12kohm electronically balanced,
+20dBu (+20dBv) maximum input level via a 3 pin male XLR cable plug.
Common Mode rejection
> -50dB, 20Hz to 20kHz.
Electronically balanced and floating, capable of driving +20dBu (+20dBv)
into 600ohms or greater via an XLR female cable plug.
Frequency response +/- 0.5dB, 20Hz to 20kHz
with all sections bypassed.
Noise < -86dBu, all controls set flat (CCIR 468-2)
Distortion THD < 0.05% 20Hz-20kHz at +15dBu, all
controls set flat.
Frequency Band 1 LF Sweepable from 40Hz to 320Hz.
Band 2 LM Sweepable from 150Hz to 1600Hz.
Band 3 HM Sweepable from 800Hz to 9kHz.
Band 4 HF Sweepable from 1.6kHz to 18kHz.
Width Variable from narrow (0.5Oct) to wide (3Oct)
Width control is inoperative in SHELF mode.
Filter Shelf Selects shelving EQ response (Bands 1 & 4)
Filter Defeat Selects broadband operation (Bands 2 & 3).
A bell-shaped EQ response is the norm for all
bands if these switches are ‘out’.
Threshold Variable from +20dBu to -30dBu.
Comp/Exp Variable from -30dB compression to +16dB
expansion. Soft knee at low settings.
Below Switched in for below threshold processing.
Fast Release Switched out to prevent pumping on
composite music mixes.
Switched in to respond to highly dynamic
signals.
Metering - per channel:
8 horizontal green LEDs indicate
compression activity.
8 horizontal red LEDs indicate expansion
activity.
Note: The 1-8 scaling is for convenience
only. It is not a decibel scale.
6 vertical LEDs display signal level (in dB)
relative to the threshold control’s setting.
Band In Switches each band into circuit.
EQ In Enables or bypasses the whole system.
Output Headroom indicating 4 LED display,
indicates CLIP (overload =+20dBu), +15dBu,
+10dBu, as well as signal present (-20dBu).
