Shure SCM810 8-Channel Automatic Microphone Mixer
Availability:
In StockAvailable for shipment within one business day, or pickup from our Jamaica, NY warehouse during regular business hours.
Description
This eight-channel automatic mixer features the Shure patented IntelliMix®, which activates only microphones being addressed, minimizing poor audio caused by multiple open microphones. The SCM810 is designed specifically for installed sound applications. Features include adjustable EQ per channel, 48 V phantom power, active balanced microphone - or line-level inputs, line-level outputs, highly RF resistant chassis and circuitry, complete logic control of microphone activation, linking capacity for up to 400 microphones, with an internal power supply. 120/230 Vac power.
Features:
- Eight balanced mic-line input channels (Phoenix block connectors)
- One unbalanced 1/4" aux level input
- Eight unbalanced 1/4" direct line level outputs
- One balanced master line level output (Phoenix block connector)
- Selectable 46V phantom power per channel
- Level selectable peak output limiter
- Full rack width (single rack height)
| Measurement Conditions (unless otherwise specified) | Line voltage 120 Vac, 60 Hz (SCM810) or 230 Vac, 50 Hz (SCM810E); full gain; 1 kHz, one channel activated; source impedances: Mic 150 ohms, Line 150 ohms terminations: Line 10 kilohms, Phones 300 ohms (tip-sleeve and ring-sleeve), Direct Out 10 kilohms; Auto mode, equalization controls adjusted for flat response |
| 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) | |
| 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 | -70 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 Input Channel Activation |
| Attack Time | 4 ms |
| Hold Time | 0.4 s (switchable to 1.0 s) |
| Decay Time | 0.5 s |
| Off-Attenuation | 15 dB (switchable to infinity) |
| 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 |
| Input LEDs | Green on channel activation, red at 6 dB below clipping |
| Phantom Power | 46 Vdc open-circuit through 6.8 k 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 (-20 degrees to 165 degrees F) |
| Overall Dimensions | 44.5 mm H x 483 mm W x 317 mm D (13/4 x 19 x 121/2 inches) |
| Net Weight | 4.3 kg (9 lb 9 oz) |
