2.5. Selecting one of the Factory Preset configurations
If the configuration at power-up is not suitable for your application, you may find that
another Factory Preset will be satisfactory.
2.5.1. Preview and select a Factory Preset
To view the text descriptions of the Factory Preset configurations:
Step 1 Select <A-D Modes> or <D-D Modes>
Step 2 Select <Factory Presets>
Step 3 Select each preset <1> to <4>
Check the description in the display. The LED above each button
will flash while in preview mode.
Repeat step 3 until you have chosen the store that seems most suitable.
Pressing the store button a second time will return the AD-2
unchanged to the normal operating state; alternatively this
control will time out and the unit will revert to normal
automatically after about 30 seconds without changing any
settings.
Step 4 To recall the store press [Enter].
If, having tried all of the stores, none is suitable you may either use the menu system
(see section 4.6) to create a fully-customized configuration, or for simple A-D modes
you may use the ‘Setup Wizard’ (see section 4.3).
2.6. Check the analogue line-up (headroom)
Connect a source of analogue audio to the inputs at the rear of the unit. Ensure that the
source is playing audio and check the meters on the front of the AD-2. A useful check
is to send a 0VU line-up tone. If all is well, this should illuminate the AD-2 meters up to
the -14dB division (in practice the LED at -14 may be on OR off for nearly exact 0VU
line-up with +18dBu headroom).
