Glows when mains power is connected and unit is switched on via rear panel switch Activates a fast attack compressor circuit This is auto triggered on the output section and prevents clipping distortion at high output levels Activates a noise reduction circuit which cuts high frequency hiss etc when high gain and boost settings are used Activates the unigue DPC circuit with 14 Adjusts the amount of high freguency attack When pulled increase bass response These provide a post E Q signal for connection of external processors XLR socket provide a low impedance balanced line signal for mix desk either recording or sound re inforcement selects D I output either before pre or after post egualisers settings Neither affected by volume control Provides a line level signal for power amplifiers Headphones can be used for tuning or practice They should have a stereo jack plug fitted OVER 5 gt 20 LOAD INDICATOR 21 THERMAL INDICATOR Illuminates when internal protection circuit senses a fault at the output stage e g very low impedance speaker cable fault etc Output is automatically disconnected from speakers and has to be reset by turning off the amplifier for minimum 5 seconds Iluminates if the unit overheats due to restricted ventilation automatically resets on cooling The unit is fitted with a two speed cooling fan which automatically switches to high speed when required ON THE REAR PANEL
