The jacks for channels 1 & 2 accept either a male XLR plug for connecting to the mic

The input that is used for the channel (mic or line) is specified with the Input Type but-

Connect the powered monitor speakers (or speaker amplifiers) here. Volume is set with
the Level knob (1) when Monitor is selected (6) with the Monitor button (10).

These ¼" phone outputs are accessed via software (Console or DAW). Line outputs 3 & 4
are used to send audio to other equipment.

The included power supply must be connected here (Apollo Twin cannot be bus pow-
ered). Rotate locking connector to prevent accidental disconnection.

After ensuring the locking barrel tabs are aligned with the chassis slots
and the barrel is fully inserted, rotate the barrel to secure the connector to the
chassis.
