The Shure Model SCM800 is a full-featured eight-channel microphone mixer for sound reinforcement general audio recording and audio-visual systems. Any low-impedance balanced dynamic or condenser microphone including a wireless microphone system can be used with the SCM800 mixer.
Each SCM800 accepts up to eight microphone- or line–level inputs and one aux-level input (two input jacks feed the same channel). Up to four SCM800 mixers can be linked to provide up to 32 input channels. Each input channel has a two-band equalizer switchable microphone- or line-level operation switchable 48 V phantom power and a 1/4-inch send/receive insert jack.
Features:
•Compatible with Shure SCM410 SCM810 and FP410 automatic microphone mixers
•Adjustable EQ per channel: low-frequency rolloff and high-frequency shelving
•48 V phantom power selectable for each input
•Active balanced microphone- and line-level inputs and line level output
•Highly RF-resistant chassis and circuitry
•LED indication of channel clipping
•Linking capability for systems up to 32 microphones
•Two Aux-level input jacks that feed one channel
•Insert jack on each channel
•Manual mixing of input channels
•Internal Modification permits 230 V operation (SCM800) or 120 V operation (SCM800E)
•Front-panel Live Sound > DJ Equipment > Headphones output with level control
•Peak-responding output limiter with selectable thresholds and LED indicator
SPECIFICATIONS
SCM800 8-Channel Microphone Mixer
- Frequency Response (Ref .1 kHz, channel controls centered): 50 Hz to 20 kHz +/- 2 dB; -3 dB corner at 25 Hz
- 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 ohm source; through 400 Hz_20 kHz filter); Equivalent Input Hum and Noise: -123 dBV (150 ohm source; through 20 Hz - 20 kHz filter); Output Hum and Noise (through 20 Hz to 20 kHz filter; channel controls full counterclockwise): Master full counterclockwise: -90 dBV; Master full clockwise: -62 dBV 8
- 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 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 (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 kilohm series resistance per DIN 45 596
- Operating Voltage: 120 Vac rated nominal (see Voltage Selection for 230 Vac operation in User Guide), 50/60 Hz, 200 mA
- Temperature Range: Operating: 0 degrees to 60 degrees C (32 degrees to 140 degrees F ); Storage: -30 degrees to 70 degrees C (-22 degrees to 158 degrees F)
- Overall Dimensions(H x W x D): 1-3/4 x 19 x 12-1/2 in (44.5 x 483 x 317 mm)
- Net Weight: 9 lb. 9 oz. (4.3 kg)
