Raising Performance
WBS-670/680 Wireless Intercom Systems
Frequency-agile UHF wireless intercom systems
Whether you’re adding to a wired intercom system or 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.
WBS-670 Single-Channel Wireless
The WBS-670 supports up to four fullduplex wireless beltpacks with its 1RU
base station. Multiple stations may be
used together for larger productions,
tied together via the party-line 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 field-replaceable. The integral LCD
window shows channel and frequency
information, and allows the programming
of beltpack channels and functions.
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 loopthrough 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
co-linear antennas, or a variety of external
antennas may be used. The WBS-670 is
compatible with virtually all wired partyline and matrix intercom systems.
WBS-670/680 Wireless 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 – partyline, digital matrix, or one of each. A variety
of different communication routings are
activated from the beltpacks, with each
beltpack user having limited or full control.
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 or wired intercom
channel B. The WTR-680 beltpack allows
the user to listen and talk on either or both
of the two intercom channels. A “wireless
Frequency-agile UHF Operation
The WBS-670 and WBS-680 operate in
selected frequency bands between 518 –
740 MHz. These bands are each divided
into 740 distinct frequencies at 25 kHz
Adjustable Transmitter Power
The base station transmitter has a highpower setting of 100 mW (WBS-670 is
50mW), a low-power setting of 10 mW
for closer distance use. The beltpack
transmitters have built-in sensing circuitry
that drops the normal 50 mW output by
10 dB when close to the base station.
Pre-Selected Compatible
Frequencies and Frequency Scan
System setup is easy with the 24 internal
preselected and intermodulation-
talk around” button places the user’s voice
on the wireless- only 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 and
onto an auxiliary output with associated
relay on the base station – for paging and
The WBS-680 adds another wired intercom
connector section on the rear panel, plus a
stageannounce 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.
free frequency groups. Aided by the
“scan” function, base stations and
beltpacks can typically be coordinated
and working together within minutes.
Memory locations can be allocated so
that particular sets of frequencies can be
chosen, programmed and saved as a new
Internal Audio Routing Options
Circuit paths on the WBS-680 main
board may be wired, either internally or
externally, to give variable-level duallisten features to the beltpacks. Also
base station internal switching can place
auxiliary audio on beltpack channel B only,
or on both A and B.
Great Audio Quality and Range
The audio quality of the WBS-670
and WBS-680 is on par with that of a
professional party-line or digital matrix
intercom. Efficient antennas and sensitive
receivers lead to excellent range for
reliable use at a distance. A variety of
remote antenna options enhance that
range and help with difficult production
Rechargeable Battery Option
The 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. A 4-bay charger keeps a
system’s worth of batteries at the ready.
