MIXER & SOURCE SELECTORS
Using the LF Filter
This switch provides control for a high pass filter on the mic input with low frequency roll
off at 125Hz. The roll-off filter is in circuit when the switch is down (towards the arrow).
Compression Active on Mic Input Only
With this feature enabled, the compressor/limiter will only operate when the microphone
input is selected. This mode becomes active when switch 3 is down (towards the arrow).
Peak Hold Disabled on LED Meter
By default, the LED meter operates with peak hold active on the top 5 segments. This can be
disabled by moving switch 4 to the up position (towards the arrow).
Stereo Line Input
The 2 x XLR 3 pin sockets used for the line input are electronically balanced. They have the
following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
Stereo Input Gain Pad
The line input channel with the volume control fully up, has a gain of +6dB. An extra 10dB of
gain is available by depressing the rear panel INPUT LEVEL switch. The LINE VOLUME control
is located on the front panel.
Stereo Line Output
The XLR 3 pin plug output connectors are electronically balanced and can be wired
unbalanced by grounding the non-phase signal, allowing you to feed balanced and
unbalanced equipment. They have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
The connector provides a line level output with an impedance of <50Ω and a maximum
output level of +28dBu.
Stereo Output Gain Pad
The output gain switch provides a 10dB drop in gain.
