Apollo Solo USB Manual Unison 174
Deactivating Gain Stage Mode
Gain Stage Mode can be deactivated with any of these methods:
• Press and hold Apollo Solo USB’s top panel knob for at least two seconds
(Apollo Solo USB must be in Input mode by pressing the PREAMP button at least
once)
• Disable the Unison plug-in via the plug-in editor window within Console
• Disable the Unison plug-in via the on/off parameter within the plug-in interface
• Remove the Unison plug-in from Console’s Unison insert
• Change the selected channel by pressing the PREAMP switch on Apollo Solo
USB’s top panel
When Gain Stage Mode is deactivated, the following changes occur:
• The gain stage select function (pushing the top panel hardware knob) reverts to
the channel select function
• The channel selection indicator on Apollo Solo USB’s top panel stops flashing
• If a gain stage other than the first gain stage was being controlled, Apollo Solo
USB’s knob reverts to control of the first gain stage of the Unison plug-in, and the
level indicator color reverts to orange
Controlling Individual Gain Stages
Selecting Gain Parameters For Control
When the currently selected Unison plug-in channel is in Gain Stage Mode (when its
channel selection indicator is flashing), push Apollo Solo USB’s knob to cycle through
the available gain parameters within the Unison plug-in.
Note: Unlike Apollo Solo USB’s top panel knob, Console’s preamp gain control
only adjusts the first gain stage of any Unison plug-in when Apollo Solo USB is in
Gain Stage Mode. To adjust other gain stages from within Console, use Apollo Solo
USB’s gain knob or the Unison plug-in interface.
Gain Stage Colors
The gain stage being controlled is indicated by unique matching indicator colors on
Apollo Solo USB’s top panel and within the Unison plug-in’s interface.
The color of the level indicator on Apollo Solo USB’s top panel (the LED ring around the
knob) changes with each gain stage, and the matching color dot within the Unison plug-
in’s interface moves to the target gain parameter being controlled.
The gain stages available for control, and their associated colors, are:
• Orange – Gain stage one; the Gain parameter
• Amber – Gain stage two; the Level parameter
• Green – Gain stage three, the clean (non-modeled) output control
