Designed for the demands of both analog and digital transmission, the 4MX 25 transmitter is based on a patented modulation design developed by BE that packs unparalleled efficiency and features into a small footprint with a price to match.
Our next-generation 4M Modulation is a Fourier modulation design incorporating zero-voltage switching and modulated RF duty cycle enabling 4MX series transmitters to boast exceptional efficiency specifications. You can also operate the 4MX 25 at a power levels as low as 250 W to meet all your power level needs, day and night.
As little as one-third the footprint and weight of competing models, the 4MX 25 exceeds 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 at maximum power even with multiple failed modules. The power amplifiers are hot-pluggable and can be removed and replaced while the transmitter remains in operation.
The exciter in the 4MX 25 is DSP-based, providing enhanced audio performance by correcting for any distortion. Fully HD Radio and DRM compatible as delivered from the factory, the 4MX 25 accommodates both current and future versions of HD Radio. The 4MX 25 even provides the flexibility of changing transmission between analog-AM mode and analog-AM-plus-HD-Radio mode on the fly either locally or remotely.
