Introducing the Atlas Sound TSD-MIX31RL 3x1 Mic/Line Mixer, a versatile and reliable audio solution designed for various applications. This mixer offers two mic/balanced line inputs, conveniently connected via removable Phoenix style connectors, as well as a stereo summing dual RCA input for additional flexibility.

One of the standout features of the TSD-MIX31RL is its switchable phantom power, which allows for seamless integration of condenser microphones. This feature ensures optimal performance and compatibility with a wide range of microphones, enhancing the versatility of the mixer.

To maintain pristine audio quality, the TSD-MIX31RL is equipped with low-noise internal mic preamps. These preamps deliver exceptional clarity and operate quietly, ensuring that the audio signal remains clean and free from unwanted coloration.

Furthermore, each input of the mixer includes a 12dB/octave high pass filter at 125Hz. This filter serves to minimize bass rumble and low-frequency feedback, enabling you to achieve a balanced and controlled sound output.

The TSD-MIX31RL also offers convenient priority paging options. You can activate priority paging through contact closure or VOX trigger on Input 1, which mutes input 3 only. This feature allows for seamless integration of important announcements or priority messages into your audio setup.

For added convenience, the mixer includes a remote level control feature. This feature enables the use of an optional decorative wall plate control, allowing for remote adjustment of either the entire mix bus or input 3 only. This is particularly useful for managing background music inputs or making adjustments in different zones of your audio system.

To ensure system protection and prevent clipping and distortion, the TSD-MIX31RL features a variable output limiter. This limiter actively reduces the risk of audio signal distortion, safeguarding the integrity of your audio output.

Please note that the TSD-MIX31RL requires a power supply (not included) for operation, allowing you to customize the power setup based on your specific needs.

In summary, the Atlas Sound TSD-MIX31RL 3x1 Mic/Line Mixer offers a range of professional features and functionalities to enhance your audio experience. From its versatile inputs and switchable phantom power to its priority paging options and remote level control, this mixer provides the flexibility and control required for various applications. With its variable output limiter and attention to audio quality, the TSD-MIX31RL ensures optimal performance and protection for your audio system. Choose the TSD-MIX31RL for reliable and efficient audio mixing capabilities.
