Los Angeles, CA. Crown Broadcast will be showing off a new FM transmitter package in their booth at World Media Expo, at the Los Angeles Convention Center this week. The 2KW package combines Crown’s transmitter technology with a full-featured exciter, a new DC power supply and a 2 KW amp.
“We have gained quite a reputation for modular and reliable FM transmitters in the low power ranges,” commented Ben Dorsey, Information Manager for Crown Broadcast. “With this new package, we hope to demonstrate our commitment to higher power applications.”
The key distinguishing feature of the 2KW package is its efficiency. The broadband amplifier is 75-80% efficient across the band with no field or factory tuning required. It features a responsive protection mode where problems with output devices, over-temperature, high SWR, or high current simply reduce the output power to a safe level until repairs take place. In addition, the amplifier has hot-swappable 500-watt power modules.
The amplifier itself is only 4 rack units high and weighs less than 50 pounds. The separate DC supply is power factor corrected and provides 90% efficiency. It is 3 rack units high and weighs less than 40 pounds. There are only three connections between the supply and amplifier and both are designed to be easy and intuitive to operate.
The modular package can be used with a bundled Crown Broadcast exciter, or the Crown amplifier/supply can be used with a station’s existing exciter/IPA. A compatbible 1KW package is due to be introduced soon.
