TEX LCD 30 | 50 | 100 | 150 | 30030NV FM exciter
High performance exciters, compact, reliable and easy maintenance.
Broadcast quality at a value price, can be used as drivers for medium
power FM stations or as stand-alone applications.
Compact, non-deformable and light, 2HE rack unit, stainless steel chassis.
High performance integrated stereo coder, with L&R Mono and MPX inputs and 2 SCA / RDS signal inputs.
Continuously adjustable output power from 0 to maximum power with automatic APC control and Foldback protection. Safe operation in any working conditions.
Completely microprocessor-controlled easy to program from the menu or via RS232, all main parameters can be read on the LCD display.
Possibility to be monitored through all RVR telemetry systems to guarantee simple remote control of the operating parameters.
Manufactured using SMD technology and composed of only 4 modules. Maximum operating reliability designed to allow an easy maintenance.
Universal multi-voltage power supply from 80 to 260 V with no preselection. Modern technology that complies with all EC, FCC and CCIR standards.
These TEX LCD are exciters for Frequency Modulated audio broadcasting in a frequency modulation able to transmit in the band between 87.5 and 108 MHz, in step of 10 KHz, with an RF output power into a 50 Ohm standard load.
They are designed to be contained in a 19” rack box of 2HE.
These FM exciters contain a low-pass filter that reduces the harmonic emissions to below the limits allowed by international regulations (CCIR, FCC or ETSI), and can therefore be used as a transmitter connected directly to the antenna.
The outstanding audio features of these devices is the low distortion and intermodulation values and the high signal to noise ratio in mono operation.
Another important feature of these TEX LCD FM exciters is its great simplicity of construction and use.
They are designed to be modular. The various functions are run from modules directly connected to each other with male and female connectors or with flat cables ending in connectors. This type of design makes maintenance operations and any required module replacement easier.
The RF power section uses one MOSFET module able to deliver from 30 to 300W depending on the model.
The working frequency is assured by a thermally-compensated, reference oscillator working within a phase-locked loop (PLL). Frequency lock is reached within a maximum of 30 seconds.
These fm exciters are able to work in all range frequencies without calibration and setting operations.
The microprocessor system includes an LCD display and push-button panel for interaction with the user, and implements the following functions:
Four LEDs indicate the machine status and are found on the front panel: ON, LOCK, FOLDBACK and RF MUTE.
The exciter’s management software is based on a menu system.
The user can navigate between the various submenus by using four push buttons: ESC, , and ENTER.
On rear panel there are Mains connector, with a votage selector that allow to use different mains voltage (Full range version), audio input and RF output connectors, telemetry connector, protection fuses, two inputs for modulated signals on subcarriers from special external encoders normally used in Europe for RDS (Radio Data Systems) transmission.
RVR produces broadcast equipment: FM transmitters, broadcast transmitters, FM amplifiers, FM exciters, TV transmitters, cavity filters and combiners, radio links, and other FM broadcasting products for radio and television stations. Our exciters include both analog and digital models. We have both Solid state and Tube transmitters and amplifiers.
