Mixers
Heart of a sound system.

Mixer is used to:
	* Control and adjust individual input devices (mics, playback devices, etc.)
	* Combine (mix) individual inputs together into a few channels
	* Distribute these channels to desired output devices (amps and speakers)

This is stage where nearly all active adjustments happen.

Input of modules will often linclude:
	* Line level input jack, for CD players, tape decks, 
        computer line outputs, etc.
	* Mic level jack, for low-impedance microphones.


Input module controls usually include:
	* Input selector: selects source preamp
	* Trim pot: sets max. gain for channel
	* Aux./Mon. send: diverts signal to extra outputs
	* Equalizer (EQ): frequency adjustments
	* Output select: selects next step in sounf path
	* Pan pots: for smooth transitions between outputs
	* Solo: turns off all other inputs being sent to headphones
	* Potentiometer (Pot): gain control

From the imput module, the sound signal will be sent to the 
output master or submasters selected for that module.

Submasters:
Output controlers, which can be used to group selected individual inputs 
and to pass the sum of those inputs on the the Master fader, or the 
combined signals can be sent directly to their own own submaster output jacks.

Master:
Final control of the combined (mixed) signals from the input modules 
and/or the Submasters, assuming they have been assigned to the Master 
via assign switches.
