5. DA2 USB Audio:

a. First, use only an appropriate well-sheilded certied USB 2.0* cable to connect

the DA2’s USB Audio input to any USB digital audio source component

(computer, laptop, media server etc.).

b. e DA2 USB Audio interface uses the B-type USB connector similar to

connectors used on printers. Please see image below:

c. Select the USB Audio input using front panel input selector buttons.

d. For MAC OSX systems, no driver is needed. OSX has the appropriate USB driver

already installed.

e. For Windows XP, Vista,Windows 7, 8.1 and 10 (32 or 64bit) systems install

the provided USB audio driver located on the soware CD in the folder named

“DA2 USB Audio Driver”. Read and follow the installation instructions.

f. Kernel, ASIO and WASAPI (Vista, 7, 8.1 and 10) drivers will be installed.

6. For Windows Media Player playback; in Windows Control Panel set the default sound

playback to the DA2 USB Audio device (Meitner Audio 2.0).

*Not using proper cables will cause audio issues between digital source and DAC.

7. In general for most audio applications you will be able to select the DA2 USB

Audio device (Meitner Audio 2.0) from within the application and choose the

appropriate ASIO, WASAPI or Kernel driver.

DSD and DXD Audio

1. e DA2 currently supports both DSD (DSD64), 2xDSD (DSD128) and DXD audio

streaming and conversion over USB. DSD streaming is enabled using DoP spec.

2. Please make sure that your DA2 has the latest installed rmware and drivers. If

unsure please email support@meitner.com with your DA2 serial number and our

engineers will be able to tell you if you need to update your unit.

3. DSD and 2xDSD audio les have the extension DFF and DST. DXD les are PCM 352

and 384kHz and are available in standard letypes like WAV or FLAC. You can use

any mediaplayer like JRiver and Audivarna to playback these les to the DA2.

4. Every media player will have specic soware installation instructions and setup

procedures for enabling DSD streaming. Please consult the specic soware manual.

5. Some soware manufacturers have also provided quickstart and soware setup

guides for download and online.

6. When setup correctly DSD and DXD samplerate types will be displayed on the DA2

display.
