A LED PHANTOM INDICATOR Illuminates when 48V phantom power switch is activated on
channel A.
B PHANTOM SWITCH PULL TO SWITCH. ON provides 48V phantom power to the input XLR
for use with phantom powered microphones (FET condensor).
C INPUT ATTENUATE Adjusts the amplitude of the incoming signal entering the preamplifier circuit.
This is the main control to set-up level to tape.
D DIRECT INPUT. Plug an instrument in here and use like a direct box with variable gain.
Use the center position of the PHASE SWITCH with this input.
E PHASE SWITCH. For channel A only. 0˚ is the normal setting where a positive goimg signal from
the mic pin 2 should produce a positive going signal to the speaker. The 180˚ position reverses the
phase (polarity) of the mic signal and is often needed with multiple mics and vocals.
F GAIN dB. For both channels. Not a pad - Adjusts the amount of negative feedback which will affect
gain, linearity, transient response, noise and clipping characteristics. Selects between 40, 42.5, 45, 47.5
and 50 dB of maximum gain.
G PHASE SWITCH. For channel B only. 0˚ is the normal setting where a positive goimg signal from
the mic pin 2 should produce a positive going signal to the speaker. The 180˚ position reverses the
phase (polarity) of the mic signal and is often needed with multiple mics and vocals.
H DIRECT INPUT. Plug an instrument in here and use like a direct box with variable gain.
Use the center position of the PHASE SWITCH with this input.
I INPUT ATTENUATE Adjusts the amplitude of the incoming signal entering the preamplifier circuit.
This is the main control to set-up level to tape for channel B.
J PHANTOM SWITCH PULL TO SWITCH. ON provides 48V phantom power to the input XLR
for use with phantom powered microphones (FET condensor).
K LED PHANTOM INDICATOR Illuminates when 48V phantom power switch is activated on
channel B
L LED POWER INDICATOR Illuminates when the preamplifier is powered.
M POWER SWITCH Switch up to turn on the power, down to turn the power off.
