Rear Panel Features
The rear panel provides six balanced XLR audio outputs, two 50 Ohm BNC antenna inputs, two 50 Ohm
BNC antenna outputs from an internal multicoupler, a
power jack with a locking connector, with USB and RS232 serial ports for setup and control.
Power Input Jack
The power input jack accepts +10 VDC to +18 VDC
(center pin is positive and sleeve is ground). The input
is diode protected to prevent damage if the power is accidentally applied with reversed polarity. The unit will not
operate until the correct polarity is restored.
Receiver Modules
Up to six receiver modules in two rows of three can be
installed in each VRM. Spring loaded Receiver Module
Retainer Clips ensure module connections are maintained during transport and installation.
XLR Audio Output Jacks
Six balanced XLR audio output jacks connect the
Venue System to external equipment. The default value
for receiver audio output is XLR pin 2 “in phase” with
regard to the audio signal from the transmitter. This can
be reversed for each receiver using the LCD or control
software.
Note: Audio phase is reversed by some wiring
schemes for lavalier microphones on belt pack
transmitters.

Modules 1-3
Serial Port
A serial RS-232 interface is provided for setup and
control of the Venue System from computers or other
devices using industry standard RS-232 communication
links.
Antenna Input Jacks
Two BNC input connectors are provided for right-angle
whip antennas, cables from remote antennas, or cables
from another VRM. An internal mulitcoupler ensures the
RF is applied equally to all installed Receiver Modules
and also to the Antenna Output Jacks.
Multicoupler (antenna) Output Jacks
The built-in antenna multicoupler provides RF distribution for the six receiver modules and a “loop thru” output
to deliver the RF to another Venue receiver. The second receiver can then feed a third receiver to create a
“stack” that operates with a single pair of antennas. The
result is very efficient use of rack space.
Note: Venue receivers with a 50 MHz bandwidth
must be on the same frequency blocks to use the
antenna loop through.
USB Port

Hardware Installation
Installing/Removing Receiver Modules
VRS and VRT receiver modules can be mixed in one
VRM chassis, For ratio diversity operation, both modules in the pair must be on the same frequency block
and positioned in the assembly in keeping with the
labeling on top of the chassis housing.
With the 50 MHz bandwidth version, all modules must
also be within the passband of the VRM assembly frequency blocks are marked on the housings.
Installing Receiver Modules
1. Turn the power off first.
The receiver modules interface with the main assembly through multi-pin connectors on either side
of the chassis. Insert the module straight down and
then slide it toward the main housing to insert the
connector pins. The module should sit flush against
the side of the housing.
Rack Installation
The Venue Receiver is designed for standard rack
mount installation. Each VRM chassis occupies a single
rack space.
1. Physically install the VRM(s) in the desired
location(s). There are no special ventilation requirements.
2. Connect the antennas or coaxial cables to the
antenna input connectors (outermost) on the rear
panel of the VRM.
Note: The frequency bandwidth of the antennas
must cover the range of the modules in use.
3. For multiple unit installations, connect coaxial
cables from the antenna outputs the first VRM to
the antenna inputs on the next unit in the stack.
The outermost connectors are the inputs connected
to the antennas on the first unit in the stack. The
innermost connectors are the outputs that feed the
next assembly in the rack.
Caution: Make sure the connectors align
correctly. Do not force the module onto the tab.
Excessive force may damage the connectors.
2. Align the ridge on the retaining clip with the slot in
the chassis and press the clip downward until the
ridge snaps into the slot on the chassis.
Removing Receiver Modules
1. Turn the power off first.
2. Remove the retaining clips by pressing sideways to
rotate the clip until it releases from the slot in the
metal side panel. Then pull upward to remove it.
3. Pull outward on the module to release the connector and then lift it upward out of the chassis. Holes
in the underside of the chassis allow you to grip the
module on the top and bottom.
6
4. Plug the VR power supply into a suitable outlet and
plug the power connector into the Power Input Jack.
Repeat for each Venue System being installed.
5. Turn down the audio inputs on all the externally
connected equipment, then connect them to the appropriate Audio Output XLR Jacks.
6. If the Venue System is to be set up using a computer system using a USB interface, connect a USB
cable between the USB connector on the rear panel
of the VRM and the computer system or a USB hub
connected to the computer system.
7. Refer to “Setting Up the Venue System via the USB
Port.”

Powering On and Off
When the Venue receiver is first powered up the LCD
will show the firmware revision and the tuning range
of the host assembly. The narrowband version of the
VRM covers a 50 MHz bandwidth, which includes two
adjacent frequency blocks. The firmware in the narrowband version launches a boot sequence automatically
to detect the installed modules.
The receiver will automatically start the detection sequence to identify the modules installed.
When detection is complete, the LCD will briefly display
the frequency blocks of the installed modules.
Once the initial startup is complete, go to the next
section of this manual for details on setup and
configuration options.
To power off the unit, press and hold the red power
switch for several seconds. The LCD will display a message briefly then power down.

