Operating your AVR250
For information display we recommend you use the OSD on your TV/screen whenever possible. However,
all key information is also duplicated one line at a time on the front panel display of the AVR250.
Switching on/off
Press the power button in. After approximately two seconds, the power LED will turn green and the
current input and volume level will be shown; after a further 10 seconds, the AVR250 is ready for use.
Please wait until the unit has nished initialising before attempting to operate the AVR250. It is
recommended that if the unit is switched off, you should wait at least 10 seconds before switching the
unit back on.
Stand-by
The AVR250 has a stand-by mode which can be entered by pressing the green stand-by button on the
remote control. When in stand-by mode the display is blank and the power LED glows red. If you do not
wish to put Zone 2 into stand-by at the same time as the main zone, press and hold the stand-by button
on the remote control for about 3 seconds. After this time, the front-panel of the AVR250 will display the
text “Main Off”, before going into stand-by; the LED for Zone 2 will be illuminated to show that Zone 2 is
still operating.
When not being used, the AVR250 may be left in stand-by mode, as power consumption is low. If you
are not using your AVR250 for several days, however, we recommend you switch the unit off completely
using the front panel power button.
To switch on from stand-by, press one of the source buttons on the front panel or on the remote control,
or use the stand-by button on the remote control.
Volume control
To adjust the volume level of the loudspeakers, pre-amp outputs and headphones use the volume
control knob. The volume level is shown on the display. Note that different sources may require different
settings of the volume control to achieve the same perceived volume level.
It is important to realise that the value indicated for the volume level is not an accurate indication of
the power delivered to your loudspeakers. The AVR250 may deliver its full output power long before the
volume control reaches its maximum position, particularly when listening to heavily recorded music. In
comparison, some movie soundtracks can appear to be very quiet, as many directors like to keep the
maximum levels in reserve for special effect sequences.
The volume can be controlled over a range of 100dB in 1dB steps.
Muting the volume
Pressing the MUTE button will mute the output of the AVR250 to the speakers and from the ‘pre-amp
out’ connectors (the output to the record loops remains unaffected). ‘MUTE’ will be shown on the display
while in this state.
Press MUTE for a second time (or adjust the volume) to exit the mute state.
Front panel display
In normal operation, the display shows the current volume setting, with the source shown on the left-
hand side of the display. Smaller illuminated areas indicate the audio input type (digital or analogue)
and the digital stream type (if applicable). If the processing mode changes (for example, from Dolby Pro
Logic decoding to Dolby Digital 5.1), then this will be displayed in large letters for about two seconds.
Changing the display brightness
It is possible to select the illumination level of the front panel display. Press DIS on the remote to cycle
through the three illumination levels (Off/Dim/Bright).
