AV2
16 AV2 Inputs and Interfaces
The AV2 has a total of ten audio inputs: six stereo
analogue and four digital. The analogue inputs are
connected through a combination of DIN and phono
sockets while two digital inputs are connected through
optical “TosLink” sockets and two through coaxial
phono sockets. A remote control RC5 input is also
fitted to enable remote control handset commands to
be relayed to the AV2. This feature provides enhanced
multi-room or concealed installation flexibility. The
RC5 input is selected during the Input Setup routine
described in Section 18. Your dealer or local Naim
Audio representative will be able to offer advice on its
use.
Analogue input sockets ONE and TWO are “versatile” sockets
that can be combined to enable the connection of source
components that already offer multi-channel outputs - DVD Audio
and Super Audio CD for example. When operating in combined
mode, eight or six input channels (available on the two DIN
sockets) are routed internally direct to the output volume control,
bypassing the internal signal decoding. Eight or six channel
combined mode is selected during the Input Setup routine
described in Section 18.
The input THREE socket also carries a stereo audio output signal.
If the AV2 is to be integrated into a conventional stereo audio
system this input/output socket should be connected either to
the system’s “tape monitor circuit” or in the case of a Naim
system to the appropriate preamplifier or power amplifier input
socket.
Note:
Integration of the AV2 with a conventional stereo audio
system may require a non-standard “reversed” connection cable. An
appropriate cable, identified by its yellow band, is included in the
AV2 document pack.
Each input socket and its appropriate connection is detailed in
Table 16.1. See the illustration in Section 22 for socket and pin
identification.
17 AV2 Outputs and Interfaces
The AV2 is fitted with line-level signal output sockets
for front left and right, centre, surround left and right,
extra rear left and right and sub-woofer channels.
The front, centre, surround and extra rear outputs are connected
through 4-pin DIN sockets and each of these should be routed
to appropriate Naim power amplifiers. The sub-woofer output
is connected through a single phono socket and should be
connected to either an active sub-woofer or a mono power
amplifier driving a passive sub-woofer. An alternative sub-woofer
output is available on the centre output socket.
The AV2 is also fitted with both analogue and digital audio
outputs. These outputs duplicate the selected input signal in
either the analogue or digital domain. No signal will be present
on the analogue output if a digital input is selected and similarly
no signal will be present on the digital output if an analogue
input is selected. The analogue outputs can be used to restore
the amplifier tape monitor outputs if these have been used as a
signal source for the AV2.
An interface connector fitted to the AV2 enables integration with
Naim DVD players. The interface is connected via a “telecoms”
style socket.On-screen display (OSD) of AV2 operational and
setup commands will be available if a DVD player is connected.
The interface socket should not be used for any other
application. Inappropriate use may cause damage to the AV2 or
other equipment to which the
socket is connected.
The multi-room interface socket
is a 9-pin RS232 type connector.
Multi-room interface functions
of the AV2 will depend upon
the capabilities of the multi-
room system and controller
in use. Your local Naim Audio
representative will be able to
offer advice on multi-room
features.
Each output socket and its
appropriate connection is
detailed in table 16.1. See the
illustration in Section 22 for
socket and pin identification.

Note: The 5 Pin DIN socket of Input 3 also carries stereo audio outputs. Input 3 should be used to
connect the AV2 to an existing Naim system.
Note: The digital optical input sockets are fi tted with protective plugs that must be removed before use.
