Manual Mode:
attenuation.
Auto Mode:
not add gain to the overall system level. Instead, when the level is adjusted above "0", the other
channels are attenuated to make the channel being adjusted sound louder in the mix without adding
to the system gain.

2. MASTER LEVEL

The master level controls the overall output level. The range is set for 10 dB of gain above, and 40
dB of attenuation.

3. DIP SWITCHES

Each channel has four DIP switches that control the following functions.
1
In the manual mode the channel level controls provide 6 dB of gain and 50 dB of
In the auto mode the control still provides 50 dB of attenuation, but the control does
A. MAN/AUTO
This switch determines whether the channel is operating in the automatic or manual mode.
B. OFF/MBUS
This switch is used to connect the channel to the system mutebus. This allows multiple
inputs to be muted simultaneously under external control. See MUTEBUS, page 7.
C. LO CUT/FLAT
This switch selects the low cut filter. The low cut filter provides a low frequency rolloff that
will help minimize unwanted noise (handling of mics, bumping of table, etc...). The rolloff
starts at 100 Hz (-3 dB) and is a 6 dB per octave filter.
D. OFF/+48
When this switch is in the +48 position, +48 volts of phantom power is supplied to the mic
± terminals. This provides power for condenser mics and should be defeated when using
dynamic microphones or unbalanced inputs.
