Microphone powering
The selection of the microphone powering must be done before connecting it to avoid any damage caused by wrong
power supply.
OFF
The mike powering is switched off and the input shorted. When working with very low impedance
sources, it may not attenuate satisfactorily. Do not use this position in connection with
equipment, unprotected against short circuits.
DYN/LINE
The mike powering is switched off and the input can be used for dynamic microphones or for high
level input (max. input level 16dBu)
T 12 Tonader power to DIN (Pin1: Ground, Pin2: +12V, Pin 3: 0V)
+ 12 Phantom power (12 V on Pin 2 and 3)
+ 48 Phantom power (48 V on Pin 2 and 3)
Input amplification (GAIN) and high pass filter
GAIN
LF CUT
Gain selection between 0 and + 78 db with 12 step rotary commutator. This has the
advantage of exactly reproducing your setting at any time you need to.
Set your gain to have the OVD LED blinking at recording peaks. This gives you an
optimal S/N ratio without distortion.
With this toggle switch you can select between 80 Hz or 120 Hz to be filtered ( -3 dB).
Pan-Pot and Mono / Stereo - commuting
MONO
STEREO
PAN
In position MONO the signal of this channel is sent at equal level to the left and the
right master amplifier (independent of the pan pot position).
In position STEREO the pan pot distributes the signal contineously from left to right
depending on your setting.
Level control and overload indication (Frontpanel)
OVD
Rotary potentiometer controlling the level of the (already preamplified) input
signal before the master modul.
The OVD labeled LED lights up 6dB before limitating. That means distortion at
+32 dB with 0 dB amplification.
