Introduction
The Venue is a modular rack mount receiver for use
with a wide variety of transmitters from Lectrosonics
and other manufacturers. Designed for maximum versatility and performance, the Venue receiver offers unprecedented flexibility for reliable operation, even in today’s
increasingly congested RF environments.
A Venue receiver is a “system” that consists of a master
unit and up to six receiver modules. Two different types
of receiver modules are available. The standard module
(VRS) is an excellent choice for fixed installations where
fairly clear RF spectrum is available. The tracking module (VRT) is a more costly alternative, but its tracking
front-end makes it the better choice for use in congested RF environments. VRpanel software is included to
simplify setup and monitoring.
This guide covers the essential steps and settings
needed to get a Venue system up and running. It covers
the hardware installation, configuration using the LCD
on the master unit, setting up a USB port on the computer and installing the VRpanel software.
LecNet2 software runs under Microsoft Windows
XP and VistaTM operating systems.* An online Help in
the software includes a listing of commands used to
control the Venue through the serial ports.

(labeled by the LCD)
POWER Switch BACK Button
The Venue receiver master unit (VRM) serves as a
“host assembly” for up to six receiver modules. The
standard module (VRS) and tracking module (VRT) can
be mixed and matched in the assembly in any combination to suit the needs of various applications.
The VRM front panel provides an LCD for system setup,
monitoring and troubleshooting. During normal operation, the LCD shows RF and audio levels, diversity
status, pilot tone status (where applicable) and transmitter battery status (in certain modes) for all six receivers
at the same time. Individual screens for each receiver
provide additional information and adjustments.
A built-in analyzer scans the tunable spectrum of the
receiver to assist in finding clear operating frequencies.
The spectrum scan data is presented in a graphical
format on the LCD.

Power Input
Multicoupler Outputs
The rear panel provides six balanced XLR audio outputs, antenna inputs, “loop thru” antenna outputs from
an internal multicoupler, a power jack with a locking
connector, plus USB and RS-232 serial ports for setup
and control.
Receiver Modules
Up to six receiver modules can be installed in each
Venue receiver rack mount chassis. Spring tensioned
clips retain the receiver modules to maintain secure
connections with the host assembly.
XLR Audio Output Jacks
Six balanced XLR audio output jacks connect the Venue
receiver to external equipment. By default, pin 2 is audio pos (+). The polarity of each output can be reversed
in the LCD setup menus or with the software.
Power Input Jack
The receiver is powered from +10 VDC to +18 VDC,
with the center pin of the connector positive (+). The
input is diode protected to prevent damage if the power
is accidentally applied with reversed polarity.
RS-232 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 Inputs
Antenna Input Jacks
The two outermost BNC connectors are provided for
use with right-angle whip antennas, cables from remote
antennas, or cables from another Venue receiver. DC
voltage can be supplied on these connectors from an
internal source to power remote RF amplifiers. The
power is enabled with jumpers on the circuit board. See
the section on Antenna Use and Placement for details.
Multicoupler Output Jacks
The built-in antenna multicoupler provides RF distribution for the six receiver modules and a “loop thru” output
at the same level to deliver the RF signal to another
Venue receiver. The second receiver can then feed a
third receiver and so on, to create a “stack” that operates with a single pair of antennas. The result is very
efficient use of rack space and a cost savings by not
having to purchase a separate antenna multicoupler.
USB Port
Standard USB Version 1.1 port for setup and control of
the receiver from computer systems using Windows
2000, XP or VistaTM operating systems.

Hardware Installation
Receiver Modules
VRS and VRT receiver modules can be mixed in the
same 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
OPTI-BLEND labeling on top of the chassis housing.
All modules must be within the frequency passband of
the host assembly. Frequency blocks are marked on the
receiver module and chassis housings.
Installing Receiver Modules
1. Turn the power off.
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
1. Mount the receiver(s) in the desired rack 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.
Note: The frequency bandwidth of the antennas
must cover the range of the modules in use.
3. For multiple unit installations, a “loop thru” is available to feed two or three receivers from a single
antenna pair. Connect coaxial cables from the multicoupler outputs on the first receiver to the antenna
inputs on the next receiver 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.
Retaining
clips
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 in the side panel.
Removing Receiver Modules
1. Turn the power off.
2. Remove the retaining clip by pressing on it side-
ways to release it from the slot in the 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.
8
4. Plug the power supply into a suitable outlet and
plug the power connector into the Power Input Jack.
5. Turn down the audio inputs on all the externally
connected equipment, then connect cables to the
appropriate Audio Output XLR Jacks.

