(16) Mic/Line Inputs 1 & 2

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

input, or a ¼” phone plug for connecting to the line input.

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

button (13-a).

Caution: To avoid potential equipment damage, disable +48V phantom power on

the channel before connecting or disconnecting its XLR input.

(17) Monitor Outputs

Connect the powered monitor speakers (or speaker ampliﬁers) here. Volume is set with

the Level knob (1) when Monitor is selected (8) with the Monitor button (11).

(18) Line Outputs 3 & 4

These ¼” phone outputs are accessed via software (Console or DAW). Line outputs 3 & 4

are used to send audio to other equipment.

(19) Power Supply Input

The included power supply must be connected here (Apollo Twin MkII cannot be bus

powered). Rotate locking connector to prevent accidental disconnection.

Important: 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
