Tone Controls -
Each input card has a switch selectable high-pass
filter, and Bass and Treble controls. The inputs are
shipped with teh high-pass filter switched out, and
the tone controls set for "Flat".

Output Cards -
The output card has only slide switch, designed to set
the output to Master or Slave operation. If only one
chassis is to be used, no adjustment of the factory
setting, Master, is necessary.
If more than one chassis is to be used, consult page
11.

Inputs - Microphone
Each microphone input card has gain preset at the
factory. If condenser microphones are to be used, set
the gain slide switch to the low position on the
corresponding input card. The microphone input
cards are jumpered for 15 volt phantom power. (See
page 6 for details.)

Inputs - Line
Each line input card has gain preset at the factory for
unity. The line input cards are designed to be used
with devices such as telco echo-cancellers, compact
discs, and tape players. The mode switch on each line
input is factory preset to "Auto". Depending on the
installation, it may be desirable to set it to "Manual".
In manual mode, the automix gain function will not
effect the line input gain.
