Venue Modules

VRS and VRT Modules

TECHNICAL DATA

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 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.

Receiver Modules

The VRS standard module has fixed front-end filters that
cover its 25.5 MHz tuning range. The higher selectivity
VRT module has a much narrower tracking front-end
filters that retune as the frequency is changed to stay
centered over the selected frequency.

The modules are a triple conversion, frequency
synthesized design, controlled by the microprocessor
in the host assembly. A common DSP in the host
assembly is used for all six receiver modules to decode
the received signals and restore the digital audio. Using
a single DSP results in a significant reduction in cost
per channel.

Hardware Installation

Retaining Clips

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.

2. 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.

Caution: Make sure the connectors align
correctly. Do not force the module onto the
tab. Excessive force may damage
the connectors.

3. 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.

The host assembly will handle up to six receiver
modules via multi-pin connectors on the side of the main
housing. The modules are held in place with snap-in
retaining clips. The clips hold the modules firmly but are
easy to remove without tools to make needed changes.

Removing Receiver Modules

1. Turn the power off.

2. Remove the retaining clip by pressing on it
sideways 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.
