NAIM DAC – English
2.2 S/PDIF Inputs
The eight rear panel S/PDIF inputs are provided with
connection format and socket options. These are listed in
the following table:
Input Optical Socket Coaxial Socket
S/PDIF 1 TOSLINK BNC (75Ω)
S/PDIF 2 TOSLINK BNC (75Ω)
S/PDIF 3 TOSLINK RCA phono
S/PDIF 4 TOSLINK RCA phono
Only one connection format (optical or coaxial) for
each input may be used at any one time. However,
both may be connected simultaneously and the DAC
will automatically select the socket on which valid data
is present. If a data stream is present on both sockets,
selection can be switched between the two by pressing
the relevant input button.
Note: If valid data is present on both the coaxial and
optical sockets of the selected input, the stream that
appeared first will be preferred.
2.3 USB Inputs
The front and rear panel USB sockets are for the
connection of either USB memory sticks or Apple iPod or
iPhone models. Connect iPod and iPhone models using
the standard Apple USB cable. When USB hardware is
connected the DAC will automatically switch to the
docked USB input.
Note: If both USB inputs are docked, the front panel input
will take priority.
The DAC is able to handle any audio file format that can
be played on the Apple device, however, a lossless format
will provide the best audio quality.
2.4 Analogue Outputs
The DAC is fitted with both DIN and RCA phono analogue
output sockets. The DIN option will provide the best audio
performance. Set the rear panel Socket Selection switch
to the desired option. For best audio performance only
connect one audio output. If the DAC analogue output
is to be connected to a Naim preamplifier, use the Aux 1
input if available. See Section 3.1.
2.5 Remote Control Output and Input
The DAC can send and receive remote control signals to
enable the following functions:
• Automatic preamplifier input switching.
• Use of an external IR sensor.
The DAC Remote Control In and Out sockets require a
mini-jack (3.5mm) plug. Naim preamplifier Remote Control
In sockets require either a mini-jack or RCA phono plug.
Your Naim retailer will be able to provide an appropriate
cable if necessary.

2 DAC Installation and Connections
The DAC should be installed on a dedicated equipment stand intended for the purpose.
Do not stand it directly on top of another item of equipment. Ensure also that the audio
system volume is turned down before switching on. The DAC power switch is positioned on
its rear panel.
Connect the DAC to mains power using the mains cable supplied or a Naim Power-Line.
Connect audio inputs and outputs using high quality interconnect cables. Naim Hi-Line
cables will provide the best results.
