The Extron ATB 100 is a compact breakout adapter that converts a single 3.5 mm stereo mini jack to two color-coded RCA connectors (red/right, white/left) for analog audio signals. This passive adapter enables easy interconnection between devices with 3.5 mm stereo outputs—such as laptops, media players, tablets, or portable sources—and equipment featuring RCA stereo audio inputs, including mixers, amplifiers, AV switchers, or presentation systems. It is well-suited for professional AV installations in classrooms, conference rooms, boardrooms, training facilities, and control environments requiring simple, reliable unbalanced line-level stereo audio bridging without additional converters or power.

The adapter features a 3.5 mm stereo male plug on one end and two molded, color-coded female RCA connectors on the other, ensuring quick channel identification and secure connections. Its short length minimizes excess cable in rack, desktop, or under-table setups while providing dependable signal transmission in mixed-format AV systems.
