Atlas Time Saving Devices
New Atlas Sound Time Saving Devices are designed to solve some of the
common audio system problems in the easiest and in the most efficient
and cost-effective way. Utilizing the highest quality components and
inspired by real world installation issues, the Atlas Sound TSDs include
mixers, amplifiers, preamps, and other distribution and control devices
to simplify your connections, provide specific application needs, and
add flexibility in expansion and changes that prevent expensive system
overhauls.
The Time Saving Devices are loaded with features making it versatile
and user friendly. The TSD design mandate was to make the installation
quick and reliable, saving you valuable time and money. Each model is
housed in a compact 1.5" x 4" x 2.75" footprint that allows for placement
almost anywhere. Common features include removable individual I/O
connectors for quick and precise wiring, separate ground terminals for all
I/Os assuring secured connections, and removable level controls that can
be replaced with a tamper-resistant security cover.
Description
The TSD-ML11 is a high headroom, low noise mic preamp that allows
your ‘money channel’ to have the highest performance possible. Use as
a standalone preamp or in conference room systems, board meetings,
courtrooms, council chambers, and public forums system that need mute
and push to talk microphone functions.
The TSD-ML11 features switchable phantom power for powering
condenser microphones and has four EQ cut filters centered at common
frequencies to eliminate feedback and control voice shaping. The variable
mic preamp helps further eliminate noise for quiet operation as well
as reduces unwanted coloration and changes in tonality and a 12dB @
125Hz high pass filter is available on each mic input to minimize bass
rumble and low frequency feedback in the system and ensure focus
and clarity stays on voice sound spectrum. An output limiter/compressor
is also included for system protection to avoid clipping and eliminate
distortion. Mic Mute and Mic On control allows microphones in the
system to be push-to-talk enabled or muted for speaker priority.
The TSD-ML11 is highly efficient and meets Energy Star™ standards as
one 24V DC power supply (available separately) can power multiple Atlas
Time Saving Devices.
