LISTENING TIPS
OPERATING CARE
Listen safely to conserve your hearing:
www.hearingloss.org
Use gentle force when inserting or
removing cables.
To ensure an optimal noise floor,
always position audio equipment as far
away as possible from wireless devices.
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.
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 appro-
priate sampling rate in optical mode.
