4MX Series (25kW to 100kW) - 4MX 100 (D)



100 kW AM Transmitter

Looking for big power in a small footprint? The 4MX 100 delivers up to 100 kW at 87% efficient while exceeding expectations for reliability and service accessibility. The unique design directly connects efficient switching power supplies to the power amplifier, entirely skipping the modulator stage. 
All power amplifiers have their own power supply, producing unparalleled redundancy, thus ensuring the transmitter is on air even with multiple failed modules. The power amplifiers are hot-pluggable and can be removed and replaced while the transmitter remains in operation. 
The 4MX 100 comes standard with a DSP-based exciter, providing enhanced audio performance by correcting for any distortion. In addition to superior audio quality for your listeners, the 4MX 100 offers unprecedented diagnostics, such as the ability to view an impedance sweep of the antenna system, as well as a spectrum analysis of the output signal to verify spectral performance of analog AM and HD Radio systems. 
Full transmitter control and diagnostic capabilities are available locally via a 15-inch, 1024 x 768 XGA front-panel display. The user interface provides intuitive soft-button operation for easy viewing of all pertinent transmitter status and advanced diagnostic information, as well as transmitter operational control. 
Fully HD Radio and DRM compatible as delivered from the factory, the 4MX 100 accommodates both current and future versions of HD Radio. As you have come to expect from BE, the 4MX 100 provides the flexibility of changing transmission between analog-AM mode and analog-AM plus-HD-Radio mode on the fly either locally or remotely. When it comes to implementing HD Radio, no AM transmitter provides more system design options than the 4MX 100.
