1.1 Introduction.
The
EM 1000 HE DIG PLUS COMPACT
transmitter is equipped with the most modern
technology available, to provide you with maximum performance at minimal performance
cost, while fully conforming to technical regulations. Flexibility, quality, compactness, and low
electrical consumption make the devices in the EM 1000 HE DIG PLUS COMPACT the best
offered on the market today.
These are just a few of the advanced characteristics that make the EM 1000 HE DIG PLUS
COMPACT truly unique:
•
Super-compact size and reduced weight
•
Low performance costs.
The unique design reduces internal loss and allows the device to
achieve an extremely high yield – typically greater than 80% - minimizing electrical
consumption and thus decreasing performance costs.
•
Sturdy modular construction
. Reliable modular construction minimizes and facilitates
maintenance operations. In addition, it ensures a greater average time between failures, as
well as ease of maintenance.
•
Easy to use and to configure.
The transceiver uses a control interface, which is equipped
with a large LCD screen, a multifunction knob, and few other buttons. This allows the user to
easily set functions on the device, and to view the operating parameters in the blink of an eye.
•
Nominal RF output power over the full FM range particularly stable against time.
The
output power may be varied from a minimum level and the operating frequency includes the
full FM range, without retouching other parameters.
•
Power section entirely modular and highly reliable.
•
RF output stage has a reverse intermodulation figure lower than the standard bipolar
construction
. Low enough to approach that of tube equipment, due to the MOS-FET design.
•
Low level of dissipation.
The reduction in internal loss and overall elevated yield minimize
the dissipation of heat; as a result, the devices in the EM 1000 HE DIG PLUS COMPACT
perform well even in challenging environmental conditions.
•
Stable, reliable power supply.
The entire line of transmitters integrates the use of power
sources with active power factor correction (PCF), as stipulated in recent regulations. As such,
impact on the electrical power source is minimal, resulting in greater reliability over the entire
device.
•
Easy diagnostics and easy-to-read parameters
, thanks to a comprehensive metering and
alarms section on the LCD display. All parameters and alarms are easily accessible from
remote posts via the remote control input, which allows the user to change from stand-by to
“on air” in a fraction of a second. Upon request, an external controller can be provided for
long range use of the device from an office or from other service points.
•
Compliance with the strictest regulations.
This device was designed in full compliance with
CCIR, FFC, and other strict international regulations, as well as the recent, strict EC anti-
magnetic noise requirements. In addition, this device complies with EC and ETSI 302.018-2 v
1.1.2.1 (2006-03) standards.
