Features

Overview: The Atlas Sound TSD-MIX42RT is an ultra-compact 4 x 2 Mic/Line Mixer, designed background music applications where paging and priority music override, as well as remote input selection and level control are needed. It works well by itself, or in conjunction with an amplifier in meeting rooms, luxury suites, digital signage, or other applications. The TSD-MIX42RT requires a separate 24V power supply (sold separately).

Time Saving Devices (TSDs): The TSD-MIX42RT is part of Atlas Sound's Time Saving Devices, or TSDs, for short. TSDs utilize high quality internal components, and were designed to provide efficient and cost-effective solutions to "real world" installation problems. Atlas Sound's TSD line includes mixers, amplifiers, preamps, distribution, and control devices. All of the TSDs are housed in a compact 4" x 1.5" x 2.75" black aluminum chassis.

Priority Paging: You can accomplish Priority Paging on the TSD-MIX42RT by contact closure or VOX trigger on Input 1 that will mute the audio on Inputs 2, 3, or 4, whichever you assign.  You can adjust the sensitivity of the mute circuit using the Mic VOX Sense rotary control on the rear panel.

Juke Box Override: When using the mixer for installations that require audio override sensing, you can assign Input 3 to Juke Box Override. When Input 3 receives a signal, it mutes the stereo Inputs 1 and 2. When audio is no longer present on Input 3, Inputs 1 and 2 fade back in and resume play. You can activate the Juke Box Override feature and select the mute duration at 3 seconds or 20 seconds, using the front panel Dip switches.

Inputs: The TSD-MIX42RT features three unbalanced stereo line inputs (3.5mm) and one balanced mic/line input (Phoenix style connector) with switchable 24V Phantom power (for connecting condenser microphones). The mic/line input features a high quality, low noise internal mic preamp and a 12dB/octave, 125Hz lo cut filter to eliminate rumble. Each input has a rotary level control knob to independently adjust the input signal levels.

Outputs: The TSD-MIX42RT is equipped with two balanced line outputs (left and right) with Phoenix style connectors.

Optional Wall Controller: Remote Input Selection and Level Control can be performed with the optional WPD-MIX42RT Wall Controller. You can remotely select inputs 1, 2, or 3, view which of the inputs are active, and adjust the volume from the wall controller, mounted up to 200 feet away. Eight conductors are needed to connect the wall controller to the mixer. (Cat5 cable can be used, if desired.)

Dip Switches: There are 12 Dip Switches on the front panel for configuring the mixer as you desire:

• Dip Switch #1: 24V DC Phantom Power for Input 4 (Off/On)
• Dip Switch #2: Input 4 Select (Line/Mic)
• Dip Switch #3: Low Cut Filter 125Hz (Off/On)
• Dip Switch #4: Juke Box Override for Input 3 (Off/On)
• Dip Switch #5: Juke Box Override for Input 3 Mute Hold Delay (20 sec/3 sec)
• Dip Switch #6: Input 3 Mute Receive (Off/On)
• Dip Switch #7: Input 2 Mute Receive (Off/On)
• Dip Switch #8: Input 1 Mute Receive (Off/On)
• Dip Switch #9: Outputs (Left Right Stereo/Mono)
• Dip Switch #10: Remote Level (Master/Inputs 1, 2, 3)
• Dip Switch #11: Wall Plate Activation for optional WPD-MIX42RT (Off/On)
• Dip Switch #12: Not Used

Power Requirements: The TSD-MIX42RT does not have a power cord, but requires an external power supply of at least 24V/60mA. The optional TSD-PS24V500MA is a 24-volt power supply, capable of powering multiple TSDs up to 500mA. The power supply has a 2-pin Phoenix connector which plugs directly into the back panel of the distribution amplifier. With the 24V power supply, the TSDs meet Energy Star standards for energy efficiency.

Mounting Options: There are several ways of mounting the TSD-MIX42RT. In addition, two cable retainer straps are included to help make a clean installation. Mounting methods include:

• Velcro: Self-adhesive, industrial-grade Velcro strips are included in the box for attaching the amp to virtually any flat surface.
• Brackets: Two mounting brackets are included in the box to secure the amp to a cabinet or wall.
• Rack Mount: The optional TSD-RMK rack mount panel allows you to mount up to four TSDs in a single 1U rack space.

Security Cover: A security cover is included to prevent potential damage or unwanted tampering with the front panel controls. The front panel knobs are removable to allow the installation of the security cover.
