Here's the Manual
Good luck!

There are a number of configurations for a mixer like the 1832, the most common are PA system and Recording system. There are Main output jacks which carry the mix as summed in the main faders. These in a PA system would feed the pa amplifiers which drive the house speaker system for the audience. These connectors are XLR 3 pin type on the rear, intended for professional pa amplifiers which use balanced +4dbv line input level. Amplifier which have 3 pin XLR connectors for input signals can accept that high level signal. For home style HiFi amplifiers, the signal level is nominally -10DBv and balanced or unbalanced signal lines with 1/4in diameter phone plugs which are connected to the mixer by way of a second set of Main output connectors which are 1/4in phone jacks. Use whichever amplifier input level your amp has.
If you are not using it as a main PA house mixer, but using it for recording, the main output connectors go to a 2 channel recorder or computer sound card recorder. The power amp and your monitor speakers are connected to the connectors labeled "Control Room" (CTRL Rm). These output are useful for recording because the signal through the mixer can be monitored from several buses, Solo, main mix, selected by buttons provided. The buttons only affect the signal heard through the control room monitors, and not the main output which only sees the main mix so selecting "solo" does not interrupt the signal going to the recorder while the engineer in the control can be checking other signal paths through the board.

Why don't we deal with the issues separately?

What are you trying to accomplish with speakers all around the house. Or did you mean around the ROOM?

You can't slave other amps off of this unit and have volume or source control at the receiver. It lacks any Preamp Outputs.

Tell us what you want to do, how things are connected (in detail) right now and maybe we can help you out.

It might also be helpful to know WHY you need to have multiple amps.

You need to get the multi room speaker distribution box, it will allow you hook up many speakers without damaging your amplifier. You will overload the amplifier if too many speakers are attached to amplifier.

See MCMELECTRONICS.COM such as P/N 50-2202
or PART-EXPRESS.COM

What you will need is an autoformer based speaker selector with volume control for 4 speaker pairs. This will take the left and right speaker wire out from your amplifier and distribute it to 4 pairs of speakers. Each pair of speakers gets it own volume control so you can control each room sound independently. It will also do speaker impedance matching so that your amplifier is not being over driven by the 4 pairs of speakers. The manual for the product you purchase will aid you in the proper settings of the auto former control. You can find this product from companies like Russound or Niles.

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.

it is not availlable to do such convertion.

Most amps will only power two sets of speakers direcrly hooked to amp (A&B). If you want audio throughout the house, I would recommend a PA system set up with individual room volume controls

your wall speakers may not be connected.... disconnect each speaker from the selector box and test with a small AAA battery to see if they are connected by putting the battery between each speaker's wires , you will hear it crackle ,then gradually connect each wall speaker onto the speaker connector box . If the first set does not work i suggest there may be a problem with your speaker selector box . Good luck
