3 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 fou\ r 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 ¼-inch sen\ d/receive insert jack. The SCM800 operates on 120 Vac power; the SCM800E operates on 230 Vac power. Both models are supplied with rack-mounting hardware, link cable and removable block terminal connectors. An accessory rack panel adapter (Model RKC800, available separately) converts the removable block input and output connectors to XLR connectors, and the Aux con - nectors to phono jacks. Compatible with Shure SCM810 and FP410 automatic micro - - phone 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 - Front-panel headphones output with level control - Peak-responding output limiter with selectable thresholds and - LED indicator SCM800 FRONT PANEL MODEL SCM800/E FRONT PANEL FIGURE 1 Microphone Channel Gain Controls 1 - 8: 1. Allows adjustment of microphone gain. Input LED 1 - 8: 2. Lights red at 6 dB below clipping level. Low-Cut Filter 1 - 8: 3. Recessed screwdriver adjustment provides adjustable low-frequency rolloff (high pass) to reduce undesirable low-frequency signals. High-Frequency Shelving Filter 1 - 8: 4. Recessed screwdriver adjustment provides level boost or cut in mid/high frequency region for compensation of off-axis lavalier microphones, or for cutting the high-frequency sibilance of vocal microphones. AUX Level Control: 5. Sets the input level for aux-level equipment connected to the adjacent ¼-inch phone jack INPUT or rear- panel ¼-inch AUX input. AUX INPUT ¼-inch Phone Jack: 6. Mixes external auxiliary- or line-level sources, i.e., tape recorders, into output. Signal appears at output of all linked mixers. MASTER Level Control: 7. Determines the overall mix level. Output Level Meter: 8. Nine-segment LED meter indicates peak output signal level. Last LED indicates limiter action. PHONES Control and ¼-inch Phone Jack: 9. Permits monitoring of mixer output through headphones. PHONES control deter - mines headphones output level. POWER LED: 10. Lights green when unit is powered. FEATURES
