PRODUCT DESCRIPTION

Biamp's Cambridge Qt

X Series is a complete, all-in-one sound masking

solution that delivers the flexibility, reliability, and ease of installation that

integrators desire. It is engineered to incorporate direct-field technologies,

making the Qt X ideally suited for office environments. Qt X is easily interfaced

with a building's life-safety system out of the box, ensuring proper coordination

during emergencies.

All models of the Qt X control modules include a sound masking generator,

controller, third octave band equalizer and amplifier with two analog audio inputs.

This allows for distribution of audio from paging controllers and/or (background)

music players, one digital media input (RJ45 Ethernet port), and 3 or 6 analog

output channels (depending on the Qt X model) to connect to sound masking

emitters or speakers.

9300 S.W. Gemini Drive Beaverton, OR 97008 USA

FEATURES

• 3 or 6 outputs of sound masking coverage depending upon the model

• Wall, rack mount and plenum options

• Web-based control interface

• Compatible with active and passive Qt

• Qt X is easily interfaced with a building's life-safety system out of the box

• "D" models (Qt X 300D/600D) will support distribution of Dante

and AVB (enabled in future firmware release)

Qt X 300 and Qt X 600: Use direct field devices (Qt Standard or Active Emitters).

The emitters point downward above the listener's head for direct, unimpeded

audio signal. The Qt X 300 control module is a compact three-output controller

suitable for installations of up to 36,000 square feet (3,345 m

control module is identical in features and functions yet supports six outputs of

sound masking and audio installations of up to 72,000 square feet (6,689 m²).

Outputs can be assigned to a zone and then the zones are adjusted for masking

and audio levels and spectra. Qt X 300/600 models have "preset" optimized

sound masking spectra for use with Qt Emitters. Additional configuration is

available from a web-based control interface or from a remote desktop leveraging

the unit's network connectivity with the Qt X software.

The "D" models of each controller (Qt X 300D/600D) will be available in a future

release. They support Dante

audio stream inputs and are AES67 compatible.

The Qt X web-based management software provides an intuitive interface

for setup and programming of a Qt X sound masking system. For information

related to this software interface, see Qt X

Unless otherwise noted, all installation, set up and use instructions apply to the

Qt X family of control modules (Qt X 300 and Qt X 600).

Page 19: Interacting With A Qt X System
INTERACTING WITH A Qt X SYSTEM There are two (2) current methods of accessing and configuring the system Qt X Web Interface (online help file <link>) with differing levels of what can be viewed or affected. The front panel of each unit has very basic functionality - limited to basic information and operating The web interface allows you access or control to: mode of that particular controller.
Page 20 Interacting with a Qt X system (continued) Controller Front Panel Menu / Functionality When the panel is powered up and connected, you can navigate through the basics of the system using the 4 push buttons under the front panel display. What you will be able to view is based on whether the controller is unconfigured (not part of a system) or configured (part of a defined network system).
