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.

external 24VDC power supply (sold separately). Because of the TSD’s low power consumption, a
single external power supply may power more than one TSD. Please refer to the specifications
on current requirements in milliamps to match with the appropriate power supply. Please observe
the polarity of the wiring to this connector. Note: It is acceptable to exceed the current
requirements of the TSDs but NOT safe to use a power supply that is below the current
requirement of the device.

Wall Plate Interface
The TSD-MIX42RT is designed to mate with the optional wall plate WPD-MIX42RT. This control
accessory allows you to select Inputs to be sent to the Output, along with a system level control and
a remote system on power indicator. To activate the input selection section, you must assign the
corresponding dip switch. Note: Placement of 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 is 8 conductors,
TSD-MIX42RT and a WPD-MIX42RT. Cat5 cable is ok to use. Note: Juke Box Override will not work
when Remote Wall Plate is activated.

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 them versatile
and user friendly. The TSD design mandate was to make the installation
quick and reliable, saving you valuable time and money. The
TSD-MIX42RT is housed in a compact 1.5" x 4" x 2.5" 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 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 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.
The TSD-MIX42RT can be used in conjunction with a WPD-MIX42RT
decor style wall plate that is designed for remote activation of the
TSD-MIX42RT mic/line mixer. The WPD-MIX42RT features an audio
source slide selector as well as a source volume control. The unit
includes an LED indicator to indicate which source is selected and
if it is active. The unit fits in a single gang electrical outlet and uses
an 8-conductor interface connection that includes a single 4 position
removable Phoenix connector and dual 2 position Phoenix style
connectors. When connected to the TSD-MIX42RT and the Juke Box
Override, any page made through the system will override the selected
source so that the page can be heard clearly.
Priority paging can be accomplished via contact closure or VOX trigger
on Input 1 that will mute Inputs 2, 3, or 4 (assignable). 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 1, 2, 3. 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 highly efficient and meets most energy standards
as one 24VDC power supply (available separately) can power multiple
Atlas Time Saving Devices.
