Applications

AtlasIED has been developing, manufacturing, assisting and
commissioning sound masking systems for over forty years using
proprietary Chanaud masking filters. The Z Series includes a multitude
of features enabling it to conform to most design requirements but
remains intuitive enough for simple operation and quick installation. The
Z Series is designed to be aesthetically pleasing for office or conference
room applications seamlessly blending in to a variety of decors. Z Series
placement is flexible allowing for mounting on a surface, in the wall, or
in an equipment rack.

The Z2-B model delivers quality audio and speech privacy in spaces
up to 7000 sq ft with two-zones of control flexibility. The Z4-B model
features four-zones of audio with total potential sound masking coverage
of up to 14,000 sq ft. This compact integrated solution features out
of the box selectable system configuration presets that are accessible
through the front panel display and navigation keys. The combination of
these features makes for a simple but effective speech privacy and audio
control solution.

General Description

The Z Series is a multi-zone speech privacy system that also supports
background music and paging applications. Model Z2-B is a two-zone
speech privacy system providing 60-watts of total amplification and
model Z4-B is four-zone speech privacy system delivering up to
120-watts of amplification.

The Z Series is an all-in-one solution that not only supplies high quality
speech privacy, but also can deliver high quality background music
and paging. Mic/line and music inputs each have a five-band equalizer
and Hi and Lo pass filters to assure maximum performance. Music
inputs incorporate either analog stereo summed inputs or Bluetooth®
streaming. For paging applications, the Z Series incorporates a unique
hi-Q feedback filter specifically tailored to the vocal frequency range.
Output limiters are in the audio chain to protect against system
overdrive.

Advanced features of the Z Series include separate analog masking
generators per zone, 14-day system commissioning ramp per zone, and
PC project design software allows system custom project files to meet
installation needs.

For conference room applications where secure speech privacy
is required, the Z Series features a Speech Privacy Enhancement
mode that can be engaged while a meeting is in progress. Speech
Privacy Enhancement mode applies additional acoustical energy to
the surrounding environment, increasing the privacy levels for the
conference room occupants. These unique secured speech filters have
been approved and implemented in many installations around the world
including military and government facilities. Activation of the Speech
Privacy Enhancement feature is accomplished via hardwired switch, an
iOS® or Android® application, or using an optional wireless desktop / wall
mount switch. An optional wired or wireless sign is available for a visual
aid to notify attendees when Speech Privacy Enhancement is active.
