SCM410 CONNECTIONS
1.
Connect microphone signal sources to the Channel Input connec-
tors. Use conventional 2-conductor shielded audio cables.
2.
If any condenser microphones are connected, set the +12V phantom
power DIP switch to ON.
.
LINKING MULTIPLE MIXERS
If more than four inputs are needed, multiple Shure SCM410,
FP410, or SCM810 mixers can be linked by connecting the LINK OUT
of the first mixer to the LINK IN of the next mixer, and so on. See Figure
2. Leave the LINK IN jack of the first mixer and the LINK OUT jack of
the last mixer unconnected.
When properly linked, the mixers will operate as a system. Auto-
matic mixing functions will be shared by all units. All input signals ap-
pear at all linked mixer outputs. Each mixer's Master level control only
controls its own output. However, actual off-attenuation will increase as
more mixers are linked. This reduces excessive noise and reverbera-
tion contributed by the increased number of microphones.
IMPORTANT: When using logic terminals on linked mixers,
connect the LOGIC GROUND terminals of each unit together.
NOTE: SCM410 link connections are unbalanced. To minimize
hum and noise, avoid using longer link cables. Use high
quality, shielded cable, and keep them away from sources of
magnetic or electrical noise, such as power transformers or
3.
Connect the SCM410 Mic/Line Level Output to the input of mixers,
EQs, amplifiers or recorders.
4.
Connect the power cord to 100-120 Vac (SCM410) or 220-240 Vac
(SCM410E)

light dimmers. To minimize ground currents, make sure linked
mixers are connected to the same AC power mains.
