ENGINEERING INCORPORATED Sound Quality. Sound Engineering. PAC24 Technical Data Sheet P A C SERIES AUDIO CONTROLLER/INTERCOM SYSTEM Nobody knows audio control like PS Engineering. Now PS Engineering brings that level of expertise where it is needed most, professionally flown aircraft. The PAC24 was designed from the bottom up as a powerful audio system to meet the needs of airborne law enforcement, EMS, forestry, and special mission aircraft. Best yet, the revolutionary PAC24 is designed to be easily retrofit compatible into the same installation as a King KMA24H (-71). This makes adding modern, flexible, audio control and a high performance intercom into aircraft with aging audio panels easy and cost effective. The PAC24 contains PS Engineering's legendary IntelliVox® intercom, which eliminates squelch controls by using digital circuitry to sample each microphone independently, and distinguish between noise and voice. Proven in the harshest audio environments, like helicopters, it just plain works flawlessly. The headphone amplifier is the most powerful and cleanest in its class, delivering 120mW of punch to overcome the loudest cockpit environments. The PAC24 has all of the same features you expect from PS Engineering, like Swap™ mode (change radios by a push of a remote button), split mode (pilot and copilot on different radios), and a 3-year warranty. Designed from the beginning as a dual-capable system, the PAC24 offers outstanding flexibility for crew member and passenger communications. In a dual configuration, the pilot audio panel has command of the ships' audio if necessary, while the copilot side is able to handle any necessary audio chores. In cases where the crew wants extra control, the PAC24 can be switched to PTT-ICS mode.This prevents the intercom from activating until a discrete push to talk switch is activated. An "Observer” version of the PAC24 is also available. This unit allows radio transmission capabilities for a third person when configured as a special mission dual audio panel system. One audio panel provides Pilot and Copilot dual audio radio control, while the other audio control panel gives radio control to an Observer position. The transceiver controls are coordinated to prevent inadvertent transmissions, thus if the Pilot and Copilot are in Split mode (Pilot on COM 1 while Copilot is on COM 2), the system prevents the Observer from having access to COM 1 or COM 2, while allowing observer complete access to COM 3, COM 4 and COM 5. COM 5 has special properties in the PAC24. It can be configured as either a conventional Com 5 transceiver, or as a cellular telephone input. It provides full duplex telephone capability along with distribution of the telephone call. This allows either private or party line phone calls. And for those who are replacing order Bendix/King KMA-24H, the PAC24 is a slide in replacement.
