Description
The versatile Atlas Sound TSD-MIX42RT 4x2 mic/line mixer is ideal for applications where paging,
priority music override and/or remote input selection with level control are required. Use alone or in
conjunction with amplifiers in meeting rooms, digital signage, luxury suites, and/or other applications
requiring versatile, stereo or mono multi source mix control.
The unit includes one mic/balanced line input via removable Phoenix style connector and three
stereo 3.5mm inputs. Switchable phantom power is provided for the mic input to facilitate condenser
microphones. The high quality, low noise internal mic preamps ensure clarity and quiet operation
without unwanted coloration. A 12dB/octave high pass filter @ 125Hz also is available on the mic
input to minimize bass rumble and low frequency feedback.
Priority paging can be accomplished via contact closure or VOX trigger on Input 1 that will mute
Inputs 2, 3, or 4 (assignable). A remote level control feature allows use of the Atlas Sound AAVC-10K
or WPD-VC10K decorative wall plate control for convenient remote adjustment of either the entire
Master mix bus or Inputs 2, 3, or 4.
Remote Input selection and level control can be accomplished by using the optional WPD-MIX42RT
wall controller. The WPD-MIX42RT can be placed up to 200 ft away from the TSD-MIX42RT. The audio
quality is not affected by the distance because no audio is present at the WPD wall controller. All that
is needed to obtain maximum system control are 8 conductors, a TSD-MIX42RT and a WPD-MIX42RT.
There are several installations that require audio override sensing for applications such as a Juke
Box’s playback or digital signage advertisement. The TSD-MIX42RT is ideal for these types of
installations. When Input 3 is assigned to Juke Box Override and receives a signal, it mutes stereo
Inputs 1 and 2. When the audio is not present on Input 3 for 20 seconds, Inputs 1 and 2 fade back in
and resumes play.
A variable output limiter provides system protection by reducing clipping and distortion - which is
especially useful when mixing mic and/or line sources with varying volumes.
The TSD-MIX42RT is part of a full line of Atlas Sound Time Saving Devices. These compact
(1.5" x 4" x 2.5") units are designed to solve some of the common audio system problems in the easiest,
most efficient, and cost-effective way. All models are made from high quality components and
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
tamper-resistant security covers. The TSDs are highly efficient and meet most energy standards as
one 24V DC power supply (available separately) can power multiple Atlas Time Saving Devices.