Select Diversity Modes
Press MENU/SELECT and rotate the knob to SetUpRx
and press the knob. The SetUpRx screen provides
menu selections for various operating parameters.
Rotate the knob to DivMode and press the knob again.
Three diversity reception modes are available:
• Switched Diversity
• OptiBlendTM Ratio Diversity
• Frequency Diversity
Switched Diversity
In this mode the phase of one of the antennas is
switched when the RF signal level drops down to a
point where a dropout is about to occur. Each receiver
produces an audio output channel for a maximum of six
in each VRM assembly.
Frequency Diversity
Frequency Diversity differs from the other two diversity
modes in that it uses two receiver modules and two
transmitters operating on a different frequencies. The
purpose of frequency diversity is to have redundancy in
the system for critical productions such as live television. The receiver will pan to system with the strongest
RF signal to maintain operation during dropouts, dead
transmitter batteries, etc.
Frequency Diversity has two modes of operation: normal mode and test mode. Test mode is automatically
activated when the DivMode Setup Screen is active and
Frequency Diversity is selected. In this mode, the audio
is always blended 50/50 to allow balancing of the transmitters. The phase of one audio channel is inverted so
the two will cancel each other (null) when mixed at the
same level. On exiting the DivMode Screen, the normal
mode is activated and the blending ratio is controlled by
comparing the RF signal strengths at each receiver.
Note: In Frequency Diversity mode, both
transmitters must be the same type and model
and be operating in the same compatibility mode.
The microphones must also be placed very close
together to minimize comb filtering.
OptiBlend (Ratio Diversity)
Ratio diversity uses two adjacent receivers and pans
back and forth to blend their audio outputs to favor the
one with the strongest RF signal.
Most of the time both receivers have good signals, so
the audio is blended equally, which improves the signal
to noise ratio by 3 dB. The advantage to this mode is
that the comparator and panning take place at higher
RF levels, long before the receiver is close to a dropout.
The receiver will pan to the quieter receiver long before
the signal gets weak enough to cause a dropout. The
panning action is smooth and seamless to avoid any
audible artifacts that would occur with abrupt switching.
In this mode two paired receivers are used for a single
audio channel. The total number of audio channels will
vary according to how many modules are set to the
switching mode and how many to the ratio mode.
1. Verify that the frequency and compatibility modes of
the receiver modules match the associated transmitters and that the transmitters the same model.
2. Set up the transmitters according to the manufacturer’s recommendations and adjust the input gain
for the voice levels expected during the production.
3. Navigate to the DivMode Setup Screen.
4. Plug a set of headphones into the front panel
PHONES jack to monitor the blended output.You
can also monitor the output from the rear panel
XLR jack on either receiver in the pair.
INVT shown in Off Position
5. While listening to the blended output, adjust the
gain control on one of the transmitters so that the
audio loudness drops way down (nulls). If the output
does not null, then reset the transmitter input gain
control back to where it was and press the Function button on the front panel next to INVT on the
LCD. This will invert the phase of the audio on the
second receiver so it will null properly.

Find Clear Channels
Using Tuning Groups to Find Clear Channels
Under the SetUpRx menu, Tuning modes can be selected for manual frequency selection.
There are four pre-coordinated frequency groups, plus
two groups that can be customized for specific applications. Groups “a” though “d” are stored frequencies that
are free from IM. Groups “u” and “v” are user defined
to build custom groups. In the sequence that follows
“Group a” is used as the example.
1. Turn off all transmitters, then press the front panel
button under the receiver you wish to program.

3. Rotate the MENU/SELECT control through the preselected frequencies while observing the RF Signal
Strength meter. Select a frequency where no RF
signal is indicated on the meter.
Using Full Spectrum Scan to Find Clear Channels
In crowded RF environments, it may not be possible to
find enough clear channels using a Tuning Group. The
internal spectrum scanner can then be used to find
clear channels manually across the entire tuning range
of the receiver in 100 kHz steps. The Scan Function
automatically selects two receivers (one from each frequency block) for spectrum scanning purposes.
1. Turn off all transmitters and set all receiver modules
to the NORMAL tuning mode.
2. Press the MENU/SELECT knob and select Scan.
Press the knob again to start the scanning. The receivers used for the scan are selected automatically
and highlighted on the LCD.

