The notch filter frequency control is used to select the center frequency of the notch filter.
The bottom filter has a range of 40 Hz to 925 Hz. The middle filter has a range of 260 Hz to 6
kHz. The upper filter has a range of 500 Hz to 12 kHz.
Indicates that AC mains power is connected and power switch is in the "ON" position.

For use with low impedance microphones or low level sources. This is a transformer
balanced input with an impedance of 2,000Ω. Input sensitivity for nominal output is -56 dBu
to -19 dBu.

LINE INPUTS

These allow line level inputs to be used. This is a transformer balanced input through a 30
dB resistive pad. Input impedance is >20 kΩ.
This is a signal loop that allows an external device such as an EQ to be inserted into the
signal path of individual channels (refer to diagram below).
When no signal processor is being used or bypassing the signal processor is desired, this
switch should be in the "in" position. If a signal processor is being used, then this switch
should be in the "out" position.
