RACK MOUNTING THE MIXER

To mount the SCM810 in a standard 483 mm (19-inch) audio
equipment rack, slide the mixer into the rack and secure it with
the supplied Phillips head screws, as shown in Figure 4. Use all
four screws.

SCM810/E CONNECTIONS

Make audio connections as follows (see Figure 5).
1. Connect microphone- or line-level signal sources to the Chan-
nel Input connectors (use conventional 2-conductor shielded
cables).
2. Insert a screwdriver or other tool in the slot above each block
connector and adjust the input slide switch as required: micro-
phone (left position), microphone with 48 V phantom power
(center position), or line level (right switch position).
3. Connect the SCM810 Line Level Output to the input of mixers,
EQs, amplifiers or recorders.
4. For headphones monitoring, connect headphones to the front-
1
panel / -inch PHONES jack.

5. Connect the power cord to 120 Vac (SCM810) or 230 Vac
(SCM810E). If the operating voltage is to be changed, refer to
the Internal Modifications section.

OUTPUT LIMITER SETTINGS

The output limiter prevents distortion during loud program peaks
without affecting normal program levels. This prevents overload-
ing of the devices connected to the SCM810/E output.

Increasing the individual channel or Master Gain controls will in-
crease the average output and, in turn, the amount of limiting. As
supplied, the output limiter is defeated. However, you can
change the limiter threshold so that the peak output level is +4,
+8, or +16 dBm. Refer to the Internal Modifications section.
