AIYIMA A03(7555円)より圧倒的にオススメ！アリエク 755円 2.1chアンプ紹介(前編)

I'd like to introduce the items I ordered from AliExpress. My previous Amazon purchase failed. [AIYIMA A03] https://amzn.asia/d/3Ggjvzs A mere 1/10th the price of ¥7,555. 2.1ch (passive woofer driver capable) Bluetooth-enabled power amplifier [ZK-MT21] Price on AliExpress is ¥755! Uses CS8673E IC I highly recommend this! The CS8673E has an operating voltage of 5V to 24V. I can't read Chinese, but according to the datasheet: Output Power @ Single Channel PO at 10% THD+N, VDD=18V@RL=4Ω 47W PO at 10% THD+N, VDD=21V@RL=4Ω 64W PO at 10% THD+N, VDD=24V@RL=4Ω 82W Output Power @ Stereo Audio PO at 10% THD+N, VDD=16V@RL=4Ω 2x33W PO at 10% THD+N, VDD=21V@RL=8Ω 2x33W PO at 10% THD+N, VDD=24V@RL=8Ω 2x42W 24V mono, 82W @ 4Ω 24V stereo, 42W x 2 @ 4Ω This is a great amp! There's also the ZK-TB21, which uses the same IC (TPA3116D2) as the AIYIMA A03 but with a different model number. (I don't own it.)
