Note:
 The Coaxial, Optical and AES/EBU Digital Audio Inputs accept stereo PCM signals only. Compressed audio
signals such as Dolby Digital or DTS are not supported.
USB (Type B) Audio Input
You can connect your computer directly to the HA-1 using a USB-A to USB-B cable. This will allow your computer to
function as the digital source, and you will be able to use whatever playback software you prefer to output audio
through the HA-1. The digital signal will be converted by the internal DAC and sent to the headphone and line level
outputs. This input source is labeled USB DAC on the Source Selection screen and USB on the remote control.
Note:
 Depending on the operating system and playback software used, driver software, specific software settings and
configurations may be required in order to enable the computer to play audio into the HA-1. Please visit the HA-1
Support page on the OPPO web site (www.oppodigital.com) for driver download and additional help guides.
Mobile USB Audio Input
You can connect a compatible iPod, iPhone, or iPad into the Mobile USB Audio Input port on the front panel of the
HA-1. A 30-pin dock connector to USB cable or a Lightning™ to USB cable that comes with your Apple product is
required for this connection. The digital audio signal from your Apple product will be converted by the internal DAC and
sent to the headphone and line level outputs. This input source is labeled MOBILE on both the Source Selection
screen and the remote control.
Note:
 USB works with iPhone 5S, iPhone 5C, iPhone 5, iPhone 4S, iPad (4th generation), iPad mini, iPod touch (5th
generation).
