EZ-MPA2X

RDL EZ-MPA2X - Dual Microphone Preamplifier with Stereo Output and Compressors

The RDL EZ-MPA2X is a dual-channel microphone preamplifier with built-in compression, designed for professional and commercial AV installations. It supports two dynamic or condenser microphones (with 24 V phantom power) and delivers the amplified signal to stereo RCA and mini-jack outputs.

Each channel features independent level control and LED VU metering for precise adjustment. A front-panel switch enables the audio compressors, which help prevent clipping and manage high dynamic range signals. All input and output connections are located on the rear panel for clean integration in rack-mounted or fixed systems.

Functionality

• Dual-channel microphone preamplifier with independent level controls
• Switchable audio compressors for both channels
• Supports dynamic and condenser microphones (24V phantom power)
• Amplified mic signals routed to stereo RCA and mini-jack outputs
• High headroom increases with lower gain settings
• Integrated high-pass filter (6 dB/octave at 20 Hz)
• Dual LED VU meters for left and right channels
