DAC-V1
Quick Start Guide
English
1. Introduction
The DAC-V1 is a six input digital to analogue converter and audio preamplifier designed
to handle audio from S/PDIF digital sources or directly from a computer USB interface.
When connected to a computer via USB, the DAC-V1 will behave as an external sound
output device and be accessible to a wide variety of audio playback applications.
The DAC-V1 incorporates stereo DIN and RCA phono analogue outputs, a front panel
6.3mm jack headphone output, and a volume control. DAC-V1 operation and setup is
achieved via its front panel controls and the supplied remote handset.
2. Installing and Connecting
Important:
If your DAC-V1 is to be used with a computer running Windows OS, the
DAC-V1 Driver application must be installed and configured in the Windows Sound Control
Panel before the DAC-V1 is connected via USB. Download the file, double-click on the
DAC-V1 Driver icon and carefully follow the installation instructions. The driver application
can be downloaded from: www.naimaudio.com/hifi-products/pdt-type/DAC-V1
• Stand your DAC-V1 on an appropriate, stable surface. Make sure it is well ventilated.
• Check that the
mains
supply specified on the DAC-V1 rear panel is appropriate for
your territory. Connect the DAC-V1 to the mains using the supplied cable but do not
switch it on until all other connections have been made and, if appropriate, the DAC-V1
Windows OS driver application has been installed on the USB connected computer.
• Identify the
Signal Ground Switch
and select the
chassis
option unless the
DAC-V1 is connected in a hi-fi system incorporating another earthed source component
(all Naim CD players, for example), or mains “hum” is audible through the loudspeakers
when the DAC-V1 is switched on.
• Connect one of the DAC-V1
analogue outputs
to a power amplifier or preamplifier
input as required. If the option is available on the pre or power amplifier, DIN socket
connections should be used in preference to RCA phono sockets. The DIN and RCA
phono socket options should not be connected or used simultaneously.
• If the DAC-V1 is to be used for the replay of audio files stored on a
computer
, connect
the computer, via one of its USB sockets, to the DAC-V1 using an A-B type USB cable. For
optimum audio performance the USB connection from the computer to the
DAC-V1 should be direct rather than via any “hub” device. The USB cable used should
be no longer than 3m.
Full DAC-V1 installation and operational information can be found in the Reference Manual available
at: www.naimaudio.com/support/manuals. The Window OS DAC-V1 Driver application can be found
at: www.naimaudio.com/hifi-products/pdt-type/DAC-V1

Note:
The DAC-V1 will only
function correctly with USB
2.x or 3.x interface sockets.
Note:
If your DAC-V1 is to
be connected to a futher
“downstream” preamplifier,
the DAC-V1 output volume
should be fixed by selecting
the Fixed Output option
in the Preamp Out setup
menu (see Section 4). If
headphones are used with
the DAC-V1 while Fixed
Output is selected, volume
control will be restored
while the headphones are
plugged-in.
Note:
The DAC-V1 Driver
application is compatible
with Windows Vista and
above only.
Note:
The DAC-V1 will only
function correctly with Mac
OS X versions 10.7.x and
above.
