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 channels 50 – 55) on single custom-tuned frequencies.
MS3000 Systems combine the MR3000 receiver
with a choice of handheld and bodypack transmitters that allow multiple ways to achieve wireless
freedom. The wide range of frequencies permit use
of multiple systems simultaneously (the exact number is dependent on local conditions). The specially
designed compander circuitry provides wide dynamic range with clean, accurate transient response. MR3000 receivers have ½-rack space
metal chassis for ruggedness and reliability. A
host of accessories are available for operational
and installation flexibility.
SECURE-PHASEtm DIVERSITY
The MR3000 receiver utilizes patented SecurePhasetm diversity circuitry that ensures the strongest, cleanest signal possible. Unlike other diversity
schemes that switch antennas or signal, SecurePhasetm 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 antenna connectors. These connectors are electrically
and mechanically superior to the commonly used
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.
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 condenser lavalier microphone and the HM2 headset
microphone. The TA4F connector allows connection 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 SecurePhasetm diversity circuitry.

POWER SWITCH
The front-panel power switch allows the receiver to
be switched on and off easily.
SQUELCH ADJUSTMENT
The range of the externally adjustable squelch
control allows you the choice of maximizing range
or lowering the potential for external interference.
5. Open the battery compartment door on the
handheld transmitter or the bodypack and install
a 9-volt alkaline battery (see Figures 3 and 4).
8.4 volt Ni-Cad batteries may be used but will
yield noticeably shorter operational time and
slightly lower performance.
Figure 2
REAR PANEL FEATURES
AUDIO OUTPUTS
The MR3000 has both 3-pin XLR-type balanced and
¼-inch unbalanced phone jack output connectors.
The line level output is adjustable with a small
screwdriver (included).
ANTENNA CONNECTORS
The antenna inputs utilize TNC connectors that provide solid mechanical and electrical connections.
POWER INPUT
The MR3000 will operate from the supplied ac adapter
or any other battery, filtered supply or power pack that
can deliver 12 – 15 volts AC/DC, 300 mA.
Figure 3
SYSTEM SET-UP AND OPERATION
To prepare the MS3000 System for operation, you
should:
1. Connect the power supply adapter to an AC
outlet that will supply 105 to 125 volts AC, 60
Hz. Other power supply adapters are available
for 210 – 240 volt, 50 – 60 Hz operation. Make
sure that you have the correct power supply for
your locality.
2. Connect the MR3000 to your audio system using the appropriate connector on the rear panel.
It is preferable to use the 3-pin XLR connector
since its balanced circuitry minimizes the potential for electrical interference and can be used
with long cable runs.
3. Switch on the receiver with the front-panel
power switch.
4. Attach either the supplied ¼-wave antennas or
two externally mounted antennas to the antenna
connectors on the rear panel of the MR3000.
Be sure and tighten the connectors securely. If
the supplied ¼-wave antennas are used, they
must be oriented at a 90o angle as shown in
Figure 1. Unlike other diversity wireless systems, two antennas are needed for the
MS3000 to operate correctly.

6. When the battery is installed, you may plug in the
microphone to the bodypack or simply switch on
the handheld transmitter and begin operation.
7. When the system is first operated, the gain of the
transmitter should be adjusted to the vocalist or
speaker who will be using it.
• Speak or sing as loudly as possible into the microphone.
• Observe the audio level meter on the receiver.

2. Align the correct rack ear or bracket with the holes
on the side of the unit. Install the previously
removed screws. Insert an additional screw (provided in the parts pack) into the remaining hole.
Repeat this step for the opposite side of the unit.
Be sure to tighten all screws securely.
For double mounting of two systems, proceed as
follows:

