    Description

    The ST-GCA3 constantly adjusts for changes in input levels, bringing up low levels, and reducing gain for high levels. The audio level is constantly adjusted to maintain the correct output. The AGC adjustment rate is switch-selectable. Making audio levels uniform and consistent improves the performance of nearly any type of audio system, and the ST-GCA3 SLOW mode is ideal for leveling music sources. The FAST setting of the ST-GCA3 makes it ideal for use in systems prone to loud bursts of audio, and inconsistent levels which must be constantly and quickly corrected. In paging systems, intercom systems, and mic mixing applications where intelligibility is a must the ST-GCA3 FAST mode can be the key to optimum performance.

      Features:
    • Automatic Gain Control
    • Wide Dynamic Range AGC
    • Slow Inaudible Gain-Reduction
    • Tight Dynamic Control
    • Positive, Fast Gain Reduction
    • Low-Noise and Low-Distortion AGC
    • RDL SupplyFlex Power Input Configuration
    Input:+4 dBu balanced (nominal)
    -45 dBu to +20 dBu for rated output
    Maximum Input Level:+26 dBu
    Outputs (2):+4 dBu, 150 balanced LINE (nminal, +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 dB
    No input signal, output muted:< -80 dB
    Input signal present, output muted:< -50 dB
    THD+N:< 0.3% (50 Hz to 20 kHz Typ. 0.05% @ 1 kHz)
    Mute Threshold:-46 dB below max input -28 dB below normal input
    Muting Response:15 sec. for 50 dB
    SLOW AGC response:8 sec. for 20 dB average level adjustment
    FAST AGC response:3 sec. for 20 dB average level adjustment
    On Delay:50 ms to ramp from muted to fully on condition
    Indicators (2):LED, green variable intensity shows audio expansion
    LED, yellow variable intensity shows audio gain reduction
    Note: Both LEDs display equal intensity for normal input level
    (equal available expansion and gain reduction).
    Power Requirement:GROUND-REFERENCED or FLOATING, 24 to 33 Vdc @ 40 mA
    Ambient Operating Environment:0 degrees C to 55 degrees C
