RTX19/1
FM BROADCAST RECEIVER
87.5 ÷ 108 MHz
INTRODUCTION
The RTX19/1 Receiver is the latest result of the experience gained by SIELCO (formerly SIEL) during
years of producing FM broadcast equipment, transmitters, stl and stereo encoders.
This Receiver is specifically designed to be used in the harsh and noisy environment of a broadcast site
discriminating week signals in a crowded spectrum, filled with strong interfering signals to provide high quality
modulation for a local FM repeater transmitter.
Great care was spent into producing a Hi-Fi-quality modulated signal, with low residual noise and
distortion. Notwithstanding the robust interference management capability, adequate care must be provided
to protect the received signal from strong local interfering signals on the FM band coming from on site
transmitters. This can be usually accomplished by using a top quality directive antenna and RF cable which
must be mounted as much as possible far from the transmitting antennas. In the worst cases an external passive
high Q tuned filter mast also be adopted.
To verify this requirements in order to obtain outstanding performance, SIELCO strongly recommend to
rely on qualified personnel to install and verify the equipment which makes up the receiver installation and all
the radio station. This will assure to achieve the best performance and stability in time.
To this aim, SIELCO especially recommend that their equipment should not be tampered with by unskilled
personnel and its after-sale service is available to customers for any technical problem. Before proceeding
to installation, please carefully read at least the general installation part of this manual, to gain confidence with
the equipment.
This equipment is very stable and changes to the internal pre-setting other than frequency and few other
options are not usually required but, if they are, once again they must be done by skilled personnel, with proper
instrumentation and service documentation. Improperly tampering with the settings may harm the apparatus
or jeopardize the guaranteed performance.
THIS EQUIPMENT COMPLIES WITH ALL RELEVANT
EMI/EMC AND SAFETY
REQUIREMENTS,
ETSI EN300454-1/2 AND ETS301489-01/11
STANDARDS.
NO INTERNAL ADJUSTMENT OR PRESETTING IS REQUIRED DURING NORMAL
OPERATIONS. THE APPARATUS SHALL BE PROPERLY EARTHED AND BE OPERATED
WITH ALL THE COVERS CLOSED TO PREVENT ELECTRICAL HAZARDS AND COMPLY
WITH EMC STANDARDS.
