Shure SCM800E manual Description, Features, SCM800 Front Panel

DESCRIPTION

The Shure Model SCM800 is a full-featured, eight-channel mi- crophone mixer for sound reinforcement, general audio re- cording, and audio-visual systems. Any low-impedance, bal- anced dynamic or condenser microphone, including a wire- less 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.

The SCM800 operates on 120 Vac power; the SCM800E oper- ates 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 connectors to phono jacks.

1.Microphone Channel Gain Controls 1 - 8: Allows ad- justment of microphone gain.

2.Input LED 1 - 8: Lights red at 6 dB below clipping level.

3.Low-Cut Filter 1 - 8: Recessed screwdriver adjustment provides adjustable low-frequency rolloff (high pass) to reduce undesirable low-frequency signals.

4.High-Frequency Shelving Filter 1 - 8: Recessed screw- driver adjustment provides level boost or cut in mid/high- frequency region for compensation of off-axis lavalier mi- crophones, or for cutting the high-frequency sibilance of vocal microphones.

5.AUX Level Control: Sets the input level for aux-level equipment connected to the adjacent 1/4-inch phone jack INPUT or rear-panel 1/4-inch AUX input.

6.AUX INPUT 1/4-inch Phone Jack: Mixes external auxil- iary- or line-level sources, i.e., tape recorders, into output. Signal appears at output of all linked mixers.

7.MASTER Level Control: Determines the overall mix level.

8.Output Level Meter: Nine-segment LED meter indicates peak output signal level. Last LED indicates limiter action.

9.PHONES Control and 1/4-inch Phone Jack: Permits monitoring of mixer output through headphones. PHONES control determines headphones output level.

10.POWER LED: Lights green when unit is powered.
