This is a US-market unit designed for 110-120V mains. To run it on India's 230V supply, use a suitable step-down transformer rated above the amplifier's power draw, and fit a Type D/M plug adapter or a replacement grounded cord. The included power adapter converts AC to the required DC voltage. ### How many speakers can I connect to this Fosi Audio BL20C amplifier? The BL20C is a 2.1 channel amplifier, meaning it can drive one pair of passive stereo speakers and one powered subwoofer. It is not designed for multi-channel surround sound setups or driving multiple pairs of passive speakers. ### What audio formats does the U-disk input on the BL20C support? The U-disk input supports popular audio formats including MP3, WMA, APE, FLAC, and WAV. Ensure your files are no larger than 100MB each and your U-disk is formatted correctly for optimal playback. ### Can I use the Fosi Audio BL20C with my existing home theater receiver? The BL20C functions as a standalone stereo amplifier or a dedicated 2.1 channel amp.
