Oppo HA-2 - Manual (Page 4)

2. Introduction
Thank you for choosing the OPPO HA-2 portable headphone
amplifier and USB DAC. The HA-2draws upon the success of the
HA-1 desktop headphone amplifier, and is optimized for portable
use. Featuring a hybrid class AB amplifier and a USB DAC
supporting 384 kHz PCM and DSD256, the HA-2 offers high
performance digital-to-analog conversion for both Apple’s
iPhone/iPod and many Android devices. A 3.5 mm input works

VOOC rapid charging and a mobile device power bank make the
HA-2 a true companion for music on the go.
