It is important that Mac OS X is appropriately configured
for audio playback via the DAC-V1 however, no driver or
extra software installation is necessary.
Note:
The DAC-V1 will only function correctly with Mac OS
X versions 10.7.x (Lion) and above.
Note: When an OS X computer is first connected to a
DAC-V1, it may ask for specific key-stokes to be sent to
identify the "keyboard" layout. This is because the DAC-V1
behaves in part like a multimedia keyboard that can send
volume, play, pause, next, and previous commands to
the computer. The DAC-V1 keyboard setup menu enables
the appropriate identifying "key-strokes" to be sent. See
Section 5.2.6 for more information.
2.2.1 OS X Sound System Preferences setup
Once the DAC-V1 is connected via USB and switched on,
the OS X Sound System Preferences can be configured to
select the DAC-V1 as the default audio output device.
The OS X screen images and captions following illustrate
and describe selection of the DAC-V1 as the sound output
device.
• O pen the OS X System Preferences
Sound (located at the end of the Hardware row).
• O pen the OS X Sound
Output and click on DAC-V1 in the list of output
devices. Confirm the selection by closing the System
Preferences pane.

2.2.2 OS X Audio MIDI Setup
In addition to the setup of OS X Sound System Preferences,
an OS X application called

appropriately for use with the DAC-V1.

and describe configuration the OS X Audio MIDI Setup
application when the DAC-V1.
• G o to User/Applications/Utilities, find the Audio MIDI
Setup
application and double-click on its icon to start
it. If no application window opens go to the
menu and select

available audio devices and that the
highlighted. Drop-down menus beneath the Output
tab enable the selection of
depth
to match the audio files to be played. Select
24 bit, 44100Hz as the default.
Note: The need to configure OS X Audio MIDI Setup is
dependent on the audio playback application used. If
iTunes is used, Audio MIDI Setup should be configured
as described above, however some alternative OS X
audio playback applications, BitPerfect for example,
do not access Audio MIDI Setup during audio playback
so its configuration is unnecessary. DAC-V1 playback
application notes that cover more detailed OS X
configuration, including the Audio MIDI Setup application,
can be found at: www.naimaudio.com/knowledge-base
Note: The BitPerfect audio playback application is
available from the Apple App Store.

alert audio played through the DAC-V1, ctrl-click or left-
