Input
MIC GAIN
Sets the gain of the mic preamp for best compromise between signal-to-noise ratio
and headroom.
MIX
Selects between the Mic input and Line input, or allows a mix of both inputs.
CLIP LED
Monitors mic inputs for clipping. Illuminates 3 dB below the actual clip point.
MUTE LED
Lights when the output of the 527E has been muted by a remote switch connected to
the 527E’s rear panel MUTE CONTROL Euroblock connector.
EXPANDER THRESHOLD
Sets the threshold level for the downward expander. Signals below this
threshold are downward expanded (reduced in level).
COMPRESSOR THRESHOLD
Sets the threshold level for the compressor. Signals above this
threshold cause gain reduction in the compressor.
COMPRESSOR RATIO
Sets the compression ratio of the compressor. This determines the
amount by which above-threshold signals will be compressed.
DOWNWARD
EXPANDER
LED Display
Indicates the amount of downward expander activity (gain reduction) at
any instant in time.
COMPRESSOR
LED Display
Indicates the amount of compressor activity (gain reduction) at any
instant in time.
527E
Downward Expander / Compressor
Output Section
GAIN
Sets the overall gain of the 527E’s output over a ±15 dB range. The actual adjustment
point is in the expander/compressor’s VCA, which is pre-EQ.
OUTPUT LED
Display
Indicates the peak output level of the527E relative to the balanced output. 0 VU
on the display corresponds to +4dBu at the balanced output. For unbalanced
applications, the actual output level is 6 dB lower than that shown by the display.
Note
The 527E’s mic output will have an output level of -36dBu when the display
indicates 0 VU.
Bypass
EXP/COMP
IN/BYPASS Switch
Defeats the downward expander/compressor. This is not a hard-wire
bypass.
EQ/FILTERS
IN/BYPASS Switch
Disengages the EQ and Filter section when set to the Bypass (Out)
position. This is a hardwire bypass.
