frequency-agile UHF wireless intercom
Whether you’re adding to a
WBS-670 Single-Channel Wireless
wired intercom system or
The WBS-670 supports up to four full-duplex
wireless beltpacks with its 1-RU base station.
Multiple stations may be used together for
larger productions, tied together via the partyline intercom channel. The WTR-670 wireless
beltpack features a low-profile on/off/volume
control and a momentary/ latching talk button.
Rugged detachable antennas are easily fieldreplaceable. The integral LCD window shows
channel and frequency information, and
allows the programming of beltpack channels
and functions.
creating a stand-alone
wireless communications
system, the WBS-670 and
WBS-680 wireless intercoms
are excellent choices.
Combining frequency agility,
audio clarity, powerful
features, and roadworthiness
with ease-of-use, these systems will extend the reach
of your communications
system in live theatre and
performance, studio and
mobile television production,
industrial and aerospace
applications, or wherever
full-duplex wireless communications are required.
The simple base-station front panel with its
backlit LCD screen gives total control over
frequency and beltpack selection, as well as
control over the input and output level to an
attached party-line or digital matrix intercom
and an auxiliary in and out. If desired, a headphone may be connected to the front panel to
communicate with the wireless beltpacks and
the connected wired intercom system.
The rear panel features 3-pin XLR loop-through
connectors for one channel of party-line
intercom, an RJ-45 connector for direct connection to a digital intercom port, and a pair of
auxiliary connectors. Screw-on TNC connectors
for the base station transmitter and receiver
sections are fitted with a pair of efficient half-
wave collinear antennas, or a variety of external antennas may be used. The WBS-670 is
compatible with virtually all wired party-line
and matrix intercom systems.
WBS-680 Two-Channel Wireless
Like the WBS-670, the WBS-680 supports up
to four beltpacks per base station. This system
adds the ability to connect the wireless beltpacks, via the base station, to two channels
of wired intercom — party-line, digital matrix,
or one of each. A variety of different communications routings are activated from the beltpacks, with each beltpack user having full
control; if desired, the technical director can
lockout unnecessary functions on any individual beltpack.
The WTR-680 beltpack front panel provides a
channel A/B selector button, allowing the user
to talk and listen to either wired intercom
channel A (plus the other wireless beltpack
users on that channel) or wired intercom channel B. The WTR-682 beltpack allows the user
to listen and talk on either or both of the two
intercom channels. A “wireless talk around”
button places the user’s voice on the wirelessonly bus, unheard by those on the wired intercoms. In addition, the beltpacks have a “stage
announce” button, which when activated
places the user’s voice off the intercom line
systems
and onto an auxiliary output with associated
relay on the base station — for paging and
announcements.
The WBS-680 adds another wired intercom
connector section on the rear panel, plus a
stage-announce output and relay contact.
Front-panel controls and indicators give control
and status information about all of these communication connections. Also, a base-station
link connector permits the “wireless talk
around” to be shared among base stations.
Frequency-Agile UHF Operation
The WBS-670 and WBS-680 operate in selected frequency bands between 518 – 740 MHz.
Three different sets are available for compatibility virtually anywhere. An 18 MHz (three U.S.
TV channels) frequency window is used for the
base-station transmitter, with a separate 18 MHz
window for the beltpack transmit frequencies
(base-station receive frequencies). These bands
are each divided into 740 distinct frequencies
at 25 kHz intervals. The WBS-680 has two different base-station transmit frequencies —
one each for intercom channels A and B.
Adjustable Transmitter Power
The base-station transmitter has a high-power
setting of 100 mW (WBS-670 is 50mW), a lowpower setting of 10 mW for closer distance
use, and may be turned off when necessary
for setup and linking. The beltpack transmitters
have built-in sensing circuitry that drops the
normal 50 mW output by 10 dB when close to
the base station, to prevent de-sensing
of its receivers.
Pre-Selected Compatible
Frequencies and Frequency Scan
System setup is a snap using the 24 internal
pre-selected and intermodulation-free frequency groups. Aided by the “scan” function, which
senses the local RF environment and determines which of the frequency groups has the
largest number of clear frequencies, base stations and beltpacks can typically be coordinated and working together within minutes.
A dozen more memory locations are allocated
for user-programmable groups, so that particular sets of frequencies can be chosen, programmed, and saved as a new preset.
Great Audio Quality and Range
Perhaps you’ve experienced that many of the
available options for adding wireless capability
to the intercom system end up sounding like a
telephone or a two-way radio–intelligible but
not great. The audio quality of the WBS-670
and WBS-680 is on a par with that of a professional party-line or digital matrix intercom, so
voice communications and program material
sound more natural and less fatiguing. Efficient
antennas and sensitive receiver design lead to
excellent range for reliable use at a distance.
A variety of remote antenna options, such as
quarter-wave ground-plane and log-periodic,
enhance that range and help with difficult
production environments.
Internal Audio Routing Options
Circuit paths on the WBS-680 main board may
be wired, either internally or externally, to give
variable-level dual-listen features to the beltpacks — one can hear channel A when talking
on B, and vice-versa. This feature is set at the
base station and affects all beltpacks identically. Also, base-station internal switching can
place auxiliary audio on beltpack channel B
only, or on both A and B.
Rechargeable Battery Option
The convenient battery pack will operate the
beltpack in full-duplex mode for 14 hours
with a set of alkaline batteries. The optional
rechargeable NiMH (nickel metal hydride)
batteries will give over 11 hours of continual
use — enough to cover the entire production
from setup to teardown. A 4-bay charger keeps
a system’s worth of batteries at the ready.
