This is the well-known 1 kW FM stereo transmitter from RVR. 

PRIMARY APPLICATION: high quality at a very attractive price. Ideal for use as transmitters in stand-alone applications. Adjustable power output from 10 to 100%.
HARDWARE FEATURES: compact, non-deformable and light thanks to the stainless steel chassis, in 2 rack units only.
USER-FRIENDLY FEATURES: four pushbuttons for user/device interaction and software that offers a simple, intuitive interface.
RELIABILITY/CONTINUITY: APC (Automatic Power Control) and Foldback protection ensure reliable operation under any operating conditions.
AUDIO PERFORMANCE: low distortion and intermodulation values and a high noise/signal ratio.
OPERATING EFFICIENCY: incorporate a PFC (Power Factor Corrector) power supply, that provides the utmost efficiency for enhanced energy saving and environmental protection, which added to LD-MOSFET technology ensure high efficiency, better than 70% across the bandwidth.
EASE OF MAINTENANCE: advanced module engineering ensures extreme of access and simple maintenance. Includes an high performance air filter. The power supply is plug-in type, easily removable.
INTERFACE CONTROL: total control thanks to microprocessor easily programmed from menu with all key parameters displayed on LCD.
INPUT/OUTPUT INTERFACE: built-in high-performance stereo coder, L&R analogue audio inputs, Mono inputs, MPX composite signal and auxiliary inputs for SCA / RDS signals. TOSLINK, AES/EBU digital audio inputs are available as an option.
RDS APPLICATION: built-in RDS encoder with UECP standard functions (option).
REMOTE CONTROL: built-in telemetry system via GSM modem or via WEB/SNMP (option).
REGULATORY COMPLIANCE: state-of-the-art technology in full compliance with EC, FCC and CCIR standards.