LECTROSONICS, INC.
Digital Hybrid Wireless™ Modular Receiver System
Three diversity reception modes are available:
• Switched Diversity uses one receiver module per
audio channel.
• Ratio Diversity (OptiBlend
TM
) uses two receiver
modules per audio channel.
• Frequency Diversity uses two receiver modules
and two transmitters per audio channel.
Press the Receiver Select Buttons to enter the setup
screens for the receiver modules.
Switched Diversity
In this mode the signals from both antennas are combined into a single receiver module, with the phase of
one of them inverted back and forth so that they always
add to one another. The process reduces dropouts and
provides a stronger signal than a single antenna.
Ratio Diversity (OptiBlendTM)
Frequency Diversity
Frequency Diversity differs from the other two diversity
modes in that it uses two receiver modules and two
transmitters operating on different frequencies. The purpose of this mode is to have redundancy in the system
for critical productions, such as live television, to guard
against failures caused by dead batteries and multipath
dropouts. The blending process to combine the audio
from the receiver modules is the same as that used for
OptiBlend ratio diversity.
Frequency Diversity requires that the levels of the two
audio channels to be closely matched to avoid audible level changes as the blending action takes place.
In order for this blending to work properly, a special
test mode helps to get the transmitter levels exactly
matched. The test mode is automatically activated when
the DivMode Setup Screen is active and Frequency
Diversity is selected, as shown in the LCD photo above.
Note: In Frequency Diversity mode, both
transmitters must be the same type (usually the
same model). The microphones must also be
placed very close together to minimize comb
filtering.
Ratio diversity uses two adjacent receiver modules to
pick up a single transmitter. The audio outputs of the
modules are blended (mixed) together, using more or
less audio from each module based upon which module
has the stronger RF signal.
Ratio diversity anticipates dropouts before they occur,
rather than waiting until the RF signal level is very weak
and on the verge of noise or dropout. The comparison
of the RF signal levels in the modules begins when the
RF level is still high, so the circuit can blend in more
audio from the module with the stronger signal before
the signal decays enough to cause noise.
The blending action is smooth and seamless to avoid
any audible artifacts that can occur with abrupt switching. Most of the time both receiver modules have good
signals, so the audio is blended equally, which improves
the signal to noise ratio by 3 dB.
The blended audio appears at the rear panel XLR outputs of both modules.
To prepare for operation in the Frequency Diversity
mode, make the following adjustments:
1. Set up the transmitters according to their instructions. 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 for either module in the pair.
2. While listening to the blended output, adjust the
gain control on one of the transmitters so that the
audio loudness drops way down (nulls) as the two
channels cancel each other. 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 the word INVT on the
LCD. This will invert the phase of the audio on the
second module so it will null properly.
INVT shown in Off Position
Rio Rancho, NM, USA
13
Venue Narrowband Receiver
Depending on how microphones are wired and
other vagaries, either position of the INVT toggle
switch might achieve the null. Keep toggling the
switch until the null is found, adjust the level for the
deepest null, then press INVT one more time to put
the transmitter audio back in phase.
3. Repeat Steps 1 and 2 for each receiver module pair
set to Frequency Diversity Mode.
Finding Clear Channels with SmartTune
SmartTune simplifies setup by scanning the tuning
range of the receiver and automatically setting a receiver module to a clear frequency. A receiver module
is selected, a scan is completed and the frequency is
set for that module. A prompt appears, reminding you to
turn on a transmitter on the newly selected frequency,
and the procedure continues until all modules have
been tuned to clear frequencies.
NOTE: SmartTune is only available using the LCD
and front panel controls. It is not implemented in
the VRpanel software.
1. Navigate to the SmrtTun setup screen.
When the transmitter is turned on and detected, the
display will return to receiver selection (Step 2) and
prompt you to select the next receiver.
5. Repeat steps 2 through 4 for all receiver modules
that will be used.
6. Press the Back button several times to return to the
overview screen.
7. Conduct a system checkout with the procedure
explained in the section entitled Diagnostics.
2. Press the Receiver Select Button for the module
you wish to tune and scanning will begin.
When the full spectrum has been scanned, the cursor will stop moving and blink briefly on the newly
selected frequency.
3. The display will then switch back to the receiver selection screen and ask if you want to tune another
module.
4. If you select Yes the display will remind you to turn
on the transmitter for the receiver you just tuned.

