About RDL EZ-MPA1

Let the EZ-MPA1 Microphone Preamplifier elevate your audio experience. This high-quality, professional-grade preamplifier is equipped with a front-panel volume control and audio level metering, offering precise control over your sound. With the flip of a switch, engage the built-in audio compressor to effectively manage overloads and prevent clipping during high-level audio bursts or peaks from the microphone.

Designed to support both dynamic and condenser microphones, this versatile preamplifier features a rear-panel switchable phantom voltage. The preamplified mic signal is efficiently fed into both channels of the line output, available on RCA or MINI jacks. LED VU metering further enhances the user experience by facilitating easy level adjustment.
