EZ-MPA1 Microphone Preamplifier with Compression & Phantom Power

The EZ-MPA1 Microphone Preamplifier is a professional, easy-to-use solution for adding high-quality microphone inputs to any sound system. Designed for both dynamic and condenser microphones, it provides clean, consistent audio with front-panel level control, LED metering, and a built-in audio compressor that prevents overloads, distortion, and clipping during loud peaks.

Whether you're upgrading a commercial audio system or adding a microphone input to a mixer or amplifier with only line-level inputs, the EZ-MPA1 delivers reliable, studio-grade performance in a compact, installer-friendly design.

Clear, Consistent Audio with Built-In Compression

The front-panel compressor switch makes it easy to maintain even audio levels. When engaged, the compressor automatically controls sudden volume bursts—such as loud speech, singing, or microphone handling noise—ensuring the output stays clear and distortion-free.

This makes the EZ-MPA1 ideal for:

  • Public speaking

  • Live performances

  • Paging systems

  • Recording and broadcasting

  • Meeting and conference rooms

Flexible Microphone Support with Phantom Power

The EZ-MPA1 accepts a wide range of microphones through its balanced rear-panel XLR input. With switch-selectable phantom power, it supports both:

  • Dynamic microphones

  • Condenser microphones require phantom power

This flexibility makes it a great universal preamp for mixed-equipment installations.

Dual Line Outputs for Easy System Integration

The preamplified mic signal feeds both left and right channels of the line-level output, available on:

  • RCA jacks

  • MINI (3.5 mm) jacks

This makes the EZ-MPA1 compatible with virtually any mixer, amplifier, or commercial audio device that accepts unbalanced line-level inputs.

Simple Front-Panel Control and LED VU Metering

The front panel includes all essential controls for quick setup:

  • LEVEL control for precise mic gain adjustment

  • Compressor enable/disable switch

  • Dual-LED VU meter for easy visual monitoring

Even non-technical users can adjust audio levels confidently.

Ideal for Professional and Commercial Audio Systems

The EZ-MPA1 is designed for reliable, long-term use in a wide range of applications, including:

  • Houses of worship

  • Restaurants and clubs

  • Meeting rooms and classrooms

  • Conference facilities

  • Studios and production spaces

  • Commercial sound and paging systems

Its combination of clean audio, compression, and flexible outputs makes it a perfect fit for nearly any installation.
