Description

 

Input Impedance: 10k ohm balanced or unbalanced.

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%.

Cross Talk: Better than -85dB 20Hz to 20kHz, any settings.

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.

De-esser

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.

Stereo Switch (Rear Panel): Couples channel 1 and channel 2 control signals for stereo

operation. Indicated on the front panel by an LED.

Rear Connections: INPUT: XLR 3-31 or equivalent (Balanced)

OUTPUT: XLR 3-32 or equivalent (Unbalanced)

ACCESS POINTS: Barrier strip, providing control and subtract side

chain insertion points including HP and LP filter sends, pre-emphasis

and de-emphasis network sends; inverse phase sends for expander

mode; and control side chain DC access point for stereo, quad etc.,

coupling and gating.

Power: Switch selectable 120V or 240V, 50/60Hz, 15VA. AC fuses on the

rear of the unit. DC fuses located inside the unit.
