The RT12H is a compact, handheld controller designed for acoustic hailing and dispersal systems. Featuring a 1.54-inch display with 128×64 resolution and physical function buttons, it provides intuitive one-handed control in the field. With dimensions of 169mm × 50mm × 118mm and a weight of only 0.81 kg, it is built for portable, vehicle-mounted, and fixed-site operation. Equipped with a Mode key and clearly defined control zones, it manages multiple operating modes—talk, dispersal, music (with USB playback), recording, Bluetooth, and wireless microphone—supporting voice announcement, volume adjustment, warning-tone activation, and one-touch crowd dispersal. Its clear on-screen status and blind-operable button layout ensure reliable use without training. The controller includes a USB port, microphone jack, and upgrade interface, and connects to compatible acoustic devices via a wired aviation connector, ensuring broad compatibility with our company's range of directional, omnidirectional, and handheld acoustic devices that support this protocol, along with OEM/ODM customization services.