Finding Clear Channels with Tuning Groups
Tuning Groups include two groups (“u” and “v”) that can
be customized for specific applications and four precoordinated frequency groups (“a” through “d”) that are
free from intermodulation.
Digital Hybrid Wireless™ Modular Receiver System
The scanning begins automatically. Allow the scanner to continue sweeping through the tuning range
several times, then press the Function button to
enter “Stop Mode.”
Groups “u” and “v” are blank by default. Each group can
store up to 16 user defined frequencies to build custom
groups, however, the stored frequencies must be tested
to determine their compatibility.
Groups “a” though “d” contain 8 frequencies each that
can be used together in certain combinations. In brief,
“a” and “b” are compatible with each other and “c” and
“d” are compatible with each other. Other combinations

Venue Narrowband Receiver
Adjusting Audio Output Levels
The audio output levels at the rear panel XLR jacks are
software controlled. (The front panel LEVEL knob affects the PHONES output only.)
The optimum output level will provide the highest level
signal possible without overloading 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 Ratio Diversity and Frequency Diversity
modes, the receiver modules are paired 1-2, 3-4,
5-6. Setting the audio level output on either module
in the pair, sets the audio output to the same level
on both of them.
1. Navigate to the Level setup screen.
The highest level that the equipment downstream will
ever see before the receiver clips is 4.5 dB higher than
the test tone. Note that this is output headroom. Over
the entire 30+ dB range of the limiter in a Lectrosonics
transmitter, the output at the receiver goes up only 4.5
dB or less.
NOTE: The tone is a sine wave with about 1%
distortion
Selecting Audio Phase
Microphone wiring and other vagaries can alter the
phase of an audio signal. To compensate for this, the
phase of the audio output of each receiver module can
be inverted.
1. Navigate to the Phase setup screen.
2. Select each receiver one at a time with the buttons
under the LCD and rotate the knob to adjust the
output to the desired level.

The indicator will reverse to a dark background
with light letters when the tone is delivered to the
selected output. Rotate the MENU/SELECT control
to set the desired level.
WARNING: The 1 kHz reference tone is
equivalent to full modulation at the transmitter.
It is LOUD.
The test tone level is always at the 0dB reference level
(full modulation of the wireless system), which is the
level at which the first red “limit” light comes on at the
transmitter.
2. Select each receiver module with the Receiver
Select Button and adjust the phase with the MENU/
SELECT control.
Selecting Transmitter Battery Status
Monitoring Mode
The receiver will monitor the status of the batteries in
the transmitters and display it when used with certain
transmitters, such as Lectrosonics 200 Series and Digital Hybrid models. The type of battery being used in the
transmitter must be defined in the TxBatt setup screen.
NOTE: The Compat Mode (compatibility mode)
set for each receiver module will determine which
battery monitoring methods are available
The TxBatt setup screen allows you to select the exact
battery being used in the transmitter to provide more
accurate battery level monitoring. Alkaline, lithium and
rechargeable AA and 9V types are commonly used.
The voltage declines gradually over the life of alkaline
and lithium types, so the voltage can be estimated and
displayed by the receiver. Rechargeable types, on the
other hand, maintain almost constant voltage as they
discharge, so a timer is provided in the receiver to
track operating time and anticipate the need for battery
changes.

LecNet2™ software and the VRpanel for the Venue
Receiver.
Installing the LecNet2™ USB Driver
A Venue receiver can be connected to a computer with
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 Venue receiver 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 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.”

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
ALP Series 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.
In situations where the operating range is less than
about 100 feet, the antenna positioning is much less
critical. The length and type of cabling between antennas and the system, however, 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,
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 or “dropout” may occur. A dropout can sound like audible noise
(hiss, swishing or a “shhht” sound), or in severe cases,
may result in a complete loss of both the carrier and the
sound. Moving the transmitter even a few inches can
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.
The Venue System offers several different diversity
reception methods which can overcome most dropout
problems. In the event, however, that you do encounter
a dropout problem, first try moving one of the remote
antennas at least three or four feet from its current
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, which 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.
Powering Remote RF Amplifiers
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 lter/amp should be positioned
at the far end of the coaxial cable,
close to the antenna.
With the 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
Venue receiver through the coaxial cable by setting
jumpers on the main PC board toward the center of the
board as shown. Disconnect power and then remove
the top cover for access to the jumpers.
Jumper positioned to
enable DC power
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, it is always best to disable the DC when it
is not in use.

