Energy-Onix Pulsar transmitters are the most ruggedly-constructed, solid state AM transmitters available today. Designed for survivability in the most severe environments, Pulsar transmitters offer the combination of long-term reliability, unsurpassed audio performance and price economy made famous by Energy-Onix.

UNIVERSAL PA DESIGN

The solid state design is field proven in hundreds of applications. All medium and high power Pulsar transmitters use identical broadband power amplifier modules. Amplifiers are fully interchangeable within any Pulsar transmitter. This permits a standardized spare complement to be located at one flagship station. Each 2.5KW drawer contains (4) 630 watt modules.

DESIGNED TO KEEP YOU “ON THE AIR”

The Pulsar series is designed to remain “On The Air” in the unlikely event of a PA module failure. Remaining modules will continue to operate without any change in modulation capability. The transmitter contains (24) independent 2.5KW modules. In the event of a module problem, it will turn off, and the “inoperative” unit can be removed by simply sliding it out and then it can be troubleshot, returned to the factory, or can be replaced by a spare PA Drawer.

PULSAR ....... SOLID STATE PDM AM FOR THE REAL WORLD

We know that broadcasters demand reliability along with impressive features. To keep you “ON THE AIR”, every Pulsar incorporates extensive surge suppression and overload protection. A full range antenna line coupler is standard for less-than-ideal antenna systems. A simple, reliable conventional brute-force power supply is used with the hot-plugable power amp modules. Conservatively rated and cool running, the choice is Pulsar -- field proven by real broadcasters in the real world.
