Efficiency greater than 93%, achieved through the use of Hexfet type power transistors in the design of the desalida circuits. The PWM modulation system and the intrinsically linear amplification circuits allow us to ensure a linear frequency response between 20 and 15,000 Hertz, with reduced distortion levels (less than 1%).

Solution represented by a DDS, integrated digital circuit, which directly synthesizes the desired frequency by programming it. This device is integrated in the control board, which is intended to accommodate two of these circuits and to change them automatically in case of failure of one of them (optional dual digital synthesizer).

In analog operation, thanks to the design of the main power source and the PWM circuits, our equipment is able to operate with modulations up to 150% at the positive peak, which translates into an excellent "volume on the dial". In hybrid operation, ie analog and digital simultaneously (IBOC), our equipment is capable of operating up to 125% modulation for the analog signal, considering a bandwidth of 8 KHz, plus digital modulation.
