SR 4000

Description

a) Hardware

The SR 4000 UHF receiver is one standard EIA rack unit high and one-half rack unit

wide with a full metal chassis. Thus, two receivers can be placed side-by-side in one

rack space (rack-mount hardware included). The SR 4000 has a 30 MHz wide UHF

band containing presets with intermodulation-free frequencies as well as a tuning

mode with access to up to 1,200 switchable frequencies. The SR 4000 utilizes

operates as a true diversity receiver, in which two completely separate antenna,

receiver and demodulator sections are operational at all times. The receiver includes

a Pilot Tone Decoder Unit that decodes transmitter data out of the Pilot Tone's data

stream. This enables the SR 4000 to show battery charge status and mute status of

the transmitter on the integrated, back-lit color display. This data is also available at

the Logic Output Connector on the rear panel. The HT4000 & PT4000´s Pilot Tone

allows automatic muting of the SR´s audio output in case of invalid or corrupted

signal (Tone Code Squelch TCSQ). If necessary this automatic squelch option can be

overruled by a manual squelch setting. For PC control and monitoring of the SR unit

a special data port is available on the rear panel of the SR 4000.

The True Diversity receiver concept offers maximum dynamic range, greater freedom

from interference and noiseless switching from one receiver to the other. Both balanced

3-pin XLR and unbalanced 1/4-inch output connectors are available. An output level

switch allows the adjustment of 3 output levels (-30, 0, +6 dB) for optimum system

gain structure. Also available on the rear panel are a data port connector, a logic

output, 2 x BNC antenna Connectors and a lockable DC input jack.

Controls on the SR 4000 include a backlit display and a Jog wheel to adjust various

receiver settings such as squelch threshold, carrier frequency selection, user's name,

scan & rehearsal mode selection and many more. Indicators on the unit include mute,

audio level bargraph, RF level bargraph, 6x14 segment alphanumeric display and

menu control. A unique, programmable Status Control Ring shows the most important

system data at one glance.

Each SR 4000 can accommodate a pair of diversity antennas; however, when a

number of receivers are used in a single system, a master antenna pair (with or

without antenna booster, directional and omnidirectional antennas) can be used to

feed all receivers. A wide range of accessories such as an antenna splitter, antenna

combiner and antenna booster are provided for operational flexibility and

ease of installation.

b) Software

The internal software of the SR 4000 offers a

wide range of control features for an easy setup

even in complex multi-channel systems under

difficult rf conditions. Most helpful are features

like AutoSetup (automatic intermodulation free

channel selection), EnvironmentScan (scanning

of the unit's RF range), and RehearsalMode

(recording of important system data during

rehearsal helps optimize the system setup). Important settings

like frequency, squelch, unit name, etc. can be edited and stored via

an easy menu structure. Even more control & monitoring features are available

via the optional MCS 4000 (MissionControl Software) PC Control Software.
