Early ATI controls

|Company||Acoustic Technology, Inc.|
|Type||Electronic Siren Controller|
In the 90s(maybe early 2000s?) ATI used a controller with this style for their sirens. It isn't clear what the HPSS-R series used, but at the very least the old "DSA" style ATIs used this controller. This controller primarily consists of an amp set with 4 removable amps, and a main board that handles the radio, tones, and other functions. Information in this board is extremely limited.
