2 Switch On and Input Setup
2.1 AV2 Switch On
Once all signal connections are made the AV2 can be
switched on. Connect the AV2, using the supplied mains
cable, to an appropriate mains socket and operate the
power switch on the rear panel. A single flashing dot will
be seen on the display while the AV2 starts-up. The dot
will stop flashing to indicate that the AV2 is ready for
use.
When initially switched on the AV2 will be in Standby mode.
Standby is indicated by an illuminated Naim logo and a single
dot indicator on the display. To wake the AV2 from standby
press the handset
standby
key or the front panel
input
or
mode
buttons. The AV2 will wake-up in either the default state if it is
previously unused, or in the state in which it was last shut-down.
2.2 AV2 Input Setup
The AV2 Input Setup routine defines input names, turns-off any
unused inputs, and sets some control and decode parameters.
To switch the AV2 into Input Setup mode press the handset
menu
key followed by the
input
key, or press and hold the front
panel
input
button. The front panel
input
button will flash.
To scroll down or up the setup parameters press the handset
6
or
5
keys or the front panel
input
or
mode
buttons.
To select a setting for each parameter press the handset
3
or
4
keys or use the front panel rotary control.
The diagram opposite shows the list of input setup parameters
with some typical settings chosen. In this example, a VCR is
nominated for input AN1, a CD player for input AN2, a Satellite
Receiver for input OP1, and a DVD player for input CO1. All the
other inputs are turned off and both the remote handset control
and Pro Logic II parameters are left at their default settings.
To return all input setup parameters to their default state press
and hold the handset
disp
key while the AV2 is in input setup
mode.
To exit from Input Setup mode press the handset
menu
key
followed by the
input
key, or press and hold the front panel
input
button.

3 Speaker Setup
3.1 AV2 speaker setup
The AV2 Speaker Setup routine both defines the
presence and type of speakers to be used in the system
and sets their listening distance and volume level
parameters.
To switch the AV2 into Speaker Setup mode press the handset
menu
key followed by the
mode
key, or press and hold the front
panel
mode
button. The front panel mode button will flash.
To scroll down or up the setup parameters press the handset
6
or
5
keys or the front panel
input
or
mode
buttons.
To select a setting for each parameter press the handset
3
or
4
keys or use the front panel rotary control.
The diagram opposite shows the list of speaker setup
parameters with some typical settings chosen. In this example,
large (full bandwidth) front speakers, a large centre speaker,
small (restricted bandwidth) surround speakers and a sub-woofer
have been specified.
Distances in metres from the speakers to the listening position
have been specified and relative volume levels between the
speakers have been adjusted using the test signal. Distance and
level parameters for extra rear speakers don’t appear because
they have been specified as not used.
To use the speaker test signal, set the AV2 volume to a
moderate level (use the handset
vol
6
and
vol
5
keys - a value
of 40 - 50 should be fine) and set TST to ON. Press the handset
6
key. A noise signal should be heard from the left front
speaker.
Listen to the noise through each speaker (handset
6
key) before making any adjustments - this will confirm the
speaker connections are correct and reduce the possibility of
unnecessary volume level adjustments being made.
Listen to each speaker once again (the AV2 user interface
cycles around the speaker volume level setup stages) and adjust
the levels so that each one is equally loud from the normal
listening position. In the example diagram the centre channel
has been adjusted upward slightly while the surround channels
have been lowered. The sub-woofer volume level is best set
somewhere between the highest and lowest levels for the other
speakers and then adjusted using its volume adjustment.
To return all input setup parameters to their default state press
and hold the handset
disp
key while the AV2 is in input setup
mode.
To exit from Speaker Setup mode press the handset
menu
key
followed by the
mode
key, or press and hold the front panel
mode
button.
