Very simple small device with 1 input and two outputs, using a button switch to select which output receives the input signal. 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 non-common ground design. Simple and intuitive condenser/dynamic microphone signal switcher; no power supply required. Can be used with audio sources such as computer, mixer, sound card, wireless microphone, or wired microphone for signal switching or talkback applications. 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 jacks enable lossless switching between outputs. Simple and fast operation. Note: Condenser microphones require 48V phantom power; slight pop may occur when switching due to power impact.
