Alice MPX DA – Multiplex MPX Distribution Amplifier

Product Overview

The Alice MPX DA is a compact 1U multiplex distribution amplifier designed to fan out a single composite MPX feed to multiple destinations in an FM transmission chain. It takes one wideband MPX input and provides six buffered outputs, allowing you to feed main and standby transmitters, changeover units, silence detectors and remote monitoring receivers from a single high-quality source. Front-panel gain control lets you trim MPX level for each installation so deviation and pilot levels remain within specification at every downstream device.

Key Features

• 1U 19″ rack-mounted multiplex MPX distribution amplifier for FM broadcast chains.
• Single MPX input feeding six individually buffered outputs for reliable multi-point distribution.
• Front-panel adjustable gain with a typical range from about -10dB to +20dB for level optimisation.
• 75 ohm impedance on input and outputs with BNC terminations for easy integration with existing MPX cabling.
• Wideband frequency response from 20Hz to 20kHz within ±0.2dB and very low phase shift for accurate composite signal delivery.
• Low distortion performance at typical MPX operating levels for clean audio and pilot tone preservation.
• High signal-to-noise performance for use at main studio, STL receive or transmitter sites.
• Universal AC mains operation across 85–250V AC for flexible deployment.

Applications

Use the Alice MPX DA wherever a single stereo encoder or FM processor must feed several transmitters, standby paths or monitoring points without compromising signal integrity or level stability.

Pair the Alice MPX DA with a high-performance FM audio processor or stereo encoder from our audio processing range to build a complete FM transmission chain. For other distribution tasks, see our distribution amplifiers category and the dedicated Alice brand page on Broadcasters Warehouse.
