23
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 d20dBu (+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).
