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.”
