8.0 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 analog and digital audio outputs. These outputs duplicate
the selected input signal in either the analog or digital domain. No signal will be present
on the analog output if a digital input is selected and similarly no signal will be present
on the digital output if an analog input is selected. The analog outputs, connected via a
pair of phono sockets, can be used to restore the amplifier tape monitor outputs if these
have been used as a signal source for the av2 . The digital output, available in both phono
socket and optical TosLink formats, can be used to connect a digital audio recorder such
as a CDR machine (if the digital data format is appropriate).
Interface connectors fitted to the av2 enable synchronised video signal switching, and
integration with multi-room home entertainment systems. The video switch interface is
connected via a “telecoms” style socket. This interface is intended specifically for the Naim
vs1 Video Switcher. On-screen display (OSD) of av2 operational and setup commands will
be available if the video switcher is used. The video switch 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 dealer or local Naim Audio representative will be able to offer
advice on both multi-room and OSD features.
Each output socket and its appropriate connection is detailed in the following table. See
the illustration in Section 12 for socket and pin identification.

More! On Screen Display (OSD) of the av2 front panel information will be
available if a vs1 Video Switcher is connected to both the av2 and to an
appropriate TV monitor. Use of OSD is covered in section 10.7.
More! The digital optical output socket is fitted with a protective plug that
must be removed before use.
