5 TRIPLE DIG INPUT MODULE
MONO
Every channel has a mono switch with LED to send a mono input signal to both outputs of
the module.
(PHANTOM POWER, not on the front panel. But 48 volt switch able by a jumper setting (see also
chapter 12))
MIC-TRIM
The trim control adds an extra 13dB of mic gain to the mic pre-amp. An optimum gain
range can be accomplished in this way.
GAIN
The gain control adjusts the incoming signal level on the MIC and DIG-LINE inputs.
LINE A
The triple-dig module default is in 'LINE A' mode (AES3). If no AES3 signal is connected
or the AES3 signal can’t be read, the LED will be red-flashing. Operating the 'DIG-LINE
B' switch or the MIC switch changes its mode.
LINE B
When ‘LINE B’ is selected (S/P-dif) the green LED is illuminated. If no S/P-dif signal is
connected or the S/P-dif signal can’t be read, the LED will be red-flashing.
MIC
MIC input selector switch between MIC-input or Line-A/B input. When the LED is illuminated
the MIC-input is activated.
HIGH
Adjusts high frequencies with +/- 12 dB at 10 kHz shelve.
MID
Adjusts mid frequencies with +/- 12 dB at 1 kHz bell.
LOW
Adjusts the low frequencies with +/- 12 dB at 60 Hz bell.
SUB
The sub switch assigns the signal in stereo to the sub output.
PROG(RAM)
The program switch assigns the signal in stereo to the program output.
STEREO AUX
Transmits a stereo signal to the AUX master post fader. A jumper on the board determines
whether this is pre or post VCA.
The channel 'ON' switch also affects the aux send (only when set to post fader).
