Venue 2 Wideband Receiver

Introduction

The Venue 2 Wideband receiver is a modular rack
mount design for use with a wide variety of transmit-
ters from Lectrosonics and other manufacturers. The
VRM host assembly covers three frequency bands,
and the VRT modules covers a single band (three Lec-
trosonics blocks) as shown at right. VRT modules can
be installed in any combination or sequence within the
three band range of the host mainframe.
The Host Assembly
The Venue 2 mainframe assembly houses the power
supply, the antenna and RF distribution, the user
interface and control ports for up to six receiver
modules. With the modules sharing these resources,
a significantly lower cost per channel is realized with
no sacrifice in performance or quality. The built-in RF
multicoupler allows up to three mainframes to operate
from a single pair of antennas, for an additional cost
savings in a multi-channel system.
iQ Front-end Filtering
Each receiver module features a tracking
TM
front-end filter that travels across the
spectrum to stay centered on the selected
operating frequency. Under certain condi-
tions, the filter parameters change automatically to
minimize IM (intermodulation).
When the incoming RF signal is strong, the iQ filter
switches to a narrowband mode with greater loss for
additional suppression of signals above and below the
operating frequency. This mode is especially useful
in applications such as a live stage production where
transmitters are generally close to the receiver an-
tennas. In these conditions, IM is prevalent, but the
signals that generate it are significantly reduced by the
narrowband filter mode.
When the incoming RF signal level weakens, the filter
switches to a wider bandwidth mode for maximum
sensitivity and extended operating range. The filter
tracks in fine incremental steps so that it is accurately
centered on the operating frequency.
Wireless Designer Software
The software provides an overall view of the
system, including all mainframes connect-
ed. The display is scalable to fit and screen
size and several color themes are provided.
Frequency coordination is fast and thorough. Scan
data may be imported and used in the coordination.
When individual carriers are moved manually, compat-
ibility is instantly recalculated and displayed.
