*Mic Pre-Amp - ACTIVE volume control - adds about 60 dB of gain - brings mic up to line level
Mic/Line Select Swtich Chooses source
*Line Pre-Amp - ACTIVE volume control - adjusts line level
Phase Reversal Switch changes plarity by 180 degrees
Filter PASSIVE tone control
Equalizer ACTIVE tone control
*Input Fader - PASSIVE volume control - Controls the signal going into the Bussing Network

*Multi-track Recorder - Storage device for individual and combined audio signals - Can be tape or hard-disk based
