Notes
● The sound output destination cannot be changed from
"Choose a device for sound output" on the "Control Panels".
When using the internal speaker of the Macintosh as the
sound output destination, disconnect the USB cable
connecting this unit and the Macintosh.
● When using headphones with this unit connected to the USB
port on the Macintosh, use the headphone jack on this unit,
not the jack on the Macintosh.
● Since the Macintosh issues a start-up sound at power-on
before the sound signal via the USB connection is activated,
the start-up sound cannot be issued via the USB connection.
To play the start-up sound via this unit, you need a separate
analog connection between this unit and the Macintosh.
(When USB MIX is set to "ON" from the Setup Panel of the
Application Software, you can mix the start-up sound via the
analog connection with the same sound via the USB
connection without making any change in the input selector
settings.)
