4 2
Peak Limiter
Threshold Range: +4dBv to +20dBv continuously variable.
Ratio: >20:1.
Attack Time: 150 microseconds, fast setting.
750 microseconds, slow setting.
Release Time: 100 milliseconds, fast setting.
500 milliseconds, slow setting.
Notes
Note 1: Harmonic distortion will increase with reduced frequency and
shorter time constants, which is inherent in this type of equipment.
Note 2: Attack times are those as measured to achieve 63% of final gain
reduction with a step signal of 8dB above threshold. Release times
are those as measured to achieve 63% recovery of open gain or
removal of a signal of 8dB above threshold.
Note 3: The frequency is that at which 3dB of gain reduction occurs for 10dB
of signal overdrive above threshold. 10dB of gain reduction will
occur at and above twice this frequency.
Facilities
Mode Switch: 3 position switch to select:
Bypass Switch: Normal mode to allow simultaneous wide band de-essing,
compressing and peak limiting.
MON S.C. Switch: Wide band de-ess mode utilising compressor side chain.
Meter Input Switch: HF de-ess mode utilising compressor side chain.
Bypasses all functions of the unit at unity gain, allowing all
parameters to be adjusted and levels checked whilst 'on air'.
Momentarily connects the control side chain to the output of the
unit to allow monitoring of control insert return.
Momentarily connects the input signal to the output level meter to
allow comparison of input and output levels prior to operating the
bypass switch.
Metering: BELOW THRESHOLD: 5 LEDs to indicate side chain level from
18dB to 0dB ref the set threshold.
GAIN REDUCTION: 9 LEDs to indicate the amount of gain
reduction from 3dV to 27dB. Display 'bright-up' at 30dB of
reduction.
OUTPUT: 12 LEDs to indicate output level from -24dBm to +18dBm.
Display 'bright-up' at +21dBm (clip).
DE-ESS: 2 LEDs to indicate normal and hard de-essing.
PEAK LIMITING: 2 LEDs to indicate normal and hard peak limiting.
