届くのも速くアンプICも本物で商品に問題点はありませんでした。当方、改造目的の購入だったため基盤のランドが商品画像と異なり小さく残念…ミュートのパターンは切断できますがカップリングなどは外付けとなります

Producto en buen estado. Muy bien manufacturado. A pesar de ser un amplificador de solo 3 Watts de potencia su sonido es espectacular. No requiere ningún aditamento especial para su funcionamiento, solo conecte y disfrute.

Used with 2 6ohm 5W speakers, so they obviously don't push the speaker to their max. Really didn't need that in the application though, Bluetooth portable speaker setup doesn't need to bump all that hard.Easy to set up, super low noise, and works outside of recommended specs. Not to mention dirt cheap. Love 'em
