SCM800/SCM800E MICROPHONE MIXER SPECIFICATION SHEET
SPECIFICATIONS
Measurement Conditions (unless otherwise specified):
Line voltage 120 Vac, 60 Hz (SCM800) or 230 Vac, 50 Hz
(SCM800E); full gain; 1 kHz.
Source impedances: Mic 150 , Line 150
Terminations: Line 10 k, Phones 300 tip-sleeve and
ring-sleeve), Direct Out 10 k
Equalization controls adjusted for flat response, Channel 1 gain
control full clockwise, other gain controls full counterclockwise
Frequency Response (Ref .1 kHz, channel controls centered)
50 Hz to 20 kHz 2 dB; -3 dB corner at 25 Hz
Voltage Gain (typical, controls full clockwise)
Inputs
Outputs
Total Harmonic Distortion
<0.1% at +18 dBV output level, 50 Hz to 20 kHz (through 20
Hz-20 kHz filter; Input 1 and Master at 5, all other controls full
counterclockwise)
Hum and Noise
Equivalent Input Noise: –125 dBV (150 source; through 400
Hz—20 kHz filter)
Equivalent Input Hum and Noise: (150 source; through 20
Hz—20 kHz filter)
–123 dBV
Output Hum and Noise (through 20 Hz—20 kHz filter; channel
controls full counterclockwise):
Master full counterclockwise: -90 dBV
Master full clockwise: -62 dBV
Common Mode Rejection
>70 dB at 1 kHz
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 dam-
age. 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
Input LEDs
Light at 6 dB below clipping
Phantom Power
46 Vdc open-circuit through 6.8 k
series resistance per DIN 45
