DIGITAL | NETWORK
In addition to low-latency
distribution, Q-LAN supports
much higher channel capacity
than competing systems
(— up to 512 bidirectional
channels —) and greatly
simplifies implementation
of full system redundancy.
Q-Sys also supports long-haul
IP streaming of audio over
Wide Area Networks (WAN)
as well as auto-discovery and
configuration of end nodes.
Since specialty semi-conductors
and non-standard hardware
can lead to dependence on
obsolete technologies, Q-LAN
is based instead on standards
and protocols from the IT
industry, where a huge market
guarantees ongoing support
and development. Q-LAN
uses widely available off-the-
shelf Gigabit switches. And
Q-LAN’s use of Layer 3 (TCP/
IP) protocol allows transmission
of Q-Sys audio with other IT
traffic, eliminating the need for
facilities to run a dedicated audio
network. The result is a system
that takes maximum advantage of
the capabilities of standards-based
IP networking, achieving outstanding
performance while maximizing
network compatibility.
While Q-LAN is the ideal network for a
fully-integrated Q-Sys environment, QSC
also offers a CobraNet card for interfacing
with legacy systems. At the same time,
the Q-Sys architecture is designed to
allow future compatibility with alternative
protocols such as AVB if and when they
achieve widespread adoption.
TSC-8 Touch Screen Controller
Whether you’re recalling a few simple
snapshots or using faders, knobs,
and buttons to manipulate multiple
parameters, touch screens provide an
ideal user interface for system control.
With capacitive touch technology and a
bright 800 x 600 full-color LCD, the dual-
port TSC-8 makes the perfect networked
controller, not only for Q-Sys parameters
and functions but also for managing a
wide variety of equipment via the Q-Sys
Core’s General Purpose I/O (GPIO) and
TCP/IP instruction sets. Multiple TSC-8s,
each using a different interface created in
Q-Sys Designer, may be attached to the
network simultaneously, with each unit’s
display updated automatically as changes
are made with other units.
Q-LAN
Q-LAN is a blazing-fast Gigabit Ethernet
implementation that delivers audio from
any end-node to the Q-Sys Core in less
than 1/3 millisecond. Q-LAN’s speed
and capacity allow Q-Sys to deliver
overall system latency — including
core processing and both A/D and
D/A conversions — of less than 2.5
milliseconds from any input to any output
with up to seven network switch hops.
Q-Sys™ Page Station
Enabling live paging to selected
zones, the Q-Sys Page Station
extends Q-Sys functionality in
transportation, hospitality, medical,
and other similar applications.
Available with either gooseneck or
handheld microphone (push to
talk), Q-Sys Page Station is a dual-
port network device that is fully
configurable from Q-Sys Designer.
A front panel user interface
includes a capacitive touchpad
that offers visible feedback and
audible cues. Paging status,
alerts, and operational details are
also reported via illuminated status
indicators and a built-in LCD display.
