AtlasIED TSD-MIX41 4x1 Mic/Line Mixer with Phantom Power

The AtlasIED TSD-MIX41 4x1 Mic/Line Mixer is a compact professional audio mixer designed to combine up to four microphone or line-level sources into a single balanced output. Ideal for houses of worship, schools, conference rooms, restaurants, and commercial sound systems, the TSD-MIX41 provides flexible audio mixing without requiring a full-size mixing console.

Each of the four balanced inputs can be independently configured for microphone or line-level operation, making it easy to connect different audio sources. Professional low-noise microphone preamplifiers deliver up to 50 dB of gain, while individually switchable 24V phantom power supports compatible condenser microphones.

To improve speech intelligibility and reduce unwanted low-frequency noise, each input includes a selectable 125 Hz high-pass filter with a 12 dB/octave slope. Individual input level controls, a master output level control, and signal and peak indicators help installers establish the proper audio balance.

The TSD-MIX41 features removable Phoenix-style connectors, a high-gain balanced line output, and security covers for its front-panel controls. Its compact AtlasIED Time Saving Devices (TSD) Series chassis is suitable for standalone mounting or integration into equipment racks using optional mounting accessories.

Features and Benefits

Four Independently Selectable Mic/Line Inputs

The TSD-MIX41 provides four balanced inputs that can be individually configured for microphone or line-level signals.

This allows installers to combine multiple microphones, audio playback sources, or other compatible equipment into a single mixed output.

For example, several choir microphones can be combined before feeding one channel of a larger sound system.

Professional Low-Noise Microphone Preamplifiers

Each input includes a high-quality microphone preamplifier designed to provide clear audio reproduction with minimal unwanted noise.

With up to 50 dB of microphone gain, the TSD-MIX41 accommodates a range of compatible microphone sources while maintaining appropriate signal levels.

Individually Switchable 24V Phantom Power

Each microphone input supports independently selectable 24V DC phantom power for compatible condenser microphones.

This provides installation flexibility when combining condenser microphones, dynamic microphones, and line-level sources in the same system.

Selectable 125 Hz Low-Cut Filter

Every input includes a defeatable 125 Hz high-pass filter with a 12 dB/octave slope.

The filter helps reduce low-frequency rumble, handling noise, and other unwanted bass energy that can interfere with speech clarity.

This is especially useful for paging, presentations, choir microphones, and spoken-word applications.

Balanced Line Output for Professional Audio Systems

The TSD-MIX41 combines its four inputs into one balanced line-level output.

The output is designed to interface with compatible commercial amplifiers, signal processors, and larger mixing systems. Balanced connections help reduce interference over appropriately installed cable runs.

Individual Input and Master Output Controls

Four independent input level controls allow users to balance connected sources.

A separate master output control provides adjustment of the combined signal level before it reaches downstream equipment.

Signal and Peak LED Indicators

Front-panel indicators provide visual feedback to assist with signal setup.

Green signal and red peak indicators help installers monitor output activity and identify excessive levels before clipping occurs.

Compact Design with Installation-Friendly Connections

The TSD-MIX41 uses removable Phoenix-style captive-screw connectors for its audio inputs and output.

Its compact aluminum chassis includes mounting accessories and removable control knobs with security covers, helping protect established audio settings against unauthorized adjustment.

Energy-Efficient 24V DC Operation

The mixer requires 24V DC power at 60 mA, making it suitable for compact commercial audio systems.

A compatible AtlasIED TSD power supply is required and sold separately. Multiple TSD devices may share an appropriately rated power supply when their combined current requirements are considered.
