LINKING MULTIPLE SCM800 MIXERS
Up to four SCM800 mixers can be “linked” using the supplied link cables
If additional inputs are needed. Such a configuration can provide 32 mic
inputs. Refer to Figure 6.
When multiple SCM800 mixers are linked, all input signals appear at all
linked mixer outputs––there is no master-slave relationship. The output
controls and functions of each linked mixer 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 inde-
pendently. In a linked system, the Aux input of any mixer appears at each
linked mixer’s output. See InternalModications to defeat the linking of
Aux signals.
Link jacks should be connected sequentially: theLINK OUTof one mixer to
the LINK IN of the next, leaving one LINK OUT and one LINK IN uncon-
nected.
NOTE: Each doubling of the number of linked mixers decreases the
master output level by 6 dB.
LINKING MULTIPLE SCM800/E MIXERS
FIGURE 6
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).
LINKING AN SCM800/E TO OTHER AUTOMATIC MIXERS
FIGURE 7
The master output of the SCM800 (or the output of a mixer in a group of
linked SCM800 mixers) can be connected to a channel input or the aux
input of an automatic mixer, or other types of mixers. See Figure 8.

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 connections; they are variously referred to
by Apple as “shielded serial cable with two mini DIN-8 connectors,” and
“Apple System Peripheral–8 Cable.”
