System Setup; Dip Switch Functions - Shure SCM800 User Manual

RACK MOUNTING THE SCM800/E
To mount an SCM800 or SCM800E in a standard 483 mm (19-inch) audio
equipment rack so that the front panel faces out, as shown in Figure 4.
Then secure the mixer to the rack with the four supplied Phillips head
screws.
SCM800/E CONNECTIONS
Refer to Figure 5 and proceed as follows:
1. Connect microphone- or line-level signal sources to the Channel
Input connectors (use conventional two-conductor shielded
cables).
2. Insert a screwdriver or similar tool into the slot above each block
connector and adjust the input slide switch as required: micro-
phone level (left position), 48 V phantom power (center position),
or line level (right switch position).
3. Connect the Line Level Output of the SCM800/E to the input
of other mixers, equalizers, amplifiers, or recorders. If multiple
SCM800/E mixers are to be used, refer to the Mixer Linking para-
graph of this manual.
4. If headphone monitors are to be used, plug them into the ¼-inch
PHONES jack on the front panel.
5. Connect the power cord to a 120 Vac (SCM800) or 230 Vac
(SCM800E) power source.
