RDL ST-GCA3 Gain Control Amplifier - Line Level

Input:+4 dBu balanced (nominal); -45 dBu to +20 dBu for rated outputMaximum Input Level:+26 dBuOutputs (2):+4 dBu 150 ? balanced LINE (nominal +0/-3 dB); -45 dBu balanced MIC into 150 ?AGC Range: 40 dB (output level maintained within 3 dB)Frequency Response:10 Hz to 20 kHz (+/- 0.75 dB)Noise:No input signal output un-muted:< -70 dBNo input signal output muted:< -80 dBInput signal present output muted:< -50 dBTHD+N:< 0.3% (50 Hz to 20 kHz; Typ. 0.05% @ 1 kHz)Mute Threshold:-46 dB below max input; -28 dB below normal inputMuting Response:15 sec. for 50 dBSLOW AGC response:8 sec. for 20 dB average level adjustmentFAST AGC response:3 sec. for 20 dB average level adjustmentOn Delay:50 ms to ramp from muted to fully on conditionIndicators (2):LED green variable intensity shows audio expansion LED yellow variable intensity shows audio gain reductionNote: Both LEDs display equal intensity for normal input level (equal available expansion and gain reduction).Power Requirement:GROUND-REFERENCED or FLOATING 2
