Features
RVR's PTXLCD is the most sold FM transmitter world-wide!
Building on RVR's long-standing expertise in the broadcasting
equipment industry, PTX exciters are designed to meet the needs
of the most demanding professional radiobroadcasting operators.
> AUDIO PERFORMANCE: PTXLCD's clear and transparent sound
quality is comparable to CD sound quality!. PTXLCD has been
designed using the latest state-of-the-art technology to achieve
superior sound quality thanks to a noise/signal ratio as low as
90dB!, low distortion and stereo separation as high as 60dB!.
> PRIMARY APPLICATION: RVR's PTXLCD series includes an
exhaustive power range for use as an independent exciter with
stepless power output adjustment from 0 Watt to maximum
output power.
> INTERFACE CONTROL: totally microprocessor-controlled, easily
programmed from menu or via RS232, RS485 and I2C interface
with all key parameters displayed on LCD.
> SW APPLICATION: it incorporates an analogue and digital
source acquisition board with stereo encoder and integrated
digital/analogue audio exchange. S/PDIF, TOSLINK, AES/EBU
digital audio inputs are available as an option on all PTXLCD.
> 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.
> REMOTE CONTROL: advanced built-in telemetry system enables
alarm transmission and SMS command reception through external or integrated GSM modem. The GSM modem is available as an
option.
> RELIABILITY/CONTINUITY: business continuity is guaranteed
by an incredible range and variety of controls, such as Fold-Back
control for effective VSRW (Voltage Standing Wave Ratio) protection and IAMLC (Intelligent Automatic Modulation Level
Control) to keep modulation level steady.
> EASE OF MAINTENANCE: advanced module engineering ensures
extreme ease of access and simple maintenance.
> RELIABILITY/CONTINUITY: a 24V DC connector connected to a
battery or other power source enables full-power transmission in
the event of mains failure (option).

Caratteristiche
IL PTXLCD RVR è il trasmettitore FM più venduto al mondo!
Gli eccitatori della famiglia PTX sono il frutto dell’esperienza pluriennale RVR nel settore Broadcast, concepiti per soddisfare gli operatori professionali più esigenti del mondo della radiodiffusione.
> AUDIO PERFORMANCE: il PTXLCD ha una chiarezza ed una limpidezza del suono paragonabile alla qualità CD! Il PTXLCD è stato
progettato allo Stato dell’Arte per ottenere una superba qualità del
suono, resa possibile da un basso rapporto segnale/rumore 90dB,
da una bassa distorsione e ad un’alta separazione stereo 60dB!
> PRIMARY APPLICATION: la serie PTXLCD della RVR offre una
gamma completa di potenze per l’applicazione come eccitatore
indipendente con potenza di uscita regolabile con continuità da 0
Watt alla potenza massima erogabile.
> INTERFACE CONTROL: completamente controllati da microprocessore, facilmente programmabile da menu o via RS232, RS485 e
interfaccia I2C, lettura su display LCD di tutti i parametri principali.
> SW APPLICATION: integra una scheda di acquisizione di fonti audio analogici e digitali con encoder stereo e scambio audio digitale/analogico integrato. Gli ingressi audio digitali S/PDIF, TOSLINK,
AES/EBU sono disponibili opzionalmente su tutti i PTXLCD.
> INPUT/OUTPUT INTERFACE: stereo coder integrato ad elevate
prestazioni, ingressi audio analogici L&R, mono e segnale composito MPX ed ausiliari per segnali SCA / RDS.
> REMOTE CONTROL: tramite un sofisticato sistema di telemetria
integrato è possibile l’invio di allarmi e ricezioni di comandi SMS
con modem GSM esterno o integrato. Il modem GSM è venduto
opzionalmente.
> RELIABILITY/CONTINUITY: la continuità di servizio è garantita
da un’incredibile gamma e varietà di controlli come il controllo
del Fold-Back per una effettiva protezione del VSRW (Voltage
Standing Wave Ratio) e IAMLC (Intelligent Automatic Modulation
Level Control) per un costante livello di modulazione.
> EASE OF MAINTENANCE: estrema accessibilità e semplicità di
manutenzione grazie ad una avanzata ingegnerizzazione modulare dell’apparato.
> RELIABILITY/CONTINUITY: la presenza del connettore 24V CC
collegato a una batteria o fonte di alimentazione alternativa, permette all’apparato la trasmissione in piena potenza anche in caso
di interruzione dell’alimentazione di rete (versione vendibile
opzionalmente).

RS232 connector
Serial RS232 interface can be used to connect the PTXLCD exciter to the service PC of the local manteinance
operator or, via modem, to the remote Technical
Assistance Centre. Different configurations can be made
for Telecontrol and Telemetry purpose.
Telemetry connector
8 analog input sockets, 2 relays output terminals and a
I2C bus interface are the telemetry connectors available
which data are displayed either on the LCD or on the PC
monitor.
Remote connector
Two signal input sockets for the control of “foldback”
output power are present on this connector: Direct and
Reflected Power Signal.
By adjusting the RFL trimmer, the Reflected Power
Threshold level (Reflected Fold-Back) can be regulated:
the exciter supplies the maximum possible Direct Power
so that the Reflected Power never exceeds the pre-set
level. In this way, the transmission signal continues to be
present, albeit more weakly, even in the event of very
high VSWR levels (a typical example is the presence of ice
on the antenna).
By adjusting the FWD trimmer, the Direct Power Threshold
level (Forward Fold-Back) can be regulated: the modulator
stabilises the Forward Output Power within 1dB in AGC.
This function is especially useful when the system
includes tube amplifiers which are subject to output
power variations in the event of fluctuations of the main
voltage.The remote connector has 6 analogue input sockets and 2 relay output terminals.These signals are used to
read measurements and to perform the on/off functions
of the RF Power Amplifier.There is also a I2C line for data
transfer with other equipment (RVR’s TLC300, SCM4,
TLC2000, etc.).
Personal computer link-up
It is possible to read and adjust through RVR's
Supervisory Software all the exciter's settings by linking
the exciter to a PC (either directly or by means of a telephone/radio modem). The System Manager can select the
settings to be accessed by the user. Different properties,
such as visible-yes/no, modifiable-yes/no, name, maximum level, unit of measurement, etc., for each setting
can be adjusted. RVR's Supervisory Software allows to
use customized configurations for Type and Format of the
data to be displayed. A telephone directory with name,
number and automatic dialling of all stations makes it
possible to set up a control and Supervisory System for a
specific geographical area.

Hardware Highlights
DIGITAL-IN Features
RVR's PTXLCD exciter was carefully designed to have superior parameters and operating stability. Several details
permit to reach the state of the art. The audio inputs are
equipped with RF filters and protection circuits all housed
in a metal box. The connections between the box and the
audio input board are by means of through-pass capacitors, ensuring that RF or any other kind of interference on
the cables are discharged onto the Exciter casing. The
total shielding of audio signal and RF circuits guarantee
the quality of the radio-electric characteristics S/N,
Spurious, etc. as well as full electromagnetic compatibility with other equipment.
> Input card for the acquisition of Analogue and
Digital Audio Signals with automatic changeover.
> A simple way to use digital audio signals on PTXLCD
exciters.
> Support of S/PDIF, AES/EBU (32 to 96 kHz sampling
frequency) and EIAJ CP340/1201 data format.
