MS3000 UHF Diversity Wireless System Features

•Well-designed companding and audio circuitry deliver “hard-wired” sound quality

•Excellent 104 dB signal-to-noise ratio

•Metal chassis ½-rack space receiver with TNC antenna connectors

•Metering for audio level, rf and diversity channel

BNC connectors and are located on the rear panel of the MR3000. TNC connectors are widely used on cellular communications equipment and are readily available.

Two antennas are supplied with the unit for normal use and optional accessory kits can be used to rack mount or remote-mount the antennas. Other accessories such as multi-couplers, ½-wave antennas and log periodic directional antennas are also available to meet specific installation and use requirements.

•Externally-adjustable squelch control

•Balanced 3-pin XLR-type and unbalanced ¼-inch audio outputs

•Choice of transmitters including rugged bodypack with TA4F connector for lavalier and headset micro- phones. Professional handheld transmitters with choice of Electro-Voice N/D767 dynamic or BK-1 condenser transducers.

DESCRIPTION

The Electro-Voice MS3000 is a professional quality UHF diversity wireless system that operates within the frequency range of 690 to 725 MHz (TV chan- nels 50 – 55) on single custom-tuned frequencies. MS3000 Systems combine the MR3000 receiver with a choice of handheld and bodypack transmit- ters that allow multiple ways to achieve wireless freedom. The wide range of frequencies permit use of multiple systems simultaneously (the exact num- ber is dependent on local conditions). The specially designed compander circuitry provides wide dy- namic range with clean, accurate transient re- sponse. MR3000 receivers have ½-rack space metal chassis for ruggedness and reliability. A host of accessories are available for operational and installation flexibility.

SECURE-PHASEtmDIVERSITY

The MR3000 receiver utilizes patented Secure- Phasetm diversity circuitry that ensures the stron- gest, cleanest signal possible. Unlike other diversity schemes that switch antennas or signal, Secure- Phasetm utilizes the signal from both antennas at all times to increase signal strength, minimize dropouts and lower the potential for interference.

If the signal from the transmitter changes phase or polarity (a common cause of dropouts), the circuit adjusts the phase angle between the two antennas receiving circuits to prevent cancellation. The two diversity lights on the front panel indicate the status of this circuit.

ANTENNAS

The MR3000’s ½-rack space receiver has specially tuned quarter-wave antennas with TNC-type an- tenna connectors. These connectors are electrically and mechanically superior to the commonly used

HANDHELD TRANSMITTER

•Choice of Electro-Voice N/D767 (MSHD) N/DYM dynamic or Electro-Voice BK-1 condenser (MSHC) transducers.

•Special “soft-touch” finish and ergonomically designed handle makes holding comfortable and secure.

•Separate LEDs for power on and battery status for easy monitoring of operational modes.

•Separate power and audio mute switches for operational flexibility.

•Wide-range gain control allows approximately 40 dB of adjustment.

•Up to 10 hours of operation on a 9-volt alkaline battery.

BODYPACK TRANSMITTER

•UHF bodypack with TA4F connector allows the user the freedom of microphone selection with easy interchangeability. Available microphones include the Electro-Voice ULM20 cardioid con- denser lavalier microphone and the HM2 headset microphone. The TA4F connector allows connec- tion of any dynamic or condenser microphone that can be biased with 5 volts DC phantom.

•Separate on/off and toggle mute switches for operational flexibility

•LED battery condition indicator gives quick indication of battery strength

•Up to 10 hours of operation on a 9-volt alkaline battery

MR3000 FRONT PANEL FEATURES DISPLAYS

The MR3000 has a number of front panel indicators to make setup and operation easier.

1.A five-segment LED meter shows audio level and is useful for setting the transmitter’s gain control.

2.A five-segment LED RF meter shows the strength of the incoming signal from the transmitter

3.Two LEDs indicate the action of the Secure- Phasetm diversity circuitry.
