Synthesized receiver from 830 to 1020 MHz The transmitter and recivered frequency can be easily setted by the internal dip - switches or by the front panel numerical selector (/C option). Excellent stereo separation. A built-in group delay and amplitude precorrector guarantees a very low phase distortion and a great stereo separation in the whole 15 kHz band. Suitable for digital audio. The subsonic overmodulation and the low frequency phase distortion are controlled by a feedback circuit in order to exalt the audio quality of the latest digital systems. Low THD distortion: the THD value with stereo or mono demodulated and deemphasized signals is negligible. Flat frequency response: due to the latest generation technology and the components precision the flatness of frequency response is absolute. Low noise: the excellent signal to noise ratio either in mono or in stereo allows the use of this STLs in multi hops networks without decreasing the audio quality. High sensitivity: it allows to reduce the STL's antennas investment. Great RF immunity: allows to operate in most hostile RF environments. High adjacent channel rejection: obtained thanks to the excellent mechanical shielding and the precision of RF filtering. High frequency stability with the internal temperature compensated crystal reference. Full metering: complete diagnostic and measurement front panel displays are available. Battery operations. VDC option is available for battery or solar panels operations.
Meets or exceeds all FCC and CCIR requirements.
