Douk Audio ☆ Douk Audio MC103-Pro 1-IN-3-OUT XLR Audio Selector I purchased this new but haven't used it much. In good condition. Thank you. The MC103-Pro is a 3-way passive stereo audio splitter. It supports one stereo XLR input and three outputs. You can freely select according to your audio equipment. The MC103 is designed for customers who have multiple music devices with XLR balanced outputs. It's convenient for comparing the performance of amplifiers using one audio source and three amplifiers. All-aluminum shell effectively avoids external noise and ensures high-quality signal transmission. Gold-plated XLR ports ensure reliable electrical connections and minimize signal attenuation during transmission. Each channel is connected with shielded wire to prevent external interference and achieve lossless signal transmission. Mini size and exquisite appearance. You can easily place and carry it, and enjoy the charm of music anywhere. Passive audio switcher, does not affect sound quality. Silver-plated contacts make the knob very smooth.
