(50Hz - 200Hz) SLOW Release <0.5% /FAST Release <0.8% / Below Limiting Threshold: <0.15%, 20Hz - 20kHz at +23dBm
(200Hz - 20kHz) SLOW Release <0.3% /FAST Release <0.4% / Level Limiter 0.5% max/Frequency Selective Limiter <0.5%
Below Limiting Threshold: <0.15%, 20Hz - 20kHz at +23dBm
Output Clipping Level: .+24dBm
Peak Limiter - ATTACK < 1us/dB-limiting
Peak Limiter - RELEASE - continuously variable between 30ms/dB-limiting (SLOW) and 6ms/dB-limiting (FAST)
Averaging Function -ATTACK and RELEASE approx.50ms / dB-limiting.
Frequency Selective Limiter -ATTACK: <1us / dB-limiting
Frequency Selective Limiter -RELEASE: 50ms (max) for any degree of reduction.
Operation: Circuit serves to hold gain at level of prior compression when input signal falls below Gating Threshold. If input signal remains below threshold in excess of 10 seconds, at the user’s option the circuit will (1) continue to HOLD GAIN at the level of prior compression; (2) slowly increase gain reduction to a maximum of 20dB (DELAY & FADE); or (3) slowly restore gain to the uncompressed value (DELAY & RELEASE).
Threshold Level: continuously variable; adjusts to open Gate on input signals of -40dBm at maximum sensitivity.
Threshold Weighting: -3dB points at 300Hz and 3kHz to restict gating operation to legitimate program material.
A series of straps on the circuit board permits setting the value of positive peaks to 100% (symmetrical), 105%, 110%, 115%, 120% or 125% of the negative peak value.
Two or more units may be interconnected for ganged gain reduction.
Sensitivity - Adjusts to accomodate input levels between -20 and +15dBm.
Impedance - 20k - bridging, with transformaer isolation.
Transformer-coupled Line Output feeds 600ohm line or bridging input at program levels between 0 and +15dBm.
