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.

The Atlas Sound TSD-ML22VCA is a 2 input, 2 output true VCA with
enhanced features including a high quality microphone pre amplifier.
VCA’s inserted prior to amplification provides a far more efficient solution
than transformer-based attenuators for volume adjustment in high power
music applications. The dual channel design can provide level control for
two separate discrete zones or stereo sources and is perfect for use in
sports bars, restaurants, hotels or other installations.
The TSD-ML22VCA also provides two high quality, low noise mic
pre-amps, which allows simplification of designs that require remote
microphone level adjustment. Switchable phantom power is provided
for powering condenser microphones and a 12dB/octave @ 125Hz high
pass filter is available on each mic input to minimize bass rumble and low
frequency feedback in the system ensuring focus and clarity for the voice
spectrum.
The TSD-ML22VCA is highly efficient and meets Energy Star™ standards
as one 24V DC power supply can power multiple Atlas Time Saving
Devices (available separately).
