[COD] ZK-MT21 Bluetooth 5.0 Amplifier 2.1Channel Subwoofer 50w*2+100w HighPower Audio Amplifie Smartphone Protection

Bluetooth version: 5.0 (15m unobstructed)

Audio input: AUX + Bluetooth

Channel: 2.1

Input sensitivity: 500mV

Adapted power supply voltage: 12-24V/5A or more (do not connect 24V battery pack)

Speaker: 20-100W, 4-8Ω

Tip: If the audio input is sufficient and the power supply voltage/current is sufficient, there is enough output power. The higher the power supply voltage, the greater the relative power. The output power of speakers with different impedances is also different. In the case of sufficient voltage and current, the greater the ohm of the speaker, the smaller the relative sound power. Please make sure that the power of the adapter is greater than the actual working power of the amplifier.

[2 in 1] High-quality power amplifier board. It has two audio input modes, AUX and Bluetooth, two in one. 5.0 Bluetooth version, higher transmission efficiency, longer transmission distance

[High performance] Bluetooth audio power amplifier module with 2.1 channels, the maximum output power is 2X50W+100W. With antenna and antenna base, the signal is better, the efficiency is high, and the anti-interference ability is strong

[Protection mechanism] It has short-circuit protection, over-current, over-heat, and anti-reverse protection to prevent complete failure. When an overload occurs, the device reports the fault to the processor to protect itself from damage

[High Quality] Use copper DC connectors and barrier terminals. It can withstand high current without heating or damaging wires. No DC head lead, compatible with the input power interface of this product, even if you don’t have a DC head adapter or battery, you can easily wire it
