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. -
Page 17: Bluetooth Audio Connection
After pairing successfully, the HA-1 will display that it is Connected. Once you have paired a Bluetooth device, the HA-1 will attempt to reconnect to it when the device is in range and the BLUETOOTH input has been selected on the HA-1. If a new device needs to be paired, but the HA-1 is already connected to a device, you will need to disconnect that device in order to pair the new device. -

Power On / Off When the HA-1 is initially connected to AC power, it stays in standby mode. Pressing the Power Button on the HA-1 will result in the Power Status Indicator turning blue, indicating the HA-1 has powered on. When the unit is powering on, the OPPO logo will appear on the screen. -
Page 19: Source Selection
It is possible that the Volume Knob may be inadvertently rotated when the HA-1 is off. In order to protect the output device, there is a protection mechanism built-in to the HA-1’s volume control. When the device is powered on, if the Volume Knob position is higher than the previously used volume level before the unit was powered off, the Volume Knob will automatically return to the previous volume level. -
Page 20: Mute
HEADPHONE AMPLIFIER HA-1 For those who use the HA-1 as both a headphone amplifier and a pre-amplifier, it is possible to assign the MUTE button to the Pre-amplifier Output only. This way the user can mute the large speakers with the MUTE button while still being able to listen to the headphones. -

Page 22: Screen Dimmer Setting
When using the HA-1 as both a headphone amplifier and a pre-amplifier, it may be desirable to mute the Pre-amplifier Output while listening to headphones. For example, if the HA-1 is connected to a pair of active speakers, it may be easier to mute the Pre-Amplifier Output than to turn off both speakers when you want to listen with headphones. -
Page 23: Headphone Gain Selection
The following selections are available: High (default) – The headphone amplification circuit of the HA-1 applies the high gain level, which is about 18dB higher than Normal. This setting is recommended for headphones with low sensitivity or high impedance. -
Page 24: Home Theater Bypass Mode
HA-1’s volume control is bypassed for the Pre-Amplifier Output. The Pre-Amplifier Output level will be exactly the same as the input signal level (unity gain). This feature helps when integrating the HA-1 as a high performance stereo pre-amplifier into a multi-channel home theater sound system. The following diagram... - Page 25 Although digital input sources can be configured to Home Theater Bypass mode, it is not recommended. This is because most digital source components do not offer volume control. However, if you intend to use the HA-1 as a pure DAC device connected to another pre-amplifier with proper volume control, you should configure the digital input source to Home Theater Bypass mode.
