Operation

Basic Operations and Input Connections

In general for most audio applications you will be able to select the DV2 USB

Audio device from within the application. en choose the appropriate drivers,

ASIO, WASAPI or Kernal, you want to use with it.

DSD, DXD and MQA® Audio

1. e DV2 currently supports DSD (DSD64), 2xDSD (DSD128), DXD and

MQA® audio le streaming and conversion over USB. DSD streaming is

enabled using DoP spec.

2. Please make sure that your DV2 has the latest installed rmware and

drivers. If unsure please email su[email protected]m with your DV2

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

(PCM 352 and 384kHz) and MQA® are available in standard letypes like

WAV or FLAC. You can use any mediaplayer like JRiver, Roon, Audivarna

or a standalone media/network player to play these les to the DV2.

4. Every media player will have specic installation and setup procedures

for enabling DSD, DXD and MQA® le streaming. Please consult its specic

soware manual.

5. Some soware/hardware manufacturers also provide quickstart and

soware setup guides.

6. When setup correctly samplerate and le types will be displayed on the DV2

display.

7. Depending on the digital source, when playback of DSD material is paused

or stopped the display may indicate a PCM samplerate rather than DSD.

is is normal for DoP functionality. Once playback is restarted the DV2’s

display will once again show that it is receiving DSD information.

8. e DV2 supports the full unfolding of MQA® audio les using its custom

implementation of the MQA® decoder and renderer.

9. Depending on the media player and source material, the display will show

the type of MQA® le (‘MQA’ or ‘MQA Studio’) and the maximum unfolded

sample rate. ‘MQA’ or ‘MQA Studio’ indicates that the product is decoding

and playing an MQA® stream or le, and denotes provenance to ensure that

the sound is identical to that of the source material. ‘MQA Studio’ indicates

it is playing an MQA® Studio le, which has either been approved in the

studio by the artist/producer or has been veried by the copyright owner.

MQA® (Master Quality Authenticated) is an award-winning British

technology that delivers the sound of the original master recording.

e master MQA® le is fully authenticated and is small enough to

stream or download.
