Specifications
12k ohm electronically balanced, +20dBu (+20dBv) maximum input level via a 3 pin male XLR
cable plug. Common Mode rejection: > -50dB, 20Hz to 20kHz
Input section
Input section
Electronically balanced and floating, capable of driving +20dBu (+20dBv) into 600 ohms or greater via an XLR
female cable plug.
Frequency response: +/- 0.5dB, 20Hz to 20kHz (Low pass at 29kHz)
Noise: <-86dBu, all controls set flat, 22Hz - 22kHz
Distortion: Unity gain +10dBv output, no compression
THD: < 0.05% (20Hz-20kHz)
IMD: < 0.02% (SMPTE method)
Input section
Threshold Range: +20dBv to -30dBv continuously variable
Ratio: 1:1 to 20:1 continuously variable (Soft knee for low values with hard limit at
20:1)
Maximum Range: 30dB
Attack Time: Normal: Program dependent, with 200uS for fast transient overdrives.
Fast: Program dependent, with 20uS for fast transient overdrives.
Release Time: Normal: Typically 10 mSecs for 63% recovery from a 10dB 4mSecs
overdrive, and 1 Sec for 10dB 40 mSec
Fast:
Typically 2 mSecs for 63% recovery from a 10dB 4mSecs
overdrive, and 300 mSec for 10dB 40 mSec
Threshold Range: +20dBv to -30dBv continuously variable
Ratio: 20:1 at and above twice the set frequency
Freq Range: 1kHz to 10kHz continuously variable. 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 8dB above threshold. The frequency at which 3dB of gain
reduction occurs for 10dB of signal drive above threshold. 10dB of gain
reduction will occur at and above twice this frequency
Metering: 13 way dB calibrated LED meter display showing signal level below
threshold, threshold point and gain reduction
Stereo Link: Front panel switch selects Channels 1/2 and 3/4 to become stereo pairs.
Channel 1 and channel 3 assume master function for their pair. Side chain
control signal is mono summed
