ALT Monitoring Overview
Apollo features ALT (alternate) monitoring capabilities. ALT monitoring can be used to
control alternate pair(s) of monitor speakers, which is convenient for quickly comparing
how a mix sounds through a different set of speakers. Up to two pairs of ALT monitors
can be used (one pair with Apollo Twin).
ALT monitoring is enabled in the Hardware Settings Panel within the Console Settings
window by increasing the ALT Count setting to a non-zero value.
ALT Monitor Connections
Note: The ALT channel output assignments cannot be modified.
Apollo, Apollo 8, Apollo 8p Apollo 16 – The ALT 1 monitor signal is routed to line out-
puts 1-2, and the ALT 2 monitor signal is routed to line outputs 3-4.
Apollo Twin – The ALT monitor signal is routed to line outputs 3-4 with Apollo Twin.
ALT Monitor Trims
Each pair of ALT outputs has its own trim (gain) setting, which is used
to offset any volume level differences with the volume level of the
main monitor speakers.
As the monitor level is adjusted, these offsets are maintained so
speakers can be accurately compared at any volume. The ALT trims
are located in the Control Room Column.
ALT Monitor Select
The ALT monitors are selected in the OUTPUT section of the Monitor
Column. The number of ALT output switches that appears here de-
pends on the ALT Count setting.
ALT Monitor Volume & Mute
The monitor level knob adjusts the output volume and muting of both
the ALT monitors and the main monitors.
