Introduction
The Venue Wideband receiver is a modular rack mount
design for use with a wide variety of transmitters from
Lectrosonics and other manufacturers. Designed for
maximum versatility and performance, the wideband
design offers the flexibility needed in today’s changing
and 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 mod-
ule (VRT) is a more costly alternative, but its tracking
front-end makes it the better choice for use in congest-
ed 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 com-
puter and installing the VRpanel software.
LecNet2 software runs under Microsoft Windows®XP,
VistaTM and Windows 7 operating systems.* An online
Help in the software includes a listing of commands
used to control the Venue through the serial ports.

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 combina-
tion to suit the needs of various applications.
The VRM front panel provides an LCD for system setup,
monitoring and troubleshooting. During normal opera-
tion, the LCD shows RF and audio levels, diversity
status, pilot tone status (where applicable) and transmit-
ter 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 Button
Turns the power on and off. A brief press also clears the
spectrum scan data after the spectrum analyzer has
been used. Press and hold the button for a few seconds
to turn the unit off.
Function Button
Used for various functions in selected Setup Screens as
labeled on the LCD.
BACK Button
The Back Button is used to return to the previous menu
or setup screen.
LCD Screen
The LCD is a backlit, graphics-type Liquid Crystal Dis-
play used to set up and monitor system operation.
Controls and Functions
Receiver Select Buttons
The six Receiver Select Buttons are used to select indi-
vidual installed receiver modules, for monitoring via the
PHONES jack and for setup and adjustment.
PUSH FOR MENU/SELECT Rotary Control
This control, called the MENU/SELECT control for
short, is a pushbutton switch and rotary knob used for
navigating and selecting setup menus and screens, and
for selecting parameters within the setup screens.
PHONES Jack and LEVEL Control
The LEVEL control is used to adjust the output level
of the front panel PHONES jack for individual chan-
nel monitoring. It does not affect the output levels at
the rear panel XLR jacks. Only the audio from a single
receiver (or a diversity pair) selected via the Receiver
Select Buttons will be present at this jack.
The PHONES jack can also used as an audio output for
recording when using the Walk Test Recorder.
NOTE: An explanation of the Walk Test Recorder
is presented in the section entitled Setting Up the
Venue Receiver Using VRpanel.

The rear panel provides six balanced XLR audio out-
puts, 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 au-
dio 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 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 distribu-
tion 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 oper-
ates 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.
Note: Venue receivers with a 50 MHz bandwidth
must be on the same frequency block to use the
antenna loop through.

Hardware Installation
Installing/Removing Receiver Modules
Up to six Receiver Modules can be installed in a VRF
chassis. These modules may be installed at the factory
or added later.
Although the VR Field System is quite flexible, any com-
bination of Receiver Modules installed must be within
the frequency block range of the VRF chassis. The
frequency block range of the VRF chassis is displayed
during the PowerUp Sequence.
Frequency Block Range
Installing Receiver Modules
1. Ensure the VR Field System is turned off and the
power source has been disconnected. Slide the
Receiver Module Connector firmly onto the Receiv-
er Module Tab.
Caution: Do not force the Receiver Module
onto the Receiver Module Tab. If the module
does not seat properly, look to see if its
position is a little off. Excessive force may
damage the module’s connector or the
Receiver Module Tab.
2. Install a Receiver Module Retaining Clip between
the rear of the Receiver Module and the Module
Tab. Ensure this clip is firmly snapped into place.
Removing Receiver Modules
1. Ensure the VR Field System is turned off and the
power source has been disconnected.
2. Remove the Retaining Clip and slide the module
outward off the connecting tab and remove it from
the chassis.
Installing the VR Field System
The VR Field Receiver is designed for portable use, as
in a bag system.
1. Position the unit for easy access to the panel con-
trols and connections. There are no special ventila-
tion requirements.
2. Connect the antennas (or antenna cables if remote
antennas are being used) to the antenna input con-
nectors on the rear panel of the VRF.
3. For multiple unit installations, connect coaxial patch
cables from the Antenna A and B OUT jacks on the
rear panel of the first unit to the Antenna A and B IN
jacks on the second unit. An additional unit can be
connected to the second unit in the same manner.
Note: All units connected in this manner must be on the same
frequency block.

