Description
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 headphones output with level control
- Peak-responding output limiter with selectable thresholds and LED indicator
| 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 ohms, Line 150 ohms |
| Terminations | Line 10 kilohms, Phones 300 ohms (tip-sleeve and ring-sleeve), Direct Out 10 kilohms. |
| Equalization controls | Adjusted for flat response, Channel 1 gain control full clockwise, other gain controls full counter-clockwise |
| 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 invertingOverload 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 |
| 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 | 44.5 mm H x 483 mm W x 317 mm D (13/4 x 19 x 121/2 in.) |
