Features / Benefits
The Harris ZX Series of transmitters offers the following useful features and benefits:
•
HD Radio capable with on-the-fly switching between FM, FM+HD, or HD mode
when used with FlexStar exciter.
•
Broadband design to eliminate tuning adjustments from 87.5 MHz through 108 MHz
(N+1 capable). Frequency change can be done electronically in seconds with Micro-
Max or FlexStar exciter or Digit exciter with external controller.
•
Redundant hot-plug RF amplifier modules allow module replacement while transmit-
ter is in operation.
•
Redundant hot-plug power supplies modules allow module replacement while trans-
mitter is in operation, including transmitter logic supplies. (each PS module has both
50V and 5V logic supplies)
•
Redundant cooling fans allow transmitter to operate at full power for extended peri-
ods with a fan failure, while fan tachometer alarm notifies service personnel of fail-
ure condition.
•
Three independent AC mains inputs per amplifier chassis and regulated power sup-
plies allow transmitter to accept a wide range of single or three phase mains power
without concern for line balance or rotation.
•
Redundant IPA amplifiers and PA splitters eliminate a single point of failure.
•
Non software-based controller for simple, repeatable operation. Does not require
UPS or battery to retain settings during AC mains failures.
•
EIA rack mounting for easy installation with only 16RU height for 5000W amplifier.
