Fosi Audio BT20A Pro TPA3255 Bluetooth Sound Power Amplifier 300W x2 Mini HiFi Stereo Class D Amp Bass Treble For Home Theater

Product Description

The Fosi Audio BT20A Pro is a way to improve the sound in your home. It is a very strong amplifier. This amplifier is made to work with speakers that need power. These speakers can be ones on the shelves, big ones on the floor, or even the ones on the desk. The BT20A Pro is inside a case made from aluminum. This case is made using a method called CNC machining. The amplifier uses a part from Texas Instruments called the TPA3255. This part helps make the sound clean and full of energy at all volume levels.

The BT20A Pro has a connection called Qualcomm Bluetooth 5.0. This lets you send music from your phone, tablet, computer, TV, or even a record player. You need a part for the record player, but it works well. You can change the sound by using the knobs on the front of the amplifier. These knobs let you adjust the bass and the treble. They also have a position that stops them from changing the sound.

Key Features

Texas Instruments TPA3255 High-Power Chip: This chip delivers up to 300 watts times 2 peak output power into 4-ohm loads at 48 volts. It drives speakers with very little harmonic distortion. The distortion is less than or equal to 0.005 percent.

Replaceable Op-Amps (DIP-8 Sockets): This device has sockets where operational amplifiers can be swapped. Sound customizers can replace the stock NE5532 chips with dual op-amps.
