General description
The latest and most powerful system in our range, the ECRESO FM 5 kW and 10kW transmitters offer a truly
revolutionary approach to high power FM transmission.
With all the key advantages of the core ECRESO range, the ECRESO FM 5kW and 10kW add a whole new dimension of
reliability, redundancy and overall efficiency. The power amplifiers, power supplies and even the fan modules are fully
hot swappable and redundant and a completely passive 6-way coupler ensures that, should one of the amplifiers
suffer a fault, the transmitter can stay on-air with minimum power loss indefinitely until the fault is rectified. The
highly efficient, self-monitoring power supplies contribute to an overall transmitter system efficiency of up to 76%, the
highest available in today’s FM broadcast market.
The unique architecture and innovative design ensure ease of access, ease of use and ease of maintenance.
Like with all ECRESO FM transmitters, top signal qu
ality and performance are achieved thanks to the “FM Band Direct
to Frequency” digital modulator which is at the heart of this range.
Ecreso FM transmitters are fully protected against overheating, VSWR and lightning.
They also offers a number of built in functions that can eliminate the additional cost and space requirements of
external equipment.
Fully featured for local maintenance and configuration, they also allow full remote control by Web server, SNMP,
RS232 or GPIO (GPIO as option).
Options available with the current version are:
•
SmartFM
: developed over 3 years of intense research, this option makes it possible to enhance the listening
experience, reduce FM Operating Costs (Opex) and reduce CO
2
emissions.
•
RDS
: the internal RDS encoder makes it possible to manage RDS parameters (PI, PS, TP, TA, PTY, MS, DI, RT,
PTYN, AF, CT) and includes 1 PSN and 2 DSN.
•
5-band Sound Processor
, which includes:
o
Single digital processing from audio to RF (direct to frequency)
o
Low Latency and Powerful DSP based algorithms
o
Gated and predictive automatic gain control
o
Equalization, Bass and Treble Enhancers
o
Stereo Enhancer and Limiter
o
5 Band Processors
o
5 Band Limiters
o
HF and Final Limiters
o
Complete set of audio presets
o
Intuitive and complete user interface with settings and vu meters (web based)
o
Easy fine tuning of your sonic signature
•
SFN
: this option includes a 10 MHz input to synchronize the RF sub-carrier to an external source and an
embedded memory on the digital modulator to configure the delays which will allow to the synchronization
between the various transmitters.
•
GPIO
: additional board
(standard digital, analog or digital with “fault memory”)
which allows remote control
and management of your transmitter. Available as standard or analog board.
