5043 Duo Compressor Limiter Specifications

Gain Range:

Continuously variable from –6 dB to +20 dB.

Threshold Range:

Continuously variable from –36 dB to +22 dB. 

Ratio Range:

 

 Continuously variable from 1.1:1 to “Limit” (40:1).

Attack Range: 

 Continuously variable from 20mS to 75mS

Release Range: 

 

Continuously variable from 100mS to 2.5 Seconds.

FF/FB:

Feed-Forward or Feed-Back VCA control. 

LINK:

  Multiple 5043’s may be daisy-chained via the rear panel jacks. When an individual channel is 

engaged, it’s control voltage appears at the rear panel LINK jack. When both channels are engaged 

they are linked together internally and their control voltage also appears at the rear panel LINK 

jack. 

LINE or BUSS input select:

Selects rear XLR input or ¼” Buss Input jacks to accept Portico series Buss Outputs. 

Maximum Output Level:

Balanced and Floating Transformer Output

+25 dBu.

Total Harmonic Distortion and Noise:

@ 2kHz, +20 dBu output level, no load.

Main Output, compressor bypassed:

Better than 0.001% 

Main Output, compressor engaged:  

Better than 0.06%

Noise: 

    

Mostly 2nd Harmonic

Measured at Main Output, un-weighted, 22Hz-22kHz,  terminated 40 Ohms.

With Gain at Unity, Compressor disengaged

Better than –103 dBu

With Gain at Unity, Compressor engaged:

Better than –92 dBu 

Frequency Response:

Main Output, Unity Gain

@ 18 Hz       –3 dB

@ 150 kHz   –3 dB 

Crosstalk

 

Measured Channel to Channel:

Better than –80 dB @ 16kHz

METERS A/B:

Monitors INPUT LEVEL and GAIN REDUCTION of either channel A or channel B.

5043 Power:

Voltage Range 

    9 to 18 Volts DC, 9Watts

Connector: 

    5.5mm X 2.5mm DC jack, Center Positive

Current consumption: 

    @ 9VDC = 1.0 A typical

    @12VDC = 730 mA typical

    @15VDC= 570 mA typical

    @18VDC= 480 mA typical
