Operating The AFS2
Navigating & Modes Of Operation
There are three modes of operation in the AFS2, they are: Home Mode, Menu Mode, and Wizard Mode.
Home Mode
This is the operating mode which the AFS2 enters after power-up and initialization. There are two Home Screens which can be
viewed from Home Mode. To toggle between the two available Home Screens, just press the
DATA
wheel from Home Mode.
When viewing either Home Screen, turn the
DATA
wheel to select a filter. As each filter is selected, the channel and filter
assignment numbers for the selected filter will be displayed at the bottom of the screen. As each ‘set’ filter is selected, the
filter’s properties will also be displayed at the bottom of the screen. The filter properties displayed are:
•
Center Frequency –
This is the frequency of the center point of the filter.
•
Attenuation Amount –
This is the amount of attenuation applied at the filter’s center
frequency.
•
Q –
This is the width of the filter represented in ‘Quality’ factor or ‘Q’ factor. A Higher Q
value represents a narrower filter and a lower Q value represents a wider filter.

Menu Mode
In Menu Mode you can edit AFS options (these parameters are used when manually ringing out a sound system with AFS),
save and load presets, and edit system parameters. To enter Menu Mode, press the
MENU/BACK
button from the Information
View Home Screen. If viewing the Filter Plot Home Screen, you can enter Menu Mode by pressing and holding the
MENU/
BACK
button for approximately 2 seconds or pressing the
MENU/BACK
button twice. When navigating in menus, turning the
DATA
wheel will select on-screen options. In menus which have two columns, pressing the
DATA
wheel will jump between
columns, allowing you to jump back and forth between selecting the parameter to edit and then editing the parameter. Turning
the
DATA
wheel will adjust selected parameters. To see the menu structure and options available in these menus, see
’Menu
