Using the HA-1 as a Pre-Amplifier or DAC
The OPPO HA-1 can be used as a pre-amplifier or a Digital-to-Analog Converter (DAC) by connecting its Pre-amplifier
Output (PRE OUT) to a power amplifier or a pair of active speakers. The HA-1 offers both RCA and XLR Balanced
jacks. The output level is controlled by the Volume Knob or remote. The output is not muted when a pair of
headphones is plugged in. It is muted when the remote MUTE button is pressed.
RCA Stereo Audio Outputs
You can connect the HA-1 to a power amplifier or a pair of active speakers with RCA analog inputs using RCA audio
interconnect cables.

Triggers
When used as pre-amplifier, the Trigger Output of the HA-1 can be connected to the trigger input of a stereo power
amplifier using a 3.5 mm mono-to-mono mini-jack cable. When the HA-1 is turned on, the Trigger Output will supply a
+12 V voltage signal so the connected power amplifier can be turned on automatically. The Trigger Output can supply
up to 100 mA current.
