The Drawmer 4X4R is a 4-in/16-out mic/line signal splitter designed for exceptional audio quality and reliability in demanding environments. With four studio-grade mic/line preamps delivering up to 66dB of gain and sixteen balanced outputs with optional transformer isolation, it provides pristine signal distribution for live sound, broadcast, sports, recording, press, and corporate applications.
Each of the four channels includes a studio-grade mic/line preamp with variable gain, 48V phantom power, mic/line switching, and independent bargraph metering. A headphone monitor output allows quick and easy signal checks, while active splitting ensures clean, consistent levels even over long cable runs. The 4X4R can be configured as 1x 16-out, 2x 8-out, 1x 12-out plus 1x 4-out, or 4x 4-out setups, giving complete flexibility across a wide range of audio distribution needs.
Built into a rugged 1U rackmount chassis, the 4X4R features comprehensive linking options and optional transformer isolation for maximum signal integrity and versatility. Designed and manufactured in the UK, it's the dependable solution for professional audio distribution in fixed installations and touring racks alike.
