The sliders of the 1231 are 45mm center detent, with two selectable boost/cut ranges for precise gain adjustments. The unit features high pass filters with bypass, active balanced input and output connections, chassis/signal ground lift capabilities for quick hum isolation and an internal power supply. Multiple input and output configurations are provided for ease of use. The XLR and 1/4" TRS connectors use active balanced, low noise circuitry, with the addition of barrier strips. The 1231 was precision engineered to provide years of maintenance-free operation in any application. The magnetically isolated transformer, RF-filtered inputs and outputs, and power-off hard-wire relay bypass with two second power up delay, ensures compatibility with all types of installations.
