Linking Multiple SCM800 Mixers

Up to four SCM800 mixers can be “linked” using the supplied link cables If additional inputs are needed. Such a configura- tion can provide 32 mic inputs. Refer to Figure 6.

When multiple SCM800 mixers are linked, all input signals ap- pear at all linked mixer outputs––there is no master-slave rela- tionship. The output controls and functions of each linked mix- er are post-link and do not affect the signals appearing at other linked mixer outputs. Each mixer’s Master level control only controls its own output. Each output can be used independent- ly. In a linked system, the Aux input of any mixer appears at each linked mixer’s output. See Internal Modifications to de- feat the linking of Aux signals.

Link jacks should be connected sequentially: the LINK OUT of one mixer to the LINK IN of the next, leaving one LINK OUT and one LINK IN unconnected.

NOTE: Each doubling of the number of linked mixers de- creases the master output level by 6 dB.

LINKING TO OTHER SHURE AUTOMATIC MIXERS

An SCM800 can be interfaced with Shure SCM810 and FP410 automatic microphone mixers via the link jacks. Linking an SCM800 is equivalent to adding an additional mixer with eight open microphones to a system. Because of the loading effects of additional open microphones, only one SCM800 can be linked to an automatic system. When using more than one SCM800 with other Shure automatic mixers, connect them as described in the following section.

NOTE: When linking an SCM800 to an automatic system, use the SCM800 LINK OUT jack to interface with the LINK IN jack of the automatic system (see Figure 7).

USING AN SCM800 AS A SUBMIXER

The master output of the SCM800 (or the output of a mixer in a group of linked SCM800 mixers) can be connected to a chan- nel input or the aux input of an automatic mixer, or other types of mixers. See Figure 8.

ADDITIONAL LINK CABLES

Additional 381 mm (15 in.) link cables are available as Shure Part No. 95A8889. Longer cables in a variety of lengths are available from Apple Computer as computer printer connec- tions; they are variously referred to by Apple as “shielded serial cable with two mini DIN-8 connectors,” and “Apple System Pe- ripheral–8 Cable.”
