Manual/Auto: Automatic activation is defeated in the Manual position. In Manual mode, functions as a standard 8x1 mixer.
Last Mic Lock-On: Last Mic Lock-On feature keeps the most recently activated microphone turned on until a newly activated microphone takes its place. When
defeated, microphones turn off after their preset hold time.
Hold Time: Adjusts the time an activated microphone (which is not locked on) remains on after the talker stops talking. Settings are 0.4 seconds or 1.0 second.
Off-Attenuation: Changes the off-attenuation level from 15 dB to infinity (∞). With the 15 dB setting, an unused microphone is 15 dB lower in level than when
it is activated. With the ∞ setting, an unused microphone is completely off.
Limiter Threshold: Changes the output limiter threshold. Settings are OFF (factory setting), +16 dBm, +8 dBm, or +4 dBm (see Internal Modifications for other
threshold settings).
Link Global/Local: Determines whether each linked SCM810 output contains only its own program output, or that of all linked mixers (see Mixer Linking for
more information).

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 Channel 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: microphone (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-panel 1/4-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.
