The design of the STX 600 uses the same input section as the C610 and V610 Complimiters. The input section, (top knob), allows for quick setup for use as a limiter, limiter/compressor, or mild to moderate compression, (10:1). The output section, (bottom knob), allows for gain control for both compression compensation, and or microphone level adjustment. Switchable phase and phantom power are easily accessed via top mounted switches. The input pad allows for three settings, (0dB, -10dB, -20dB).
To allow for fast and accurate setup, the STX 600 utilizes two completely different indicator circuits. The input section utilizes an ultra-fast threshold circuit that indicates sub-microsecond peaks, yet allows visual representation of the onset of compression, via consistent lamp illumination. The output section indicator provides visual representation of actual output signal clipping, (+18dBu).
