Front Panel
POWER: Switches the unit on or off. The adjacent LED lights when the unit is ON
FRONT: Switches the audio input to the front mic/line combo connector.
NOTE: The DI input always overrides the Mic input, whether the FRONT
switch is pressed or not.
DIGI: Switches the line input and output to the rear digital module. In digital
mode the front/rear mic input, DI input, and analogue line output
continue to operate normally.
NOTE: The digital module is an optional extra and is not included as
standard.
XLR/Jack combo input:
Use the XLR input for microphone sources and the 6.35mm jack input for
line-level sources.
48V: Applies 48V phantom power to the XLR microphone input (front and
rear). The adjacent LED lights when phantom power is active.
Lo Z: The default input impedance on the microphone input is 1200Ω. Pressing
the Lo Z switch reconfigures the input for 300Ω input impedance.
LIFT: Provides ground lift for the DI input. If hum/buzz occurs when using a DI
input, pressing this switch may alleviate the problem by breaking any
ground loop.
-20: Provides 20dB of attenuation to the DI input. In the default position (no
attenuation) the input impedance of the DI input is approximately 1MΩ.
When set to -20dB attenuation (switch depressed) the input impedance
of the DI input is approximately 10kΩ.
DI I/P: High-impedance balanced input for direct injection.
NOTE: When a 6.3mm jack is inserted into the DI input, all other
microphone inputs are automatically disconnected. Use the Mic
side of the gain control when using the DI input.