• Adjust the gain control on the transmitter (see
Figures 2 and 4) to prevent over or under-modulation. The gain should be adjusted so that the signal
peaks are no more than +0 dB and that there is at
least –10 dB of audio level meter indication.
8. The squelch control on the front of the receiver
may be adjusted to increase range or reduce
interference. If the squelch control is being adjusted, it should be adjusted with the transmitter
off. CAUTION—DECREASING SQUELCH WILL
MAKE THE SYSTEM MORE SUSCEPTIBLE
TO OUTSIDE INTERFERENCE! Use the small
screwdriver supplied with the unit and turn the
squelch control clockwise to reduce interference
from noise and spurious radio signals. To best set
the squelch control, turn the control counter-clockwise until you hear noise and interference and then
turn it back clockwise until the noise is squelched
off. This setting will give you the best balance
between noise and reduced range.
9. Before using the system before an audience, it is
a good idea to “walk” the expected use area to
check for dropouts. To minimize the potential for
dropouts, please observe good antenna placement. When the transmitter is turned on, the RF
meter on the receiver should be illuminated in the
green range to verify it is receiving a strong signal.
10. When the transmitter power switch is turned on,
the red battery light will flash one time if the battery is good and has adequate strength. If the
red light does not flash or stays on continuously,
the battery is weak and should be replaced.
1. Align the mid-sized brackets (item #2) with the
holes on the adjacent sides of each unit.
2. Install the previously removed screws. Insert an
additional screw (provided in the parts pack) into
the remaining holes. Tighten all screws securely.
Figure 6
3. Place the two assemblies side-by-side with the
mid brackets together. (The left bracket should
fit above the right so that the countersinks are
visible). Install 4 flat-head screws (item #5) and
tighten them securely.
4. Attach the antenna connectors to the brackets.
5. Attach the supplied extension cables from the
rack connectors to the antenna connections on
the back of the receiver.
4. Place the assembly in to the 19-inch rack enclosure and insert 4 #10-32 x 3/8” Phillips pan
head screws (supplied) in each corner of the
rack ears and secure to the enclosure.
Figure 7
RACK-MOUNT INSTALLATION
The MR3000 is supplied with rack mounts for single
and double mounting in a standard EIA 19” equipment rack (see Figure 6). For rack mounting a
single unit, a long and short “ear” are used. For dual
side-by-side mounting, use the short “ears” and the
mid sized brackets from two MR3000s as shown.

MS3000 OWNERS MANUAL
ANTENNA PLACEMENT
For any wireless system to perform correctly, strong
RF signals are mandatory. To maximize signal
strength, good antenna placement must be utilized.
Although some situations prohibit perfect antenna
placement, here are some guidelines:
and can provide an additional 5 dB of gain
3. If you remote-mount the antennas, attention
should be paid to the type and quality of the
antenna cable. For cable runs longer than 25-ft
(7.6 M), special low-loss cables should be used.
Figure 10
1. The antennas should be placed in a location
with a clear signal path to the transmitter. Walls,
ceilings, metal objects, equipment racks, etc.
are all signal barriers that will reduce range and
performance. Generally speaking, placing the
receiver at an elevated location can help increase range and signal strength.
2. If the receiver is rack-mounted, external antennas are necessary. Do not rack mount
the MR3000 with the antennas mounted
directly on the back of the unit. This will
severely decrease the range and performance of the system.
If the MR3000 is rack-mounted, make sure the
antennas are front-mounted (following the directions noted above). If antennas are mounted
remotely from the chassis, the ¼-wave antennas supplied with the receiver cannot be used.
The ½-wave antennas are a necessity if the antennas are remote-mounted and can provide
better performance when used with the rack
mount.
Figure 8—½-Wave Antenna for Remote Mounting
Figure 11
Figure 9
If antennas are remote-mounted, separating
them 6 feet (1.8 M) or more and keeping them
at least 2 feet (.6M) from other barriers will improve performance (see Figure 11). If you are
remote mounting the antennas and require
strong signal over a large area, consider using
highly directional antennas such as a log-periodic. The LPA500 available from Electro-Voice
is tuned for frequencies from 450 – 900 MHz
page 6
MS3000 OWNERS MANUAL
Figure 12
These cables are available as accessories (see
accessories listing).
4. If multiple wireless systems are being used, a
multi-coupler will minimize antenna interference.
A multi-coupler has one set of antennas and
distributes RF signal to multiple systems. The
Electro-Voice A/P4X4 will supply antenna signal
and DC power to 4 systems, eliminating 3 external power supplies and 6 antennas (Figure 12).
COMPATIBILITY
The receiver and transmitter must be tuned to the
same frequency in order to operate together as a
system. Mixing brands of wireless components,
even if units have the same frequency, will not work
due to differences in companding circuits.
If two or more MS3000 and/or other VHF/UHF wireless systems are being used in the same location,
proper frequency coordination is necessary to avoid
interference. Frequency mixing and spacing must
be factored along with local TV stations to determine if conflicts will result from a specific group.
Contact your dealer or Electro-Voice for frequencyselection assistance if you are planning to add more
wireless systems to be operated simultaneously in
the same location.
POTENTIAL SOURCES OF INTERFERENCE
There are many potential sources of interference for
your wireless system. Any electronic component
that contains digital circuitry including digital signal
processors (reverb/multi-effects units), electronic
keyboards, digital lighting controllers, CD players
and computers all emit rf energy that can adversely
affect the performance of your wireless system. It is
always best to place your receiver as far away from
these devices as possible to minimize this potential
source of interference.
