Features

• Fully Calibrated - Detented controls guarantee repeatability and are quickly and easily set for any desired limiting function.

• Simple Operation - Even inexperienced personnel obtain effective results with "straight-up-and-down" control settings.

• Very Low Distortion - even at low frequencies, assured by open-loop gain control and unique ripple-cancelling circuits.

• Instant Display of limiting action by peak-responding indicators. Optional remote-mounting meter may be located at console.

Specifications

Frequency Response

±0.5 dB, 20Hz-20kHz

Signal-to-Noise Ratio

75dB, 20Hz - 20kHz referred to +4dBm line level

Distortion

• (50Hz - 200Hz) NORM Release <0.5% /FAST Release <0.8% /AVG Level Limiter<0.4%

• (200Hz - 20kHz)NORM Release <0.3% /FAST Release <0.4% /AVG Level Limiter <0.3%

• (Limiters OFF) 0.15% - 20Hz-20kHz at +23dBm

Peak Limiter Timing

• NORM Attack - <1us/dB-limiting

• DELAYED Attack - 2ms fixed delay +0.5ms/dB-limiting

• NORM Release - approx. 30ms/dB-limiting

• FAST Release - approx. 6ms/dB-limiting

• PEAK HOLD Attack - <10us/dB-limiting

• PEAK HOLD Release (drift) - <0.1dB/minute

Average Level Limiter Timing

• NORM ATTACK and RELEASE - approx. 50ms/dB-limiting

• SLOW A.G.C. - Operates in conjunction with NORM mode and requires approx. 10 seconds for complete gain reduction or restoration.

Stereo Coupling

Two or more units may be interconnected for ganged gain reduction.
