The Extron MVC 121 xi is a compact, three source audio mixer featuring audio DSP for mixing and signal processing. The MVC 121 xi provides a stereo line level input and two mic/line level inputs with 48 volt phantom power for condenser microphones, plus fixed and variable stereo line level outputs. It offers gain, filters, bass and treble tone controls, and parametric EQ. Quick and intuitive configuration using DSP Configurator Pro software allows the MVC 121 xi to be set up in very little time. The MVC 121 xi is ideal for presentation applications that require line and microphone audio mixing with audio DSP in a small form factor.

Audio DSP

The audio DSP built into the MVC 121 xi provides wide dynamic range and utilizes 24‑bit audio converters with 48 kHz sampling to maintain audio signal transparency. Convenient, easy‑to‑configure tools are available to control levels, filters, dynamics processing, bass and treble shelving filters, and parametric EQ.

Easy-to-Use DSP Configurator Pro Software

DSP Configurator Pro software features an intuitive on-screen layout that offers fast access to digital audio signal processing tools as well as audio mixing. Designers can quickly get a snapshot view of the entire audio system, including processing blocks and mix points.

Flexible Mixer

The MVC 121 xi features a stereo line level input and two mic/line level inputs, each of which are mixed into the fixed and variable stereo line level outputs. It is a quick and effective audio mixing solution for adding microphone capability to a new or existing system. The variable line level output can be sent to a PA system, while the fixed line level output can be routed to an assistive listening system.

Versatile Control Options

The MVC 121 xi can conveniently be controlled and configured via RS‑232 serial control or USB. It also includes digital input ports, which allow for external muting control without a control system.
