I am not getting sound out of all speakers. I have the Bose Acoustamass 6 speaker surround set up and all has been great up until now-sometimes I get sound and then next time none

No you can't. The AI Answer Bot Raja Azeen is incorrect in his guess. The Bose Accoustimass has a surround sound processor, but you are only using the speakers. The Denon receiver is collecting the signal and that is already an amplifier and then you are pushing it into the Outlaw amp and pushing that signal further and into your poor speakers. Stereo is the best you will get through 4 speakers but not the phased processing that you should get.

The setup is possible, but with several compromises. First off, to use the active equalizer, you'll need to insert this into one of the 2 channel AV channels limiting your listening with the equalizer to stereo only. The acoustimass subwoofer acts a driver/power regulator for the little cube speakers. It probably will not be able to drive the 901s at the correct level when attached to the Acoustimass unit as front left/right speakers. You could try running a dedicated set of speaker leads to the 901s which may work and still allow surround sound, but you'll lose the equalization capability on the 901s.

If the unit is around 5-6 years old or less, you have a bad Rotary Encoder. It is an input to the microprocessor IC(a computer within your Bose). If you would like to inquire about repairing your Bose, please visit me at my website, audioserviceclinic.com. You may contact me directly from the site.

Yes, ur setting needs to be changed. On fliping the settings u will realise in one of the modes mostly the surround mode the speakers will work.

Thankyou
Appreciate a good rating from you..

Need to know the model no of the Polk sound system to assist.

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.

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.

Are you useing a digital coaxil cable? or optical cable?(you will need one of these connections to get 5.1 surround!) the white /red rca jacks will not do the 5.1 surround! (back speakers)
Please rate response!

The echo you hear is the audio delay between your TV speakers and Bose speakers. Muting (or lowering the volume) on the TV will eliminate the echo. Some TVs have a setting to turn of TV speakers entirely, allowing you to listen to your TVs audio strictly through your Bose system.

Hi when you turn on check all your speakers work check connections make sure the wire has no stray strands touching the fault could be in the sub unit this is possible / or your speakers one or more could have gone short circuit due to exessive volume thats if you play loud. Had a party lately .Just joking .Regards kirk