Initial Startup
When the Venue receiver is first powered up the LCD
will show the firmware revision and the tuning range of
the host assembly. The wideband version of the VRM
covers the entire 230 MHz bandwidth of frequency
blocks 21 through 29.
As the boot sequence continues, the display will switch
to an overview of all six receiver channels. In this ex-
ample, six receiver modules are installed but no trans-
mitters are turned on. In this case the “P” will be blinking
since no pilot tone is detected.
The wideband Venue receiver is different than the 50
MHz version in that the receiver modules are detected
through a manual process rather than automatically at
boot up. Press the MENU/SELECT control and rotate it
to select “Detect” on the menu.
Press the MENU/SELECT control to launch the detec-
tion process.
It takes about 45 seconds to detect all the modules and
update the memory in the host assembly. Once com-
pleted, the LCD will briefly display the results showing
the frequencies of the installed modules.
If a slot is not occupied by a module, the display will
place an “X” in that position.
The display then switches to the overview of all six
channels.
Any slot that is not occupied by a module will leave a
blank space in the overview display.
If a module in any position has been removed, changed
or added since the last use, the LCD will flash a mes-
sage advising that the Detect process needs to be run
again.
In normal operation with all six channels running, the
overview display will include:
 • Audiolevel
 • RFlevel
 • Diversityantennaphaseactivity
 • Pilottonestatus
 • Transmitterbatterystatus

settings are available that affect the high frequency
audio content and noise:
• NORMAL(factory default) applies a moderate
amount of noise reduction, dramatically reducing
hiss with virtually no discernible side effects.
• FULL applies more aggressive noise reduction with
transparency superior to the noise reduction system
used for many years in the earlier Lectrosonics
wide deviation analog systems.
• OFF applies no noise reduction for complete trans-
parency.
Navigate to the SmartNR setup screen.

Digital Hybrid Wireless™ Modular Receiver System

Select the receiver module with Receiver Select Button
and rotate the MENU/SELECT control to the desired
mode. Listen to the audio signal as you rotate the knob
and select the mode that best fits the situation.
Note: If the selected Receiver Module is part of
a ratio or frequency diversity pair, the mode will
automatically be set for both receiver modules in
the pair.
When any Compat Mode other than Dig. Hybrid is se-
lected, FIXED will automatically be selected.
In this example, receiver modules 4, 5 and 6 are set to
the FIXED mode with no adjustment available.
Selecting Diversity Modes
Navigate to the DivMode setup screen.
Three diversity reception modes are available:
• Switched Diversity uses one receiver module per
audio channel.
• Ratio Diversity (OptiBlendTM)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 com-
bined 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)
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 switch-
ing. 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 out-
puts of both modules.
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 pur-
pose 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 au-
dible 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.
To prepare for operation in the Frequency Diversity
mode, make the following adjustments:
1.Set up the transmitters according to their instruc-
tions. 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
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. Be sure to press INVT one more
time to put the audio from the two channels
back in phase for normal operation.
Selecting the Tuning Mode
Pre-coordinated tuning groups are stored in memory to
simplify frequency coordination. The groups are labeled
GROUP a, b, c and d on the LCD, with eight frequen-
cies stored in each one. Refer to the section near the
back of this manual entitled Pre-coordinated Frequen-
cies for details on compatibility and using these groups.
Select a
through d
Three additional modes are also available to enable
compatibility with non-standard transmitters and storing
custom frequency sets. Navigate to the Tuning menu
and press the MENU/SELECT control.
NORMAL MODE is the standard Lectrosonics mode
with 256 frequencies in 100 kHz steps. A unique pilot
tone is present for each frequency.
FINE MODE allows tuning to 1024 frequencies in
25 kHz steps for compatibility with older and non-
Lectrosonics transmitters. Pilot tone frequency is set to
the next lower even 100kHz frequency. For example,
650.000, 650.025, 650.050 and 650.075 all use the
same pilot tone frequency.
CUSTOM MODE is a special mode used to store up to
50 frequencies per block in 25 kHz steps. Frequencies
are stored in memory in a “table” with positions num-
bered 0 through 49. The pilot tone frequency is defined
by the position of each frequency in the table.
The Receiver Detail window will indicate the selected
mode and frequency information. In the FINE mode
transmitter switch settings will be shown when the
frequency is on an even 100 kHz step. In the CUSTOM
mode the position of the frequency in the table of 50
stored in memory will be shown.

