            Main features:

            - Synthesized from 45-850MHz (specify 10MHz segment at the time of ordering)
            - The transmitted and received frequency can be set by digital front panel (UP/DOWN keys)
            - Suitable for MPX systems (stereo encoder in studio) or for 2-channel systems (2 audio channels, left+right, with 19KHz notch filter)
            - Built-in speaker driving amp for easy monitoring at the receiving side
            - 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 STL’s in multi-hops networks without decreasing the audio quality
            - High sensitivity: it allows for more range with smaller antennas
            - 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
            - Integrated LCD Display: complete diagnostic and measurement front panel LCD displays
            - Integrated information display and protection controls: for all transmit parameter and protection for malfunction

            Technical specs:



            - Transmitter is based on MAXPRO6000 so if you've used MAXPRO5000 or 6000 it will be very familiar to you
