Overload and Shorting
Shorted outputs, even for prolonged periods, cause no damage.
Microphone inputs of up to 3 Vrms cause nodamage. Line and
monitor can withstand signals of up to 30 Vrms.
Input Peak Indicators

Output Peak Indicator
Lights red at 6 dB below clipping level
Output Clipping Level
≥ +18 dBm at line output into 600 Ω
Low–Cut Filters