Adjust Audio Output Levels
This sets the audio output level at the Audio Output
XLR Jacks. The front panel LEVEL knob is only for
adjusting the loudness at the PHONES jack.
The key is to provide as high a level signal as possible
without overdriving the input to external equipment or
driving a subsequent stage in the signal chain into limiting or compression. Ideally, the gain needed to drive
the rest of the signal chain should be present at the
receiver outputs, with each successive stage in other
equipment set to unity (no gain or loss).
NOTE: In OptiBlend (ratio diversity) and
Frequency Diversity modes, the Receiver Modules
are paired (1-2, 3-4, 5-6). Setting the audio level
output on one of the receivers in the pair, sets the
audio output to the same level on both of them.

Installing the LecNet2™ USB Driver
There are two ways to connect a Windows®-based computer system to the VRM: a USB cable or an RS-232
cable. Although the USB port offers increased speed
and convenience over standard RS-232 links, it does
require the installation of a LecNet2™ USB driver.
The LecNet2™ USB driver is not part of the standard
Windows® 2000 and XP driver libraries; therefore, connecting a computer system to the VR for the first time
differs from subsequent installations. There are a few
differences between installing the LecNet2™ USB drivers on Windows 2000 versus Windows XP systems.
USB Driver Installation (Windows XP) - First Time
When the VR is connected to a Windows XP computer
system for the very first time, the Windows® Found New
Hardware Wizard automatically opens. Use the following procedure to install the LecNet2™ USB driver using
the Wizard.
1. Place the LecNet2™ Installation Disk in the PC’s
CD-ROM drive.
4. Windows will search the CD for the driver and when
it has found it. If a dialog box opens warning you
that the driver has not passed Windows Logo Testing, click “Continue Anyway.”

5. When the driver installation is complete, the final
page of the Wizard appears. Click “Finish” to close
the Found New Hardware Wizard.
USB Driver Installation (Windows XP) Subsequent Installations
The Windows XP operating system regards all LecNet2™ devices as separate USB devices because each
has a unique serial number. Because of this, Windows
XP will want to install the USB driver every time it
encounters a LecNet2™ device whose serial number it
does not recognize. However, the process is simplified
if the LecNet2™ USB driver has already been installed
at least once before on the same computer system. Use
the following procedure if the LecNet2™ USB driver was
previously installed on the computer system.
2. Windows will discover the previously installed
driver. If a dialog box opens warning you that the
driver has not passed Windows Logo Testing, click
“Continue Anyway.”
3. When the driver installation is complete, the final
page of the Wizard appears. Click “Finish” to close
the Found New Hardware Wizard.

3. Check only CD-ROM drives then click “Next>” to
search the LecNet2™ CD for the USB driver.
4. When the driver is found, the LecNet2™ device
name will be displayed along with the location of the
driver. Click “Next>” to install the driver. (The device
found will actually say “VR” instead of the “DM1624”
that appears in this example.)
USB Driver Installation (Windows 2000) Subsequent Installations
Once the LecNet2™ USB driver is installed in a Windows® 2000 system device, and subsequent LectNet2
USB devices will invoke the Found New Hardware
Wizard which will automatically load the LecNet2™ USB
driver for the new device.

Antenna Use and Placement
The Venue System is designed for rack mounting.
Although it can be operated with two whip antennas, it
is best to use remote antennas such as the SNA600
or ALP700 for optimum reception. Position the remote
antennas at least three or four feet apart and not within
three or four feet of large metal surfaces. If this is not
possible, try to position the antennas so that they are as
far away from the metal surface as is practical. It is also
good to position them so that there is a direct “line of
sight” between the transmitter and the receiver antennas.
ceilings, etc. and a strong reflection can arrive at the
receiver’s antennas along with the direct signal. If the
direct and reflected signals are out of phase with each
other and similar in strength, a cancellation (“dropout”)
may occur. A dropout can sound like audible noise
(hiss or swishing), or in severe cases, it may result in a
complete loss of both the carrier and the sound. Moving
the transmitter even a few inches will change the sound
of the dropout, or may even eliminate it. A dropout situation also may be either better or worse as a crowd fills
or leaves the room.
In situations where the operating range is less than
about 100 feet, the antenna positioning is much less
critical. However, the length of the cabling between
antennas and the system is critical. Long cable runs
can experience serious signal loss. Lectrosonics offers
in-line RF amplifiers suitable for compensating for this
signal loss. Contact your dealer or the factory for more
information.
A wireless transmitter sends a radio signal out in all
directions. This signal will often bounce off nearby walls,
Phantom Power
Remote antennas can be placed
at a distance from the VRM to
optimize reception. To overcome
loss in long coaxial cable runs, a
Lectrosonics UFM Series inline
RF filter/amp should be positioned
at the far end of the coaxial cable,
close to the antenna.
The Venue System offers a several sophisticated diversity designs which can overcome most dropout problems. In the event, however, that you do encounter a
dropout problem, first try moving the one of the remote
antennas at least three or four feet from its current
location. This may alleviate the dropout problem at that
location. If dropouts are still a problem, try moving the
antennas to entirely different locations.
Lectrosonics transmitters radiate power very efficiently,
and the receivers are very sensitive. This reduces
dropouts to an insignificant level. If, however, you do encounter dropouts frequently, call the factory or consult
your dealer. There is probably a simple solution.
Jumper positioned to
enable DC power
With amplifier in this position, gain is applied ahead
of the loss to maximize the signal to noise ratio of the
antenna system.
Power for the UFM amplifier can be supplied by the
VRM assembly through the coaxial cable by setting
jumpers on the main PC board toward the center of the
board as shown. Disconnect power from the VRM, then
remove the top cover for access to the jumpers.
NOTE: It is best practice to enable this DC power ONLY
when a UFM remote amplifier is used. Some antennas may present a short to the power supply. While the
power supply is fused and it is unlikely that damage
would occur to the VRM, it is always best to disable the
DC when it is not in use.

