LISTENING TIPS
For maximum signal fidelity, set the
DAC to 24-bit audio and adjust digital
volume slightly below 100% at your
computer. Only control volume from
your amplifier.
Listen safely to conserve your hearing:

When using USB mode, set sampling
frequency to match the majority of
your music collection (i.e., use 44100
Hz for 44.1kHz).
OL DAC automatically selects appropriate sampling rate in optical mode.
To ensure an optimal noise floor,
always position audio equipment as far
away as possible from wireless devices.
OPERATING CARE
Use gentle force when inserting or
removing cables.
