Installation and Operation Guide
Qt X Sound Masking System
CONTENTS
This manual is divided into sections with installation instructions for each control
module and basics regarding the sound masking devices connected to each.
IMPORTANT SAFETY INFORMATION
Install the controller away from heat sources, such as vents, radiators, and heat
registers. Avoid installing near water. Do not exceed the maximum ambient
operating temperature of 40-90° F (4-32° C).
If the Qt X controller is installed in a rack, the following must be observed:
• Care must be taken to ensure temperature and air flow is sufficient to
allow the unit to operate safely and not exceed the maximum operating
temperature stated above. The controllers must be mounted to the rack in
a safe and stable manner to prevent any potential for tipping or structural
failure.
• Electrical connections to the equipment must be sufficient to prevent any
circuit overloading and reliable grounding of the supply circuits shall be
maintained.
The controllers are UL 2043 approved for installation into a plenum space.
DANGER: The AC/DC power supply provided with this product has not
been evaluated to UL 2043 and must not be installed in a plenum space.

BEFORE YOU START
It is very important to understand the basics of sound masking before installing
a system. Sound masking is the addition of a specifically tailored (frequency)
signal which is added to a listener’s environment to increase speech privacy.
In open offices, the addition of sound masking decreases the distance where
unwanted conversations can be clearly understood, thus reducing the distraction
of those distant conversations. This is accomplished by reducing the talker’s
signal-to-noise ratio as experienced by the listener. (i.e. covering the talker’s
speech with a masking signal at the listener's location).
Sound masking signals (produced by emitters and loudspeakers) are placed
where potential unwanted listeners are present. Placing masking only near a
talker has no effect. In the case of enclosed spaces, it is typical to place sound
masking both inside and outside an enclosed space to maintain speech privacy.
Sound masking signals placed outside of the enclosed space prohibit in-room
conversations from being overheard by people passing near the space. Placing
sound masking inside a room helps to promote speech privacy by “protecting”
conversations taking place in adjoining spaces (such as private offices).
There are several items that you need to know and have in place prior to installing
a Qt X sound masking system:
• Network connectivity - Make Cat 6 cabling runs to all controller locations -
1-2 per controller. (2nd cable would be for future networking capability)
• For installation of Qt X 300/600 systems, an understanding of how runs to
the standard and active emitters are laid out to prevent signal interference
- see explanations in the emitter wiring and layout section (
)
• Familiarity with basic network installation best practices
• You should have the design plan / layout from the Biamp Design Team
noting device, output and zone locations. This will allow you to plan the
cabling runs and controller locations.