Pre-coordinated Frequencies
Intermodulation interference is a problem constantly
lurking in the background, especially when working
in environments where simultaneous productions are
taking place in close proximity. In these cases, proper
frequency coordination is a must. There are basically
three methods to coordinate frequencies:
• Use the built-in frequency groups
• Scan for clear channels (See SmartTune
and Scan Function.)
• Call Lectrosonics
Frequency Compatibility Chart
Considering that multiple systems can be used in a production, coordinating frequencies to minimize interference
between these channels can be a daunting process.
The Frequency Compatibility Chart was designed to assist in minimizing intermodulation problems for multiple
channel wireless systems. It does this by identifying
™
potential intermodulation problems and listing compatible frequencies and frequency groups. This chart can
be used with all Digital Hybrid Wireless™ (400 Series)
receivers.
The chart divides the frequency blocks used in the North
American market into Set 1 and Set 2, then further divides each row into two groups of eight frequencies each.
Note: The term “Set” as used here is for
clarification only. The firmware does not make
reference to “Sets”, only “Groups.”
These frequency groups are labeled A and B and C and
D, and correspond to the factory set frequency groups
(Groups A, B, C and D) described in the Tuning Setup
Screen.
Understanding and using the Frequency Compatibility
Chart is not as difficult as it first appears. There is a pattern of compatible frequencies that becomes apparent, as
illustrated on the Frequency Compatibility Diagram on the
next page.

Multi-channel System Checkout
Interference can result from a wide variety of sources
including TV station signals, other wireless equipment
in use nearby, or from intermodulation within a multichannel wireless system itself. Regardless of how the
frequencies were coordinated, a final checkout procedure is always a good idea.
The pre-coordinated frequencies on the chart on the
previous pages address in-system intermodulation,
but obviously do not take into account RF signals from
external sources that may be present in the location
where the system will be operating. The procedure outlined below is necessary to check for interference from
external sources.
Scanning with the RF spectrum analyzer built into the
Venue system will identify external RF signals, but
it does not address the compatibility of the selected
frequencies. After scanning and finding the needed
number of clear channels, the following procedure is
necessary to check the compatibility.
1. Set up the system for testing. Place antennas in
the position they will be used and connect to the
receivers. Place transmitters about 3 to 5 feet apart,
about 25 to 30 feet from the receiver antennas. If
possible, have all other equipment on the set, stage
or location turned on as well, especially any mixing
or recording equipment that will be used with the
wireless system.
IMPORTANT: Any time a frequency is changed on
any of the systems in use, you must start at the
beginning and go through this procedure again for
all systems. With a little practice, you will be able
to do this quickly and save yourself some “multichannel grief.”
2. Set all receivers on clear channels.
Turn on all receivers, but leave the transmitters off.
Look at the RF level display on each receiver. If
an indication is present, change the frequency to
a clear channel where no signal is indicated. If a
completely clear channel cannot be found, set it for
the lowest RF level indication. Once all receivers on
on clear channels, go to step 2.
3. Turn each transmitter on one at a time. Leave
the other transmitters turned off. Then, as you turn
on each one, look at the matching receiver to verify
a strong RF signal is received. Then, look at the
other receivers and see if one of them is also picking up the signal. Only the matching receiver should
indicate a signal. Change frequencies on either
system slightly until it will pass this test, then check
again to see that all receivers are still on clear
channels as in Step 2.
4. Turn each transmitter off one at a time. With all
transmitters and receivers turned on, turn each
transmitter off one at a time and look at the RF level
indicator on the matching receiver. It should “fall
silent” and the RF level should disappear or drop to
a very low level. If it does not, change frequency on
that receiver and transmitter and try it again.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment
needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting
cables and then go through the TROUBLESHOOTING section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection,
send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set at the
factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are
no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest
flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does
to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone
for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by letter or by phone. We need to
know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed
your repair through our receiving and repair departments. The return authorization number must be clearly shown
on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed” for
safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
