    Product Guide for the Russound MBX-PRE Wi-Fi Streaming Audio Player — a preamp-only (non-amplified) network streamer with app control, Voice Control (Amazon Alexa / Google Home via Chromecast built-in), and integration with Russound MCA-series systems.

    Overview

    The MBX-PRE is one of two products in the MBX streaming family — the MBX-AMP is a full-featured streaming audio player with a built-in amplifier, while the MBX-PRE is the preamp-only version. Both are designed to add convenient wireless streaming with the quality of Russound entertainment. With Voice Control support for Amazon Alexa and Google Home, the MBX-PRE adds simple, intuitive voice command functionality to any home entertainment system.

    Key Features

    • Works with any Russound MCA-series controller as a fully integrated Russound source, controllable by any Russound MCA-series keypad such as the MDK-C6 or SLK-1. Can also be used with any other amplifier or receiver to add hi-res audio streaming and app control to an existing installation.
    • Added to the home network easily via wired Ethernet or Wi-Fi connection.
    • Convenient USB port for playing music from flash drives or USB hard drives.
    • Built-in 12V trigger to activate an external amplifier.
