User Controls
The user interface for the ADA4 is a 4-switch DIP
accessible through a cut-out in the bottom of the
unit, and an internal 3-position jumper block
accessed by removing the ADA4 cover (secured by
4 screws). Use the jumper to configure the mode of
operation (
Normal
or
Synchronizer
).Then use the
DIP switches—if necessary— to configure
channels and audio levels.
The exact function of the jumper settings and each
DIP switch are described on the following pages.
Factory default switch settings are all in the
leftmost position.
