Jitter-free audio performance.

An asynchronous USB 2.0 clock designed to ensure the accurate delivery of D/A conversions supplies a pure clock signal for reduced timing inaccuracies when converting digital signals into analog waveforms. This all adds up to maintains sound stage integrity and audio response, resulting in superior audio performance with minimal noise and distortion.

Built-in Power-house.

he AB-class analog amplifier, arranged in a twin mono format with separate left and right channels eliminates channel interference for clear, high-quality sound reproduction. Selecting ‘Tuned for SS-HA3’ with the EQUALIZER switch, the UDA-1 will deliver optimized audio ideally-suited for use with Sony SS-HA3 speakers (not supplied).
