Apollo Solo USB Manual Hardware Controls & Connectors 25
MONITOR Mode
When Apollo Solo USB is in monitor mode, all top panel controls are related
to output functions only. To adjust any output function, press the MONITOR
button to enter monitor mode and activate the monitor controls.
Important: Apollo Solo USB must be in MONITOR mode to adjust the
volume of the monitor and headphone outputs with the hardware controls. Monitor
volume can be adjusted with the Console software application when Apollo Solo
USB is not in monitor mode.
Stereo Outputs
Apollo Solo USB has two stereo outputs that can be controlled with the top panel
hardware: MONITOR and HEADPHONE. These two stereo outputs are independently
controlled.
Output Volume
The LEVEL knob is used to set the volume level for each stereo output independently.
The LEVEL knob adjusts the volume of the currently selected output only.
Output Selection
The currently selected output is shown by the MONITOR and
HEADPHONE indicators at the right of the main display, above and
below the output meters.
When in monitor mode, press the MONITOR button to change the
selected output. Press MONITOR again to switch back to the other
output.
Monitor Mute
When MONITOR is selected, press the LEVEL knob to mute (silence)
the stereo monitor outputs. Press the LEVEL knob again to unmute the
monitor outputs. The green level indicators (the ring of LEDs around the
LEVEL knob) and the monitor output selection indicator are RED when
the monitor outputs are muted.
