Advanced stereo signal routing for modern rigs The KMA Machines Active Stereo ABY is a premium stereo signal router designed for players who demand maximum flexibility without compromising tone. Whether you're splitting one stereo signal between two amplifiers or pedalboards, combining two stereo sources into a single destination or switching instantly between complete stereo rigs, the Active Stereo ABY delivers reliable, noise-free operation while preserving the integrity of your signal. Unlike traditional passive ABY switchers, the Active Stereo ABY features a high-quality buffered design that helps prevent signal loss over long cable runs while minimizing level mismatches between connected devices. A dedicated 180° Phase switch makes it easy to correct phase issues when combining amplifiers or parallel signal paths, while the Direction switch allows the pedal to operate as either a one-to-two splitter or a two-to-one combiner, making it equally at home in guitar, bass, synth or studio setups. Active silent CMOS soft switching provides virtually silent operation by dramatically reducing the mechanical noise, pops and clicks often associated with conventional ABY boxes. Clear three-color LED indicators instantly display whether Output A, Output B or both are active, allowing you to confirm your routing at a glance, even on a dark stage. Designed and built in Berlin, Germany, the Active Stereo ABY combines premium construction, top-mounted jacks and intuitive operation into a compact pedalboard-friendly enclosure. Whether you're building a sophisticated stereo effects rig, running multiple amplifiers or integrating studio equipment, it provides dependable switching with the flexibility today's modern setups demand.
