Description
The Atlas Sound TSD-MIX41 4x1 mic/line mixer is ideal for applications where multiple mic or line
sources need to be sub mixed or summed. In House of Worship applications the TSD-MIX41 is
especially useful for combining similar sources such as choir microphones to a single mixer channel.
The unit also works well as a stand-alone mic/line mixer that can be easily interfaced with Atlas
Sound amplifiers. Other applications include restaurants, conference rooms, and schools.
Each input is mic/line switchable with phantom power provided for 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 each input to minimize bass
rumble and low frequency feedback.
The TSD-MIX41 is part of a full line of Atlas Sound Time Saving Devices. These compact (1.5" x 4" x 2.75")
units are designed to solve some of the common audio system problems in the easiest and in the
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-proof security covers. The TSDs are highly efficient and meet Energy Star™ standards as one
24V DC power supply (available separately) can power multiple Atlas Time Saving Devices.

Rear Panel Description
TSD Input/Output connections are removable for easy system wiring. The connector has a 3.5mm
pitch between pins.
1. DC Power Input - Each TSD that requires DC power comes with a 2 position connector for
an 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specications 
on current requirements in milliamps to match with the appropriate power supply. 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.
2. Balanced Inputs 1-4 - Connects to balanced line or mic level sources. Your connection must be
