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.
ENERGY-ONIX QUALITY
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 Pulsar transmitters use identical broadband power amplifier modules. Amplifiers are fully interchangeable within any 5KW Pulsar transmitter. This permits a standardized spare complement to be located at one flagship station. Each 2KW drawer contains (4) 500 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 (3) independent 2KW 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.
