coxial / Optical or SPDIF under vista you MUST set the playback device as SPDIF, at least you have to with my sound card and drivers and seems to be a limitation of the actual sound card drivers for vista.

Personally i was looking forward to hearing the windows login melody in 5.1 surround sound too, but this doesnt happen.

Infact i find that almost all programs bar a few will not play Dolby Digital or DTS 5.1 surround sound via any or my output options hence the next solution..

if you have the 5.1 sound but winamp simply just plays it in stereo try the following.

You need to use DirectSound Output:

Preferences (Ctrl-P) > Plug-ins > Output > Select "DirectSound Output"

That should work in most cases, but if not, then:

Checkmark: "Allow hardware acceleration" in DirectSound Output config,
and make sure your sound card/chip is selected as Output Device.

Note that any changes will take effect only after playback is restarted.
In some cases, a Winamp restart is required.

If that doesn't work make sure you have the latest version of DirectX
(v8.x or higher is required)

Winamp 5.25/5.3 and higher:
For actual multi-channel files (ie. aac/wav/ac3/ogg/wma files encoded in 5.1ch surround, as opposed to standard 2-channel stereo mp3's), you need to checkmark "Allow surround sound" in 'Winamp > Prefs > Playback' for the music to play in its original 5.1 channel format (Note that this setting is checkmarked by default).

Windows Vista:
In addition to the above instructions, Vista users will also need to go to:
Control Panel > Sound > Playback tab > Speakers > Configure:
Select: 5.1/7.1 Surround.
Then:
Control Panel > Sound > Playback tab > Speakers > Properties > Enhancements tab
and checkmark "Speaker Fill"

Hope this helps

Polk Audio RC55i In-Wall Surround Speakers (can't hear whispers)


I'd make sure that the receiver surround mode is set for one of the digital settings, such as Dolby Digital or DTS, and make sure that you have the center channel level adjusted to a level similar to the other two front channel speakers. I've seen/heard this happening when using dolby digital material & having surround set on something like 'hall' or 'stadium' or dolby surround, where only 4 channels are used & the amp has to 'mix' sounds to the left & right front speakers. It'll often sound like the actors on screen are talking out of the bottom of a barrel, with a hollow & tinny character to the voices.
