  • Page 3: Description, System Features, Operating Principles

    Any low-im- pedance dynamic or condenser microphone (including wireless) can be used with the SCM810/E. Multiple SCM810 mixers can be linked to other SCM810/E mixers, as well as to Shure Models FP410, SCM410, SCM800, and AMS8100 mixers.

    (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.

    OFF (factory setting), +16 dBm, +8 dBm, or +4 dBm (see Internal Modifica- tions for other threshold settings). Link Global/Local: Determines whether each linked SCM810 output con- tains only its own program output, or that of all linked mixers (see Mixer Linking for more information).

    48 V phantom power (center position), or line level (right switch position). 3. Connect the SCM810 Line Level Output to the input of mixers, EQs, amplifiers or recorders. 4. For headphones monitoring, connect headphones to the front-panel 1/4-inch PHONES jack.

  • Page 7: Equalizer Functions, Using An Equalizer/feedback Controller With An Automatic Mixer, Basic Mixer Operation

    USING AN EQUALIZER/FEEDBACK CONTROLLER WITH AN AUTOMATIC MIXER When setting up a sound system which has an outboard equalizer or feed- back controller in the signal chain, set the SCM810 to MANUAL. This acti- vates all microphone inputs, so every possible feedback path is open. With the SCM810 in MANUAL mode, equalize the sound system and/or “Ring...

  • Page 8: Networking Multiple Mixers, Global/local Functions, Link Cables

    NETWORKING MULTIPLE MIXERS If additional inputs are needed, more SCM810 mixers (as many as 50) can be “linked” using supplied link cables. Such a configuration can provide up to 400 microphone inputs. To link multiple mixers, connect the LINK OUT of the first mixer to the LINK IN of the next mixer, and so on (see Figure 8).

    SCM810. An existing sound system using 24-volt relays can be used with the SCM810 without modification if the relay coil current draw is under 500 mA. “Filibuster” Mode In normal operation, when several people talk, each microphone gates on LOGIC so that no speech is missed.

  • Page 13: Voltage Selection

    For information on logic gate use, refer to the TTL Cookbook and CMOS Cookbook, both by D. Lancaster, Howard Sams Publishing Co. VOLTAGE SELECTION The SCM810 can be internally modified to operate from 230 Vac, 50/60 Hz power. WARNING: Voltages in this equipment are hazardous to life.

  • Page 14: Internal Modifications

    WARNING: All modifications must be performed by qualified service tech- nicians. This section describes SCM810 modifications that can be made using sol- der “jumpers” on the printed circuit board; the pads where jumpers may be used are placed close together so that a single solder drop functions as a jumper.

    SCM810 Speech Gate for Mixing Console The SCM810 can be used in conjunction with large mixing consoles to pro- vide automatic mixing for talk shows, panel discussions, and news shows. Large consoles have channel insert jacks so that external signal process- ing devices can be patched into individual channel signal paths.
