• As soon as you connect the UA-1X to your computer, sound will no longer
be output from the speakers of your computer.
Connect external monitors or headphones to the UA-1X.
If you want sound to be output from your computer speakers, disconnect the
UA-1X from your computer.
Sound is distorted
• Could the Input select switch be set to LOW?
The sound may be distorted if the INPUT SELECT switch is set to LOW and you
input an audio signal higher than -10 dBu from the line input jacks. Set the INPUT
SELECT switch to HIGH.
• Could you have updated your software while the UA-1X was connected to
your computer?
Disconnect the UA-1X from your computer before you update your software.
The volume level of the instrument connected to LINE IN
is too low.
• Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
