Very simple small device with 1 input and two outputs, using a button switch to select which output the input signal is routed to. Passive design with all gold-plated XLR sockets; the switch is a single-pole double-throw XLR 123 pin. Optimized for noise-free switching with a non-common ground design. Simple and intuitive condenser/dynamic microphone signal switcher; no power supply required. Can be used as an audio source for computer, mixer, sound card, wireless microphone, or wired microphone signal switching, as well as talkback switching. Quickly re-route your microphone signal: connect output A to the stage sound reinforcement system and output B to the internal communication bus. Zero latency, studio-grade balanced XLR output jack for lossless, seamless switching. Note: Since condenser microphones require 48V phantom power, a loud pop may occur when switching.
