2 Clear-Com WBS
Whether you are adding to a wired intercom system or creating
a standalone wireless communications system, the WBS-670
and WBS-680 wireless intercoms are excellent choices. These
systems extend the reach of your communications system in live
performance, studio and mobile television production, industrial
and aerospace applications, or wherever full-duplex wireless
communications are required.
Frequency-Agile UHF Operation
The WBS-670 and WBS-680 operate in select frequency
bands between 470-686MHz. Both wireless systems are
supplied with 24 factory-selected, intermodulation-free
frequencies. Select from factory presets or any suitable
frequency in 25kHz increments. 720 Tx and 720 Rx
frequencies can be selected, each from independent
18 MHz operational bands.
Adjustable Transmitter Power
The beltpacks can sense when operating in close proximity
to the base station and intelligently reduce transmitter
output by 10dB. This effectively eliminates overloading
the base station receiver front end which is the primary
cause of “nearfar” densing problems. WBS wireless
system beltpacks operate in normal power mode for
typical distances. A manual high power setting is available
when operating the beltpacks more than 200ft (160m)
from the base station.
Pre-Selected Compatible
Frequencies and Frequency Scan System setup is easy
with the 24 internal pre-selected and intermodulation-free
frequency groups. Aided by the “ClearScan” function,
base stations and beltpacks can typically be coordinated
and work together within minutes. Memory locations can
be allocated so that particular sets of frequencies can be
chosen, programmed and saved as a new preset.
Graphical User Interface
A clear, backlit LCD screen displays the status of the
beltpacks and provides easy access to all the powerful
features as well as conguration of the operational param-
eters. The LCD displays which beltpack is transmitting,
operating frequencies, and group/channel status.
Superior Audio Quality and Range
The audio quality of the WBS-670 and WBS-680 wireless
systems is on par with that of professional wired partyline
and digital matrix intercoms. UHF frequencies are ideally
suited for operating through obstacles. A variety of remote
antenna options can help improve range in difcult,
interference-prone production environments.
Seamless Connection to Wired Intercoms
WBS wireless systems can interface with a variety of two-
wire partyline, four-wire digital matrix or other wireless
intercom systems. In addition to interfacing with external
intercom systems, the WBS systems provide connections
for auxiliary balanced audio input and output. Wireless
Talk-Around (WTA) and Stage Announce (SA) features are
available on the WTR-680 beltpack.
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. The charger is
available in a four-bay conguration.
