Venue 2 Wideband Receiver Introduction Tuning Range Designation The Venue 2 Wideband receiver is a modular rack mount design for use with a wide variety of transmitters from Lectrosonics and other manufacturers. The VRM host assembly covers three frequency bands, and the VRT modules covers a single band (three Lectrosonics blocks) as shown at right. VRT modules can be installed in any combination or sequence within the three band range of the host mainframe.
Digital Hybrid Wireless® Modular Receiver System Important Safety Instructions This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure -- voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Please read the manual.
Venue 2 Wideband Receiver Front Panel Infrared port Rotary encoder Receiver select buttons The Venue 2 receiver mainframe (VRM2) serves as a “host assembly” for up to six receiver modules. The tracking receiver module (VRT2) can be mixed and matched in the assembly in any combination to suit the needs of various applications. The mainframe front panel provides an LCD for system setup, monitoring and troubleshooting.
Digital Hybrid Wireless® Modular Receiver System Rear Panel Balanced audio outputs Antenna inputs ( ) ( ) Antenna outputs (loop thru) 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 mainframe.
Venue 2 Wideband Receiver Hardware Installation Removing Receiver Modules Receiver Modules All modules must be within the frequency passband of the host assembly. Frequency bands are marked on the receiver modules. When a module is set for Smart Diversity (antenna phase switching), receiver modules can be installed in any position in the mainframe chassis.
Digital Hybrid Wireless® Modular Receiver System Audio Outputs Balanced XLR audio outputs on the rear panel can be used to drive balanced or unbalanced inputs at line level on any type of mixer, recorder or other type of audio equipment. ( ) ( ) Note: When the modules are paired for diversity operation, the audio will appear at both XLR jacks associated with the module pair.
Venue 2 Wideband Receiver LCD Interface When the receiver is turned on, LCD will show the model number, firmware version and serial number during the boot sequence. When the sequence is completed, the Main Window will display the status and activity of the installed receivers. Setup and monitoring can be done directly on the front panel keypad interface. It is worthwhile to become familiar with the front panel controls even if you only use it for monitoring and to check settings.
Digital Hybrid Wireless® Modular Receiver System Using Setup Screens When a menu item is selected, a setup screen will open to enable adjustments and settings to be made. The setup screen may be for a simple, two-state setting like Lock/Unlock, or may provide a display that allows scrolling through the available receiver modules and options, or include multiple settings. Examples of the various screen types are presented below. The Lock/Unlock screen is typical of the single item screens.
Venue 2 Wideband Receiver Setup Details Audio Output Levels Setup Direct Access to Receiver Setup The output level of the installed receiver modules can be adjusted in a single setup screen in the RX Menu. Basic adjustments to each receiver can be made in a single screen available with the numbered Receiver Select button below the frame of each receiver. These buttons operate only from the Main Window. Icons representing “sliders” are presented for level adjustments.
Digital Hybrid Wireless® Modular Receiver System Optimizing the Signal to Noise Ratio Modulation (audio level) Given the information above, the optimum signal to noise ratio is achieved when the least amount of gain is applied to the signal, since gain (amplification) is the source of noise buildup. The transmitter input preamp is the low noise gain stage at the beginning of the signal chain. The ideal setup is to have this be the only gain stage, and subsequent stages be at unity (zero gain/loss).
Venue 2 Wideband Receiver Talkback Setup Group Tuning Talkback is a special function that re-directs the audio output of the transmitter in use to a different receiver module when a button is pressed on the transmitter. The normal use is to provide a “com” channel so the person using the transmitter can have a direct line to the crew or production staff. The HH hand held transmitter provides a programmable switch on the housing that can be configured for this function.
Digital Hybrid Wireless® Modular Receiver System Top Menu SYSTEM INFO Firmware and hardware versions and the serial number of the unit is listed in the SYSTEM INFO screen. IR Transmitter Setup The IR (infrared) port simplifies transmitter setup by sending the settings saved in the receiver to an IR enabled transmitter. The IR port is located on the receiver front panel next to the power switch. The transfer is initiated by the receiver.
Venue 2 Wideband Receiver Smart TuneTM Clear frequencies can be discovered automatically using the SmartTuneTM utility. Navigate to SMART TUNE in the TOP MENU and press the encoder. A listing of the installed receiver modules will appear. After selecting the receiver to use for the scan, select START and press the encoder. The START item will change to STOP while the scanning is taking place. The scanning will build a graphical representation of the RF activity within the tuning range of the receivers.
Digital Hybrid Wireless® Modular Receiver System Firmware Update Firmware updates are detailed in the Wireless Designer software help file. Launch the software and click on Online Help, then on Venue2 Receiver Setup and Monitoring, then on the item for updating firmware. 5) Open Wireless Designer, and proceed to update the firmware using the normal steps, EXCEPT be sure to click and mark the “Recovery Mode” check box at the bottom of the screen.
Venue 2 Wideband Receiver TOP MENU Menu Map TOP MENU DETECT takes an inventory of the receiver modules installed in the mainframe and displays the results in an on-screen table. DETECT SMART TUNE is an automatic process that scans the tuning range of all modules and automatically finds clear frequencies. The screen prompts the operator to set up transmitters one at a time to the newly discovered frequencies and turn them on before proceeding.

NOTE: The setting for 100 or 25 kHz frequency increments is in the TX Menu under STEP SIZE, selectable on a per channel basis. AUDIO LEVEL is used to adjust the output level of each receiver. The built-in tone generator is also enabled in this screen.
Digital Hybrid Wireless® Modular Receiver System Connecting to a Network A basic network is composed of several devices: • Router or server • Ethernet switch • Client devices An example of a simple network is a modem used in a home for internet access via a telephone or cable TV connection. There are actually three different devices built into the box that is typically called the “modem.
Venue 2 Wideband Receiver 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.
Digital Hybrid Wireless® Modular Receiver System Antennas Use and Placement The Venue 2 mainframe 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.
Venue 2 Wideband Receiver Front Mounted Antennas The internal coaxial cables and connectors can be moved to the front panel if so desired, using small flat blade and Phillips screwdrivers. WARNING: Always unplug the receiver before performing this procedure. Step 1 Step 3 Remove the four screws holding the chassis cover, then remove the cover by lifting the rear up. CAUTION: The exposed components on the circuit board are sensitive to static shock.
Digital Hybrid Wireless® Modular Receiver System Step 5 Step 9 Align the flats on the BNC connectors with the flats in the holes in the front panel and secure them with the lock washers and nuts. The coaxial cables should route toward the front of the receiver as shown so the cable fits loosely under the jack covers. Finger tighten the SMA connectors on the circuit board.
