How to connect your Apple II (or anything else) to BOSE Roommates
(or anything else) when you need manual volume control:

[aaaaaahhh... nothing like good ole'fashioned Text Graphics!]
[A] any piece of audio equipment with a sound output jack
[B] cord connecting outputs of [A] to inputs of [C]
[C] a stereo mixer or microphone amplifier
[D] cord connecting outputs of [C] to inputs of [E]
[E] the stereo system, 'box', or speakers you're hooking up to
The exact cables required for [B] and [D] depend on the type(s)
of inputs [A], mixer [C], and output [E] being used.
Note that microphone inputs are MONO; it takes two of them to
handle one STEREO channel.
Radio Shack does sell a small variety of mixers and microphone
amplifiers. I believe one of them will handle two microphones
and comes with individual slider volume controls for each one.
This is what you need for [C] if you only want to hook one thing
up to one other thing with volume control in between.
The mixers and mike amps with more than one stereo channel are
considerably more useful (and more expensive), but allow you to
hook more than one thing up to the speakers/stereo system at a
time (stereo card + standard Apple speakers! Hear your stereo
games' sound _AND_ your system crash *BEEP* at the same time!)
I own the Realistic STEREO MIXER (Radio Shack Cat. No. 32-1100A)
and I recommend it highly. It has three stereo inputs, plus two
microphone inputs: 4 stereo channels in all. The stereo inputs
each have slider volumes (one control for both left & right),
and they use standard RCA phono plugs as input. The microphone
inputs have independent volume, and they are amplified quite a
bit (increase your total output volume quite a bit w/ these!!)
The output is also standard RCA phono plug, plus it has a jack
for headphones.
Whatever you get, make sure to look at all the jacks in the back
of the thing and buy whatever cables/adaptors you will need at
the same time (the salesman should be able to help you with this).
Send mail if you have any additional questions, or if you are
unsure about what you want/need for your system. I will be
more than happy to help with:
* I have _this_ and _this_ .... what mixer do I buy?
* I am thinking about buying the _foobar_ mixer. If I want
to connect _this_ and _that_ to _the-other_ with it, what
cables, adaptors, etc. will I need and how much will it
cost? (Be sure to describe all the input and output jacks
of all the equipment involved).
You'll get a complete list of what you should probably use
to hook everything up, a decent guess of how much it will
cost you, and some options you have.

...I don't work for Radio Shack. In fact, I hate most of
their stuff. But when it comes to cables, adaptors, and
even stereo mixers, you gotta go someplace.................
