RTS Zeus II User Manual

Zeus II

Trunking Digital Matrix Intercom System

You need the capabilities, redundancy and programmability of a full-featured, top of the line digital matrix intercom system, but
have limited space in which to add the equipment. You also need to be able to expand the intercom system as your communica­tions needs grow.

The RTS Zeus II matrix intercom system provides 24 channels of high-quality audio in a compact 2 rack unit package with the

added benet of linking to other RTS matrix intercoms via intelligent trunking.

Each channel is capable of supporting any of the RTS line of matrix keypanels, or four-wire inputs and outputs for program, party
line and IFB feeds.

The Zeus II comes complete with AZedit, a Windows based, full-featured conguration software, providing on-line and off-line
programming capabilities.

Features

Redundant power supplies standard

The unit comes complete with two completely independent
power supplies that can be powered from separate AC
feeds. Because of the extremely low power consumption, the
use of low cost UPS units for particularly critical installations
is possible.

Meet any communications needs without rewiring, jump­er changes, or the need to take the system “off-line”

Nearly all changes can be made by the users, using a
keypanel. More involved changes can be made on-line or
off-line using the Zeus-Edit programming software.

Better than CD quality audio

Zeus uses the RTS TDM ASIC to perform all audio switching
and mixing in the digital reel. Input and outputs are convert­ed at 44.1 kHz, 20-bits for a full 20 kHz bandwidth. The TDM

Line Drawing

ASIC performs all DSP with 45-bits resolution, avoiding any
degradation of communications, regardless of the number of
users on a given path.

All communications modes are provided

Zeus comes standard with full support for point-to-point
communications, party-line conferences, IFBs, Isolate, and
special lists.

External interfaces standard

Eight general purpose inputs and outputs (GPIOs) are
provided for control of external devices including two-way
radios, VOXs, tally and alarm indicators. A serial port is also
provided for connection of RTS accessories including ad­ditional GPIO, level control panels, conference assignment
panels and program assignment panels.