Finding Clear Frequencies with SmartTune
SmartTune simplifies setup by scanning the tuning
range of the receiver and automatically setting a re-
ceiver 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 software.
1. Navigate to the SmrtTun setup screen and press
the MENU/SELECT control.
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 cur-
sor will stop moving and blink briefly on the newly
selected frequency briefly.
3. The display will then switch back to the receiver se-
lection 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.
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.
In most cases the system will be ready to use after
SmartTune has been run on all modules, however, it’s
a good idea to perform a system checkout to verify
the compatibility of the frequencies selected. Refer to
the section entitled Diagnostics near the back of this
manual for details.
Finding Clear Channels with Tuning
Groups a through d
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 and “c” and “d”
are compatible with each. Other combinations require
testing. Refer to the section entitled Pre-coordinated
Frequencies for details on using these groups.
To use groups a through d, complete the following
steps:
1. Navigate to the Tuning setup screen.
2. Select each module in turn with the Receiver Select
Buttons and select the desired tuning group. Then
return to the overview screen.
3. Turn transmitters off. From the overview screen,
open the receiver detail screen for each module
and rotate the MENU/SELECT control to select a
frequency where no RF signal is indicated.
Finding Clear Channels
Using Full Spectrum Scan
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.
1. Turn off all transmitters and set all receiver modules
to the NORMAL tuning mode (not a tuning group).
2. Select Scan from the TopMenu and press the
MENU/SELECT control.

press MENU/SELECT. The scanning begins auto-
matically.
3. Allow the scanner to continue sweeping through the
tuning range several times, then press the Function
button to enter “Stop Mode.”

6. Press the BACK button to return the previous menu
to select the next receiver to use for scanning.
7 . Continue from step 2 to scan all blocks that are
installed.
8. Conduct a system checkout with the procedure
explained in the section entitled Diagnostics.
Adjusting Audio Output Levels
The audio output levels at the rear panel XLR jacks are
software controlled. (The front panel LEVEL knob af-
fects 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.
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.

Button
3. Use the Tone Generator to adjust other equipment
to match the output level from the receiver with full
modulation of the transmitter. Press the Function
Button to start the tone.
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.
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 module with the Receiver
Select Button and adjust the phase with the MENU/SE-
LECT 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 Digi-
tal 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.
1. Navigate to the TxBatt setup screen.

9V TIM Transmitter uses a 9V battery. Display its
voltage normally in the battery level window
but monitor its status with the battery timer
in the main window.
AA ALK Transmitter uses a AA alkaline battery.
Monitor voltage with battery icon in main
window.
AA LTH Transmitter uses a AA lithium battery. Moni-
tor voltage with battery icon in main window.
AA TIM Transmitter uses an AA battery. Display its
voltage normally in the battery level window
but monitor its status with the battery timer
in the main window.
The 9V TIM and AA TIM settings are most useful for re-
chargeable batteries, all or most of which do not exhibit
reliably identifiable voltage drops as they discharge.
In compatibility modes other than 400 Series and 200
Series, no battery telemetry information is available so
the TXBAT setup screen offers only two choices:
NOTIMER Display no transmitter battery status in the
main window.
TIMER Monitor the transmitter battery status with
the battery timer in the main window.
If the selected receiver module is part of a ratio
diversity pair, the battery type will be automatically
set for both units in the pair. If the selected receiver
module is part of a frequency diversity pair, the
battery type is set independently for each receiver
in the pair since there are two transmitters in use.
3. When either the AA TIM or 9V TIM (timer) mode
is selected, press the Function Button to reset
(“ZERO”) the timer.
