Polarity
Mic/Line, Send inputs to all outputs are non-inverting; Aux input to all
outputs is inverting
Overload and Shorting Protection
Shorting outputs, even for prolonged periods, causes no damage.
Microphone inputs are not damaged by signals up to 3 V; Line and
Monitor inputs by signals up to 20 V
Equalization
Low-frequency: 6 dB/octave cut, adjustable corner from 25 to 320 Hz
High-frequency: ±6 dB at 5 kHz, ±8 dB at 10 kHz, shelving
Limiter
Type: Peak
Threshold: Switchable: off, +4, +8, +16 (dBm at output)
Attack Time: 2 ms
Recovery Time: 300 ms
Indicator: Lights red when limiting occurs

Service Statement
For additional service or parts information, please contact the Shure
Service Department at 1-800-516-2525. Outside the United States, please
contact your authorized Shure Service Center.
*For systems requiring other mains connectors, use a power cord with
an IEC 320 type mating connector for connection to the SCM800, and
an appropriate plug on the other end for connection to the mains. The
supplied cord uses Harmonized IEC Cordage with color coding as fol-
lows: Brown = Line, Blue = Neutral, Green/Yellow = Ground.
