MRC DRS4000, User And Technical Manual

Page: 13 / 88

Introduction 1-5 DRS4000 Receiver User and Technical Manual
1.8 Hardware Components
A typical installation consists of a receiver, antennas, low-noise
block downconverters, and cables.
1.8.1 Receiver
The DRS4000 Receiver accepts 2 or 4 antenna inputs and
incorporates MaxRC diversity technology, COFDM
demodulation, SD/HD MPEG decoding, and DVB-T and LMS-T
demodulation modes. With a front panel video monitor and
control screen, the receiver takes up only 2 RU of space in a 19-
inch rack. The receiver can be operated locally or remotely via a
master controller.
Base models include:
• DRS4000 4-input receiver with MaxRC, SD, and LMS-T
(DRS-R4LAJ)
• DRS4000 4-input receiver with MaxRC, SD, LMS-T, and
ASI Packet Switch (DRS-R4LAJP).
1.8.2 Antennas
MRC offers several types of antennas and several models within
some antenna types.
See ”Antenna Options” on page 1-7 for
more information.
1.8.3 Low Noise Block Downconverters
The DRS4000 Receiver is compatible with several MRC and
Link Research downconverters (LNBs). The downconverters
transform the incoming RF signal into UHF for input to the
receiver.
See ”Block Downconverter Options” on page 1-6 for
additional information.
1.9 Firmware Components
The DRS4000 Receiver is controlled by software installed on
programmable read-only memory (PROM). You can access this
firmware via the front control screen, and use it to monitor the
incoming signal and control settings such as channel and
frequency.
The firmware also provides a web browser interface that you can
access via a web browser on any PC or laptop computer as long
as both the DRS4000 Receiver and the computer are connected
to the same Local Area Network (LAN). You can also access the
web browser interface via a direct Ethernet connection.
See
”Routine Operation” on page 2-1 for additional information.
1.10 Frequency Bands
The DRS4000 Receiver can operate in one of several factory-
programmed frequency bands. You can select the band via the
front control screen or via a master controller interface at the
studio or command center.
MRC offers a range of block downconverters and antennas
designed for each frequency range. The downconverters
transform the incoming RF signal to a 110 to 860 MHz VHF/UHF
signal while the DRS4000 Receiver is capable of accepting a
signal in the range of 70 to 860 MHz.
The following frequency bands are supported:
• 2 GHz
• 3 GHz (non-U.S.)
• 5 GHz
• 7 GHz
• 1.9 to 2.5 GHz / 6.4 to 7.1 GHz (dual band support option)
