RVR Elettronica PTRL-LCD STL Transmitter

Overview Specifications

Synthesized from 48 to 1020MHz ( in factory set band segments).
The transmitted and received frequency can be easily set by the internal dip - switches or by the front panel numerical selector (/C option).
Excellent stereo separation. A built-in group delay andamplitude precorrector guarantees a very low phasedistortion and a great stereo separation in the whole 15kHz band.
Suitable for digital audio. The subsonic over-modulation 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 STL in multi-hop networks without decreasing the audio quality.
High sensitivity: It allows one to reduce the STL's antennas investment.
Great RF immunity: Allows one to operate in the most hostile RF environments.
High adjacent channel rejection: Obtained thanks to the excellent mechanical shielding and the precision RF filtering.
High frequency stability with the internal temperature compensated crystal reference.
Full metering: Complete diagnostic and measurement frontpanel displays are available.
Battery operations. VDC option is available for battery or solar panels operations.
Meets or exceeds all FCC and CCIR requirements.
