Extron MIX 301 Three-Input Stereo Audio Mixer
The Extron MIX 301 is a compact three-input stereo audio mixer designed for professional AV presentation systems requiring simple source mixing. It accepts three unbalanced stereo audio inputs on dual RCA connectors and provides a single balanced or unbalanced stereo output on captive screw terminals, with independent level controls for each input. This mixer is ideal for combining multiple line-level sources—such as laptops, media players, microphones with preamps, or consumer devices—into a unified audio feed for amplifiers, DSPs, or presentation switchers in classrooms, conference rooms, boardrooms, training facilities, and control environments.
The MIX 301 features adjustable gain per input (±12 dB), low-noise preamplifiers, and a master output level control for precise mixing balance. Its small form factor allows easy mounting under tables, in racks, or behind equipment, while captive screw output terminals ensure secure, vibration-resistant connections in permanent installations. The passive design requires no external power, delivering reliable, straightforward audio mixing without added complexity.
