Controls Overview

Some Apollo Twin MkII controls have multiple functions. The function of each control

depends on the current operating mode and the current settings within that mode. To

control a particular function, the control must be activated.

Operating Modes

Apollo Twin MkII’s top panel has two operating modes: Preamp and Monitor. The

function and availability of the top panel controls vary depending on the active operating

mode. The active mode is selected with the PREAMP and MONITOR buttons. Press the

button to activate the mode. Each mode is explained in greater detail below.

Note: All top panel functions can be operated concurrently (without switching

modes) from within the companion Console software application. See the Apollo

Software Manual for details.

PREAMP Mode

When Apollo Twin MkII is in Preamp mode, all top panel controls are related

to the input functions only. To adjust any input function, press the PREAMP

button to enter preamp mode and activate the input channel controls.

Note: Monitor and headphone functions cannot be performed in preamp

mode.

Preamp Channels

Apollo Twin MkII has two independent analog input channels. Each input channel has a

preampliﬁer. Both input channels can be independently controlled and used at the same

time for A/D conversion.

Preamp Controls

Apollo Twin MkII has one set of input channel preamp controls. The input channel

controls adjust all preamp functions for the currently selected input channel.
