LISTENING TIPS
OPERATING CARE
For maximum signal fidelity, set the
DAC to at least 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:
www.hearingloss.org
When using USB mode, set sampling
frequency to match the majority of
your music collection (i.e., use 44100
Hz for 44.1kHz). Alternatively, you may
use ASIO mode in Foobar.
EL DAC automatically selects
appropriate sampling rate in coaxial or
optical modes.
Use gentle force when touching the
mode button, and when inserting or
removing cables.
To ensure an optimal noise floor,
always position audio equipment as far
away as possible from wireless devices.
