Clear-Com BS850 Base
Station with Power Supply |
|
Product Code: BS850
 |
|
Highlights of BS850: |
•
Frequency agility
enables you to operate the PRO850 within the 470-698 MHz UHF
band. These synthesized frequencies can be selected in 25 kHz
increments over each18 MHz operational band so you can easily
choose from 720 different transmit and 720 receive frequencies.
The upper band is limited to 12 MHz and 480 receive frequencies.
• User-friendly
graphical interface on the
base makes it easy to set up the system and obtain status
information using the LCD display and menu keys. Pull-down menus
on the LCD provide fast, easy access to all system features.
Menus are organized by status, audio-level monitoring, system
configuration and system information. Simple navigation buttons
and multi-function rotary knob facilitate the setup and access
of desired features.
• PC interface
using HME's PC850 software lets you configure the entire PRO850
System and manage configuration files from the convenience of
your PC via the RS-232 serial port.
• Expandable
system allows you to
configure the PRO850 to meet your communication needs. A
standard PRO850 System comes with four beltpacks and a base
station. By linking several base stations to provide additional
receivers, up to 16 users can communicate with each other in
full-duplex operation.
• Automated
beltpack output power control
helps optimize the system operating power. The base station
automatically configures beltpack settings and calibrates the
power level for each beltpack, depending on its distance from
the base. This eliminates base receiver overload and extends the
beltpack battery life.Intermodulation-free frequency groups have
been pre-configured to help you easily scan and select the best,
interference-free frequency groups when you set up the PRO850.
The savvy user can also configure additional frequency groups
for a quick recall.
• Alert relay
output provides a
configurable set of contacts that can respond to problem
conditions or to beltpack user requests.
• Audio
digitally mixed and routed
under user control allows any combination of inputs to be mixed
and delivered to any output. These settings can be preset and
saved to provide different mix configurations for different
shows.
• Remotely
“unlatch” beltpacks from
transmitting at the base to stop a rogue beltpack that’s been
left transmitting without having to locate the beltpack.
