Input Signal Connections
The OPPO HA-1 supports multiple analog and digital input connections. Depending on your intended usage, please
connect one or more input sources to the HA-1.
RCA Stereo Audio Inputs
You can connect an audio device with RCA analog outputs into the HA-1 using a pair of RCA cables. The analog signal
will be amplified and sent to the headphone and line level outputs. This input source is labeled RCA on both the
Source Selection screen and the remote control.
XLR Balanced Audio Inputs
You can connect an audio device with XLR balanced outputs into the HA-1 using XLR balanced cables. The analog
signal will be amplified and sent to the headphone and line level outputs. This input source is labeled XLR on both the
Source Selection screen and the remote control.
Coaxial Digital Audio Input
You can connect a device with a coaxial digital output into the Coaxial Digital Audio Input of the HA-1 using a coaxial
digital (75 ohm) cable. The digital signal will be converted by the internal DAC and sent to the headphone and line level
outputs. This input source is labeled COAXIAL on the Source Selection screen and COAX on the remote control.
