Input Headroom: >+20dBv.
Input CMMR: Better than -50dB 30Hz-20kHz. Typically -65dB at 1kHz.
Output level: >+20dBv into 600 ohms or greater.
Output Impedance: <1 ohm unbalanced.
Output Gain: ±20dB continuously variable.
Frequency Response: ±1dB 25Hz to 20kHz. Ultrasonic filter -3dB at 30kHz.
Noise: Equivalent input noise <-86dBv 22Hz to 22kHz
<-82dBv CCIR weighted.
Distortion: Unity Gain +10dBm output, below threshold.
THD. <0.03% 20Hz-20kHz. Typically 0.002% at 1kHz.
IMD. <0.01% SMPTE. Typically 0.003%.10dB compression.
Threshold 0dB. 1kHz, 5sec rel. Time (see note 1).
2nd Harmonic <0.15%.
3rd Harmonic <0.05%.
IMD (SMPTE) <0.25%.

General
Threshold Range: -30dBv to 20dBv continually variable.
Ratio: Infinite, at and above twice the set frequency.
Frequency Range: 700Hz to 20kHz continuously variable (see note 3).
Compressor
Threshold Range: -30dBv to 20dBv continuously variable.
Compressor Ratio: 1:1 to infinity:1 continuously variable. Over infinity available by
Barrier strip re-linking.
Maximum VCA Range: >30dB.
Attack Time: 50 microseconds to 80 milliseconds in 11 switched steps (see note
2).
Release Time: 5 milliseconds to 5 seconds in 10 switched steps and AUTO (see
note 2).
AUTO TIME Constant: A two part program dependant time constant. Attack time is
typically 200 microseconds on fast transient overdrives. Release is
typically 10 milliseconds for 63% recovery from a 10dB 4
millisecond overdrive, and 1 second for a 10dB 40 millisecond
overdrive.
