GAIN CONTROL

INPUT GAIN

The gain control knobs 1-4, located on the front panel, adjust the gain

for both microphone and auxiliary-level inputs of channels 1-4 (see Figure

1). For example, the channel 1 gain control is used for both the channel 1

microphone input (MIC LEVEL INPUT 1)

and

the channel 1 auxiliary level

input (AUX LEVEL INPUT 1). The auxiliary gain control knob (AUX IN) af-

fects only the auxiliary input (AUX IN).

OUTPUT GAIN

The master output gain control knob (MASTER) adjusts gain to both

the XLR balanced output (MIC/LINE LEVEL) and the auxiliary level output

(AUX LEVEL).

OUTPUT LEVEL METER

The six LEDs on the front panel labeled OUTPUT LEVEL METER illu-

minate to reflect the peak level of the mixed output signal from the

SCM268 (in reference to balanced line output) in dBu (0 dBu = 0.775 V).

Use the master gain control (MASTER) to adjust peak levels, as indi-

cated by the LEDs. The red LED illuminates when the output is 2 dB be-

low clipping.

PHANTOM POWER

When the phantom power switch on the back panel is on (12V PHAN-

TOM-ON), the SCM268 provides 12 V of phantom power to each XLR mi-

crophone input. The switch is recessed to prevent accidental

engagement. Most condenser microphones require phantom power. Use

it when connecting these types of microphones to the SCM268.

NOTE: Phantom power does not affect the operation of balanced

dynamic microphones. With phantom power on, they can be

connected to the SCM268 in combination with condenser

microphones that do use it.

OUTPUT LEVEL SWITCH

The output level switch on the back panel (MIC/LINE OUT) sets the

level of the balanced XLR output. When set to MIC, it reduces the output

by about 50 dB. Set the switch so that the output level matches the input

level of the device to which you are connecting the SCM268. The switch

is recessed to prevent accidental engagement.

NOTE: The output level switch does not affect the auxiliary output

(AUX OUT) level.
