Complete details about the Apollo Twin X hardware controls and all connector jacks on
the front and rear panels are provided in this chapter.

volumes (monitors and headphones), see
Start chapter.

Controls Overview

Some Apollo Twin X 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 X'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. 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
Software Manual
PREAMP Mode
When Apollo Twin X is in Preamp mode, the top panel controls are related to
input functions only. To adjust input functions, press the PREAMP button to
enter Preamp mode and activate the input channel controls.
Important:
Apollo Twin X must be in Preamp mode to modify preamp gain
levels and other input options.
Note: Output functions (monitor and headphone) cannot be performed in Preamp
mode. Press the MONITOR button to perform output functions.
Preamp Channels
Apollo Twin X has two independent analog input channels for A/D conversion. Each input
channel has a preamplifier. The input channel preamplifiers are independently controlled
when in Preamp mode.
Preamp Controls
Apollo Twin X has one set of preamp input channel controls. The input channel controls
adjust all preamp functions for the currently selected input channel only.
