Clear-com RS-703 2-Channel TW Analog Beltpack
Clear-com RS-703 is a two-channel analog TW
beltpack that can carry power and audio through the XLR-3 line connector
using TW partyline. Each beltpack combines high headroom, low-noise audio
and shaped frequency contour (the “Clear-Com Sound”) to deliver clear audio.
Operation
The RS-703 features LEDs on the top of the beltpack
for visual indication of incoming and
outgoing call signaling. A mic
preamp enables intelligible voice communication for every volume level.
Recessed rotary volume control, Talk and Call keys guard against accidental
activation. The RS-703 has low operating current to allow for more beltpacks
in a daisy-chain.
Additionally, a thumbwheel level adjustment is
available for Program In, as well as a 3.5mm TRS jack for balanced mono
Program Input.
DIP Switches and LEDs
A concealed DIP switch panel on the back of the
beltpack allows the capability to select audio
and key options quickly
and easily. DIP switches can control features such as switching between
electret or dynamic headsets, setting a minimum or off level for
headphone output, adjusting volume settings, enabling or disabling LED
signals, having Call on Talk or latching the Talk key for Channel A,
having Call on Talk or latching the Talk key for Channel B, Channel B
Minimum Volume setting, and RTS-TW/Clear-Com Select. A green LED indicates
that the beltpack is powered and a green LED on the Talk key indicates that
the microphone is active (Talk is latched). An amber LED indicates a Call
signal on the channel.
Improved Design
The RS-703 is designed in a rugged and reliable
casing with a retro-design connection to the
previous RS-500 Series
beltpacks. A belt clip allows a variety of ways to use the beltpack;
users can clip it to a belt or lanyard, or users can mount the belt clip to
a wall, pole or desk for fixed installations.
Compatibility
The RS-703 is compatible with any TW capable
partyline intercom systems or peripherals. This beltback requires the use
of TWC-703 TW adaptor when used with a Clear-Com partyline intercom system.
The RS-703 can also be directly connected FreeSpeak® Basestations, ArcadiaTM
Central Station and LQ® IP Interfaces with 2-wire ports configured for
RTS-TW use.
