## Description

ParameterChip: TPA3116D2 (With AM interference supperession)Bluetooth Version: 5.0 (Without occlusion 15m)SNR: ＞90 dBAudio Input: AUX + BluetoothChannel: 2.0 StereoAdaption Supply Voltage: 9-27V / 2A aboveSpeaker: 15-100W, 4-8OhmOutput Power:15W*212V, 8Ω30W*2 12V, 4Ω20W*2 19V, 8Ω40W*2 19V, 4Ω30W*2 24V, 8Ω50W*2 24V, 4ΩProtection Mechanism: overheating, undervoltage, overheating, DC detection, short circuit protectionTip: To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound power. Please ensure that the power of the adaptor is greater than the actual working power of the amplifier.Package Including1 * Amplifier board bluetooth 5.01 * Shell (upper+lower)Accessories as shown

## Features

- [HIFI & Stereo] High quality dual channel 50W*2 power amplifier board for HIFI music. With AUX and Bluetooth two audio input methods, 2-in-1. 5.0 Bluetooth version, the transmission efficiency is higher, the transmission distance is farther. With a filter inductor, the sound is round and clear
