Sync & Power Indicator
The LED on the front panel is normally red to indicate that power is present on the unit.
However, it also has a secondary role to indicate the status of the digital inputs: Fast flashing
between red and amber indicates a loss of digital input signal, or that the unit is being
calibrated.
Input Level Adjustment
Front panel potentiometers, coarse and fine, allow for adjustment of the gain of each
microphone input. The recessed screw-head potentiometer coarse control provides a total
gain range of 44dB, with the level knob fine control providing a ±12dB adjustment.
Connect the mic input and adjust the gain until the line output is at the level that you need.
The wide gain range allows the use of both dynamic and powered microphones.
Disabling the Fine Gain Control Knob
Each fine control also has the ability to be disabled via a jumper (JP1 for MIC1 and JP2 for
MIC2) situated on the PCB. When the jumper is fitted the control is enabled.
Fig 6-4: Jumpers to Disable Fine Gain Control.
Input Level Indicators
For each input there is a tri-colour LED to give an indication of the level of the incoming mic
signals. Green indicates -18dBFS, orange indicates -12dBFS and red indicates -6dBFS.
