Connecting the DAC
You need a compatible power supply to use this DAC. A wide range of power supplies is accepted.
1. Connect the DAC to your computers USB port
2. Connect the power supply to the DAC first
3. Connect the power supply to the mains voltage
Note: If the computer goes to sleep while the DAC is connected, then you might have to unplug and replug the DAC, as the power management feature on some computers doesn’t quite understand the USB isolator.
How to select the Hifime DAC as the output device
See the guide for selecting the device as the output.
Windows ASIO driver (optional)
See this guide for installing Windows drivers.
Note: You can only output sound from one program at a time when using ASIO.
There is an analoge volume control that control the headphone output on the front of the DAC.
Additional feature: Digital Coaxial output
This DAC does also output a digital coaxial signal through the an additional RCA connector on the backside of the DAC.The SPDIF signal comes directly fromt the USB receiver chip, the DAC chip is not used when outputting a digital SPDIF signal.
General considerations and warnings
There is a couple of things you should be aware of when using the DAC.
1. Always disconnect headphones or turn off your amplifier before plugging/unplugging the DAC. This is because there might be a loud pop when connecting/disconnecting the DAC.
2. Check volume level before start playing when using headphones, as the level might be too loud. The computer will generally remember the volume last used when you connect it to the same USB port.
