• ZK-MT21 2x50W+100W 2 Channel Subwoofer Digital Power Amplifier Board AUX 12V 24V Audio Stereo Bluetooth-compatible 5 Bass Amp for Home Theater Speaker Feature: The Bluetooth-compatible audio power amplifier module has 2 channels and the utmost output power is 2X50W+100W It has two audio enter modes, AUX and Bluetooth-compatible, and a two-in-one energy amplifier board Bluetooth-compatible5, increased transmission efficiency, longer transmission distance It has short-circuit protection, over-current, over-heating, and anti-reverse defense to forestall complete failure When an overload occurs, the gadget experiences the fault situation to the processor to protect itself from harm It adopts copper DC connectors and barrier terminals It can withstand high current without heating or unfavourable wires Classic look multi-function main knob The main knob adopts a rotary encoder that is solely used in high-end strength amplifiers, which realizes 360-degree stepless tuning and a comfortable one-key delivery and stop The operation is easy and handy by means of long pressing the switch With bass, treble, subwoofer frequency and volume control, you would smoothly adjust the volume and revel in the tune tone you want It is widely utilized in shopping malls, domestic theaters, speakers, etc Specification: Product name: 2 channel Bluetooth-compatible audio energy amplifier module Product model: ZK-MT21 Bluetooth-compatible version: 5 (unobstructed, 15 meters) Input sensitivity: 500mV Input method: AUX+ Bluetooth-compatible Number of channels: 2 channels Power amplifier chip: Domestic energy amplifier chip Adapter strength supply: above DC12-24V/5A (24V battery pack isn't allowed) Adapted speakers: 20-100W, 4-8Q Output power: left and appropriate channels <50W; subwoofer <100W Protection mechanism: Anti-reverse connection, overheating, overcurrent, quick circuit defense Product size: 93mm*90mm*22mm Product weight: about 130g Notice: The product would be related with an exterior antenna, yet doesn't consist of an antenna and an antenna base, please purchase it individually Tip: Only when the audio input is enough and the ability delivery voltage/current is enough, there'll be ample output power!!! The higher the power supply voltage, the bigger the output power, and the smaller the speaker impedance, the larger the output power!!! Please ensure that the power of the adapted power supply is greater than the actual operating strength of the amplifier!!! Note: Due to the several monitor and lightweight effect, the particular color of the article might be barely various from the colour showed on the photos Thank you! Please enable 1-2cm measuring deviation because of manual dimension 1 X Power Amplifier Board 1 X Accessory Pack
