TRANSFORMER ISOLATED S/PDIF
Coaxial S/PDIF input is fully isolated using a Pulse transformer, to minimize the possibility of ground loop noise.
All JDS Labs DACs are built on 4-layer printed circuit boards to achieve proper USB characteristic impedance of 90 ohms.
USB AUDIO CLASS 2
EL DAC supports up to 32/384kHz audio using a dedicated 45/49MHz clock pair. While we claim no measurable superiority of high sampling rates, UAC2 and ASIO support satisfy your pursuit of bit-perfect listening.
100% SELF-POWERED USB
EL DAC is powered by a perfected supply network, with 12 linear regulators that ensure consistent rail voltage and super low ripple. Never be bothered by USB hubs or OS power difficulties again!
Enjoy the presence of your EL DAC with front and center mode selection via touch-sensitive light ring.
DIFFERENTIAL SUMMING OUTPUT
Differential output of the AK4490EQ DAC is summed by an OPA2227, with DC coupling throughout. Drive any load you wish, satisfactorily.
