The IR-250 is a professional infrared microphone system that includes a receiver unit, up to three infrared microphones, and a dedicated charger. The receiver operates from a DC12 V supply (0.5‑1 A) and can be powered by an AC‑DC adapter supporting 100‑240 V. Each microphone contains a rechargeable battery and can be used simultaneously (up to two microphones per receiver).
The manual explains how to install the optical sensor on the receiver, connect the microphones, switch between MIC and LINE outputs, and safely charge the batteries using the supplied DC5 V 2 A charger. It also provides troubleshooting steps for common issues such as no audio output, low battery indicators, and interference from strong infrared sources like TV screens. This manual is written in Japanese.
