Levels in the Getting Started chapter.
Controls Overview
Some Apollo Solo USB 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 Solo USB’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.
Tip: All top panel functions can be operated at the same time (without switching
modes) from within the companion Console software application.
PREAMP Mode
When Apollo Solo USB is in preamp mode, the top panel controls adjust the
input functions only. To adjust any input function, press the PREAMP button
to enter preamp mode and activate the input channel controls.
Important: Apollo Solo USB must be in PREAMP mode to adjust input
channel settings with the hardware controls. Input settings can be
adjusted with the Console software application when Apollo Solo USB is not in
preamp mode.
Preamp Channels
Apollo Solo USB 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 Solo USB has one set of input channel preamp controls. The input channel
controls adjust all preamp functions for the currently selected input channel. The other
input channel preamp can be adjusted by changing the selected channel.