Pre-coordinated Frequencies
Interference from IM (intermodulation) is a potential
problem in all multi-channel wireless systems, so proper
frequency coordination is always required to avoid
noise, range and dropout problems. Your options to accomplish this include:
• Using the pre-coordinated frequency groups
• Performing a system checkout
(See Multi-channel System Checkout)
• Calling Lectrosonics for assistance
Compatible Frequency Table
Groupings of compatible frequencies have been created to minimize intermodulation problems in multiple
channel wireless systems. The frequencies can be used
with Digital Hybrid and analog Lectrosonics wireless
equipment. Compatibility with other brands is likely, but
not guaranteed by Lectrosonics.
The table provides two different sets of pre-coordinated
frequencies for frequency blocks 21 through 29. The
table is constructed to create a visual pattern of compatible frequencies to make it easier to use. The frequencies are stored in memory in various products and
included in the VRpanel software.
Pre-coordinated frequencies are arranged
in four groups as shown
at right.
The uppermost eight
frequencies comprise
Grp a, the eight just
below them comprise
Grp b, and so on.

Compatibility follows the pattern illustrated in the diagram at right.
Grp a and Grp b contain the 16 frequencies shown in
the table below (upper orange/white set).
Grp c and Grp d contain the 16 frequencies shown in
the table below (lower blue/white set).
NOTE: There is no assurance that frequencies
are compatible between the upper orange/white
set and the lower blue/white set. Combined use of
frequencies from both sets requires testing with
the procedures outlined in the following section
entitled Diagnostics - Multi-channel System
Checkout
These frequencies share RF spectrum with TV chan-
nels. The upper orange/white set and the lower blue/
white set of frequencies provide two different lists of TV
channels. Use the set with fewer active TV stations in
the area where you are operating.
Active TV station signals can be discovered by scanning
with the Venue receiver, or researched in advance on
this web site: www.fccinfo.com.

Venue Narrowband Receiver
Diagnostics
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.
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.
The pre-coordinated frequencies on the chart on the
previous pages address in-system intermodulation,
but obviously cannot take into account RF signals from
external sources that may be present in the location
where the system will be operating.
In some cases, you can run the scanner to find clear TV
channels, then find enough pre-coordinated frequencies
in the tuning groups (Grp a through Grp d) to operate
on the clear TV channels. Even so, it is still a good idea
to go through the check out procedure because you
can encounter interference from other wireless, IFB and
intercom systems when you get to the production or
installation site.
1. Set up the system for testing.
Place antennas in the position in which 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.
2. Set all receivers on clear channels.
Turn on all receivers, but leave the transmitters off.
Observe at the RF signal strength indicator for each
receiver module. If a signal is present, change the
frequency to a clear channel where no signal is
indicated. If a completely clear channel cannot be
found, select the frequency with the lowest RF level
indication. Once all receiver modules are on clear
channels, go to step 3.
4. Turn each transmitter off one at a time.
With all transmitters and receivers turned on, turn
each transmitter off one at a time, in turn, and look
at the RF level indicator on the matching receiver
module. 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. When
a clear frequency is found, turn the transmitter on
and move on to the next channel.
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.”
Pilot Tone Bypass
Some wireless equipment uses a supersonic “pilot tone”
to control the squelch (audio mute) of a receiver module
to keep it silent until a valid signal is received. When a
signal with the correct pilot tone is received, the squelch
opens and audio is delivered to the output. Pilot tone
squelch control also eliminates transients (clicks and
pops) when transmitters are turned on and off. Pilot
tone is supported in the Digital Hybrid compatibility
modes for those systems that use it.
Pilot tone control can be bypassed as a diagnostic tool.
Bypass opens the audio output of the receiver unconditionally, allowing you to listen to any signals entering the
receiver to help identify their source. Pilot tone bypass
will also allow you to use a transmitter that has a defective pilot tone circuit.
CAUTION: When pilot tone is bypassed and
the transmitter is turned off, excessive noise
will be present. Turn the audio level down
before bypassing pilot tone.
Navigate to the PilotBP setup screen.
3. Turn each transmitter on one at a time.
Start with all transmitters turned off. 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 all channels pass this test, then check
again to see that all channels are still clear as done
in step 2.
28
Select the receiver module with the Receiver Select
Button and rotate the MENU/SELECT control to select
BYPASS. In this example, the pilot tone for receiver
module 1 is set to BYPASS (BYP) and the others are
set to NORMAL (NOR).

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.
