FIGURE 1

￿Microphone Channel Gain Controls 1–8: Allows adjustment of microphone gain.

￿Input LED 1–8:Lights green when channel is active; lights red at 6 dB below clipping level.

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

￿High-Frequency Shelving Filter 1–8: Provides level boost or cut in mid/high-frequency region to compensate for off-axis tone coloration, or for cutting high-frequency sibilance.

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

￿Aux INPUT 1/4-inch Phone Jack: Mixes external auxiliary- or line-level sources into output. This out is not automatic. Signal appears at output of all linked mixers.

￿MASTER Level Control: Determines the overall mix level.

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

￿PHONES Control and 1/4-inch Phone Jack: Permits monitoring of mixer output through headphones. The PHONES knob controls head- phones output level.

￿POWER LED: Lights green when unit is powered.

￿AC Power Connector and Rocker Switch: Connector supplies AC

power to unit when plugged into a power source: the rocker switch turns the unit on.

￿Microphone Logic: DB-25 male connector interfaces with each channel's GATE OUT, MUTE IN, and OVERRIDE IN logic terminals. See the Suggested Logic Applications section. NOTE: THIS IS NOT AN RS-232 PORT.

￿DIP Switch: The 7-position DIP switch provides setup options for the mixer (see DIP Switches section).

￿LINK IN/OUT Jacks: Allow multiple mixers to be stacked for addi- tional inputs. Up to 50 SCM810 mixers can be linked.

￿LINE OUTPUT Removable Block Connector: Active balanced line-level signal for connection to amplifiers, recorders or other mixers. Output can be modified to microphone level (see Internal Modifications).

￿DIRECT OUT 1/4-inch Phone Jacks: Provides non-gatedaux-level signal from each channel. Direct outs are wired pre-fader and pre-EQ. Can be modified for use as a gated channel output, send/receive insert point, or external speech gate for mixing consoles (see Internal Modifications section).

￿AUX/D.O./D.O. Switch: Located behind the Line Output connector, this switch selects either aux input function or direct output function for channel 8 Direct Out jack. Left switch position is AUX IN; center and right positions are DIRECT OUT.

￿INPUT 1–8 Removable Block Connectors: Active balanced micro- phone- or line-level inputs.

￿Input 1–8 MIC/PHM/LINE Switch: Located behind the removable block connector, this switch selects operation at either micro- phone-level (left), microphone-level with 48 V phantom power (cen- ter), or line-level (right) signals.
