Chapter 3: Controls & Connectors
Complete details about the Apollo Twin hardware controls and all connector jacks on the
front and rear panels are provided in this chapter.
Note: To set input gain levels (mic, line, and Hi-Z) and output volumes (monitors
and headphones), see Setting Hardware I/O Levels in the Quick Start chapter.
Controls Overview
Some Apollo Twin 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 setting, the control must be activated for the function.
Operating Modes
Apollo Twin’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 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 has two analog input channels and one set of input channel controls. The
channel controls adjust all channel functions for the currently selected channel. After
switching the selected channel, the other channel can be adjusted.
Channel Selection
The currently selected channel is shown by the CH1 and CH2 indicators
at the upper left of the main display panel, above the input meters. The
top panel controls only adjust the functions for the currently selected
channel.
When in Preamp mode, press the PREAMP button or the LEVEL knob to
change the selected channel. Press again to switch back to the other channel.
