Chapter 4 Front Panel Overview
Input
M
IC
G
AIN
Sets the gain of the mic preamp for best compromise between signal-to-noise ratio
and headroom.
M
IX
Selects between the Mic input and Line input, or allows a mix of both inputs.
C
LIP
LED Monitors mic inputs for clipping. Illuminates 3 dB below the actual clip point.
M
UTE
LED Lights when the output of the 527E has been muted by a remote switch connected to
the 527E’s rear panel M
UTE
C
ONTROL
Euroblock connector.
Downward Expander / Compressor
E
XPANDER
T
HRESHOLD
Sets the threshold level for the downward expander. Signals below this
threshold are downward expanded (reduced in level).
C
OMPRESSOR
T
HRESHOLD
Sets the threshold level for the compressor. Signals above this
threshold cause gain reduction in the compressor.
C
OMPRESSOR
R
ATIO
Sets the compression ratio of the compressor. This determines the
amount by which above-threshold signals will be compressed.
D
OWNWARD
Indicates the amount of downward expander activity (gain reduction) at
E
XPANDER
any instant in time.
LED Display
C
OMPRESSOR
Indicates the amount of compressor activity (gain reduction) at any
LED Display instant in time.
Output Section
G
AIN
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.
O
UTPUT
LED Indicates the peak output level of the527E relative to the balanced output. 0 VU
Display 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
