(8) Monitor Output Level Meters

The 10-segment LED meters display the signal peak output levels of the rear panel Left

& Right Monitor outputs at the output of the D/A converters. These meters are before the

Monitor Level control (pre-fader) and reﬂect the D/A converter levels regardless of the

current Monitor Level and Headphone Level knob settings.

The dB values of the monitor meter LEDs are indicated between the left and right

channel meters. When digital clipping occurs, the red “C” (clip) LED illuminates.

If the monitor output level clips, reduce the monitor output level within the DAW and/or

reduce the output level of individual channels feeding the monitor output bus within the

Console application.

(9) Meter Switch

This switch determines whether the Channel Level Meters (#3) are displaying input

levels or output signal levels. Pressing the switch toggles the state of the meters and the

Meter Indicators (#6).

(10) Monitor ALT Switch

When ALT monitoring is conﬁgured in the Hardware panel within the Console Settings

window (when ALT COUNT is set to a non-zero value), this switch toggles between the

main monitor outputs and the ALT 1 outputs (line outputs 1 & 2).

When the ALT switch is engaged:

• The monitor signals are routed to outputs 1 & 2 instead of the main monitor outputs.

• The orange LED within the switch is illuminated.

• The Monitor Level Indicator (#13) is orange instead of green.

For complete details about how to conﬁgure and use the ALT monitoring features, refer to

the Apollo Software Manual.

Tip: ALT 2 outputs (line outputs 3 & 4) can be selected with the FCN switch

(#11) when conﬁgured in Console Settings, or in the MONITOR column within the

Console application.
