5043 - Compressor-Limiter Duo

The Portico 5043 embodies two independent Compressor-Limiters (Channels A and B) housed within a half rack, 1U module. They can be used independently (on two distinct tracks), linked as a stereo pair, or connected in sequence to provide two separate control slopes. When used as a stereo pair, linking the DC control circuits via the front panel A/B button enables the level of each channel to be held in a constant relationship. Rear panel TRS connections are provided to link multiple 5043s. This linking may also be extended to some of Rupert’s former AMEK CIB and DMCL units.

The 5043 Duo Compressor/Limiter is a powerful approach to dynamics processing for the Portico Series, designed with both tracking and mixing applications in mind. 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. S/C or 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 Buss Input jacks to accept Portico series buss outputs. Maximum Output Level: Balanced and Floating Transformer Output +25 dBu. Total Harmonic Distortion and Noise: @ 1kHz, +20 dBu output level, no load. Main Output, compressor bypassed Better than 0.0006%. Main Output, compressor engaged Better than 0.02% Noise: 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 input impedance output impedasnce
