4.5.4. Editing the text description of a user store
This is performed by first loading the store as described in section 4.5.1 and then
saving it with your new text description as described in sections 4.5.2.2 and 4.5.2.3.
4.6. Menu system operation
The Menu system of the AD-2 provides access to all operating parameters so that
custom configurations of both A-D and D-D modes can be created and preferences
such as LED brightness and LCD contrast (and others) can be set.
It is advisable to store a custom configuration once it has been created.
Section 4.5 explains the procedure for storing your settings.
All the control settings are saved in permanent memory so that they are remembered
when the unit is off.
4.6.1. Normal Display - Peak Level indications
The normal display of the AD-2 once powered and initialized is:
Level: dBFS
< llll <> rrrr >
Where llll and rrrr are the peak amplitudes for the left and right channels,
expressed in dBFS (decibels relative to digital clip level). These are normally
displayed using a zero-attack peak hold algorithm with automatic decay to zero.
Indefinite peak hold is available and may be selected by pressing [Enter] at the normal
display level. The level units indication will change from dBFS to HOLD and back for
subsequent operations.
The ‘HOLD’ settings also applies to the Program Meter display. See section 4.4 for
more detail.
