The first 4O3A commercial amplifier. Continuous frequency coverage from 1 to 30MHz. Our TWIN topology provides guaranteed uptime through redundancy.If one out of the two RF modules fails for whatever reason, the amplifier will still remain on air uninterrupted, keeping half power through the second RF module. The damaged module can be hot swapped with a new one with absolutely no downtime.

The revolutionary TWIN topology offers ultimate flexibility for your radio station, transforming with a press of a button to match your desired configuration.
Combine the two modules into a single powerful amplifier, delivering 3500 watts of power in SO2R configuration.
