The RDL TX-J2 is a compact, professional-grade passive audio input module designed to mix and convert two unbalanced line-level audio sources into a single balanced or unbalanced mono output. Part of RDL’s versatile TX Series, the TX-J2 features high-quality transformers that provide excellent hum rejection, ensuring clean, noise-free audio in any installation.
With two gold-plated RCA inputs, the TX-J2 can combine stereo signals into mono or mix two separate unbalanced sources. It is ideal for feeding balanced inputs on mixers, amplifiers, and other audio equipment. The module’s output is available on a detachable terminal block for easy system integration.
Designed for space-limited installations, the TX-J2 can be mounted with RDL’s STICK-ON® style methods or secured to backboards, chassis, or custom panels. It is perfect for AV installations, commercial audio systems, studios, classrooms, and networked audio environments requiring reliable passive audio conversion without added gain.
