that the remote control function overrides the
“autostart” dip switch function.
Setting the tone controls
The acoustic response of the system should
be adjusted to match the acoustic environ-
ment. The adjustment is done by setting the
five tone control switch groups ‘bass tilt’, ‘bass
roll-off’, ‘bass level’, ‘mid level’ and ‘treble
level’ on the amplifier panel. The manufactur-
er’s default settings for these controls are ‘All
Off’ to give a flat anechoic response. Figure 5
above shows the effect of the controls on the
anechoic response. Always start adjustment
by setting all switches to the ‘OFF’ position.
Then set only one switch per group to the ‘ON’
position to select the response curve required.
If more than one switch is set to ‘ON’ (within
one switch group) the attenuation value is no
longer accurate.
Maintenance
No user serviceable parts are to be found
within the loudspeaker cabinet or the ampli-
fier unit. Any maintenance or repair should
only be undertaken by qualified service per-
sonnel. Ensure that if fuse replacement is
required, only fuses of the same voltage and
current rating are used. Remember to dis-
connect the power supply by removal of the
mains cable, before fuse replacement.
Safety considerations
Although the AOW312 loudspeaker has been
designed in accordance with international
safety standards, to ensure safe operation
and to maintain the instrument under safe
operating conditions, the following warnings
and cautions must be observed:
1. Servicing and adjustment must only
be performed by qualified service
personnel. The amplifier must not be
opened.
2. Do not use the loudspeaker with an
unearthed mains cable or unearthed
mains connection as this may lead to
personal injury.
3. This loudspeaker is capable of
producing sound pressure levels in
excess of 85 dB, which may cause
permanent hearing damage.
4. A free flow of air around the amplifier is
necessary to maintain sufficient cooling.
Do not obstruct airflow around the
amplifier
5. To prevent fire or electric shock, do not
expose the unit to water or moisture. Do
not place any objects filled with liquid,
such as vases on or near the
loudspeaker or the amplifier.
6. Note that the amplifier is not completely
disconnected from the AC mains
service unless the mains cable
is removed from the amplifier or the
mains outlet.
