DexStar®
DexStar® AM In-Band On-Channel exciters offer an unrivaled experience in digital transmission. The result is a superior exciter that delivers “best-in-class” performance, functionality and simplicity—during and after the transition from analog to IBOC digital radio. The DexStar exciter incorporates exclusive features to ensure maximum performance and functionality in real-world environments. Its improved audio I/O, RF I/O, re-engineered digital upconverter, and all-new controller and user interfaces make this exciter a no-compromise choice for IBOC. Beyond its many advantages, DexStar is available with the exclusive ePAL® for maximum configuration flexibility. ePAL provides all of the required synchronization and sample rate conversion to the STL signal, delayed audio bypass switching and digital audio distribution. ePAL also allows for the addition of a second, optional DexStar exciter for full IBOC redundancy.

Flexiva DAX™
The Flexiva DAX™ transmitters deliver high-quality, solid design in the 1-6kW range. Accurate digital signal reproduction with low bit error rate is essential to maximizing digital coverage. That is why our engineers specifically designed Flexiva DAX transmitters to not only deliver exceptional linearity and bandwidth but to also deliver the cleanest analog sound in this power range and provide the most accurate reproduction of the HD Radio signal in the low power ranges. Flexiva DAX Transmitters use the WEB Remote System, tied to the station's LAN or directly to the Internet, to provide IP based control and monitoring. Flexiva DAX performs with a high-efficiency modulation technique called Digital Adaptive Modulation. This technology uses a digitally generated AM waveform with DSP based adaptive correction to give the user a high performance transmitter in a cost-effective platform. Digital Adaptive Modulation samples the modulated output and dynamically corrects for non-linearity. The result is the cleanest, purest analog or digital (DRM or HD Radio) signal in this power level. The Flexiva DAX™ family is made up of four different AM/HD/DRM transmitters, which provides superior HD Radio™, DRM™, and analog performance.

Flexiva 3DX®
The Flexiva 3DX™ family — comprising 25, 50 and 100 kW models — provides exceptional performance, efficiency and peace of mind. Flexiva 3DX digital, solid-state AM transmitters features Direct Digital Drive (3D) technology, which provides a host of capabilities and benefits, including elimination of the RF driver section. This enhancement results in simpler design, greater efficiency and improved reliability — ultimately reducing operational costs. In addition, comprehensive diagnostics, which show exactly how the transmitter is performing at all times, along with hot-pluggable power amplifier (PA) modules and unprecedented redundancy, make all three models of the Flexiva 3DX family exceptionally easy to service. Complete IP-based control and monitoring of Flexiva 3DX transmitters in any location is possible by using the WEB Remote system tied to the station's LAN or directly to the Internet. And because all Flexiva 3DX transmitters are digitally modulated, transitioning to DRM™ or HD Radio™ is effortless. Simply add the appropriate exciter, and Flexiva 3DX is on the air in digital broadcast mode.
TX25 Plus & TX250 Plus FM Transmitters
THE TX 25 PLUS AND TX 250 PLUS FM EXCITERS ARE DESIGNED TO ACCEPT STEREO MONO MPX AUDIO SIGNALS TO BE MODULATED IN FM AND TO AMPLIFY THE RF. THE TX 25 PLUS AND TX 250 PLUS FM ARE EQUIPPED WITH AN INNOVATIVE AND HIGH-PERFORMANCE POWER SUPPLY STAGE «SWITCHING-MODE MAINS DIRECT», WITHOUT MAINS TRANSFORMER (THE MAINS VOLTAGE CAN VARY FROM 80 TO 265 VAC WITH NO VARIATION ON THE OUTPUT POWER).
