To reset the compressor parameters
1 To reset the compressor parameters back to
default, press at bottom of section.
2 Click on YES at the Are you sure you want to Reset the
channel Protection? prompt.
To switch the compressor in/out of the circuit
To switch the compressor in or out of the circuit, press the In button to achieve required
condition, where
(button illuminated) shows compressor is in circuit and
(button extinguished) shows compressor is out of circuit.
To select hard/soft knee
To select soft knee or hard knee, press the Soft button to achieve required condition, where
(button illuminated) shows soft knee is selected and (button extinguished)
shows hard knee is selected.
4.4 Monitoring the Input Signals
To monitor the input signals there is a peak meter on each input channel control panel and a gain
reduction meter on the protection screen. An input response graph provides an overview of all four
input signals.
4.4.1 Meters - peak
Each of the four inputs has a 9-segment peak signal meter on its control panel for monitoring the
internal signal clipping and compressor headroom or gain reduction.
The top segment (illuminated in diagram left) monitors the internal signal clipping. It operates
independently of meter’s other segments, illuminating when signal clipping is detected at any
stage in the processing circuits, regardless of whether the input level is above or below the
compressor and/or limiter thresholds. Hence, the audio engineer has full visibility of internal
signal clipping that may result in audio distortion.
4.4.2 Meters – gain reduction
The Compressor panel of the Prot. (protection) screen shows the gain reduction using an eight-segment
meter.
