Description: ZK-MT21 2x50W+100W 2.1 Channel Subwoofer Digital Power Amplifier Board AUX 12V 24V Audio Stereo Bluetooth-compatible 5.0 Bass Amp for Home Theater Speaker Feature: The Bluetooth-compatible audio power amplifier module has 2.1 channels and the maximum output power is 2X50W+100W. It has two audio input modes, AUX and Bluetooth-compatible, and a two-in-one power amplifier board. Bluetooth-compatible5.0, higher transmission efficiency, longer transmission distance It has short-circuit protection, over-current, over-heating, and anti-reverse protection to prevent total failure. When an overload occurs, the device reports the fault condition to the processor to protect itself from damage It adopts copper DC connectors and barrier terminals. It can withstand high current without heating or damaging wires. Classic appearance multi-function main knob. The main knob adopts a rotary encoder that is only used in high-end power amplifiers, which realizes 360-degree stepless tuning and a smooth one-key start and stop. The operation is simple and convenient by long pressing the switch. With bass, treble, subwoofer frequency and volume control, you can easily adjust the volume and enjoy the music tone you want. It is widely used in shopping malls, home theaters, speakers, etc. Specification: Product name: 2.1 channel Bluetooth-compatible audio power amplifier module Product model: ZK-MT21 Bluetooth-compatible version: 5.0 (unobstructed, 15 meters) Input sensitivity: 500mV Input method: AUX+ Bluetooth-compatible Number of channels: 2.1 channels Power amplifier chip: Domestic power amplifier chip Adapter power supply: above DC12-24V/5A (24V battery pack is not allowed) Adapted speakers: 20-100W, 4-8Q Output power: left and right channels <50W; subwoofer <100W Protection mechanism: Anti-reverse connection, overheating, overcurrent, short circuit protection Product size: 93mm*90mm*22mm Product weight: about 130g Notice: The product can be connected with an external antenna, but does not include an antenna and an antenna base, please purchase it separately. Tip: Only when the audio input is enough and the power supply voltage/current is enough, there will be enough output power!!! The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power!!! Please make sure that the power of the adapted power supply is greater than the actual working power of the amplifier!!! Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement.

Connect the Bluetooth-compatible board card to the computer with the data line, open the APP, and click "Sound card" to switch the switch is completed with prompt sound playing. Turn on the computer player software to play music. Use 5.5/2.1 socket, compatible 5.5/2.1, 5.5/2.5 plug with DC adapter, convenient connection of non-standard plug. High quality full copper DC plug, long life Specification: Model: XY-C50L Power supply voltage: DC: 8~24V(the higher the voltage, the greater the output power) Bluetooth-compatible version: 5.0 Transmission distance: 15 m (no shielding) Number of channels: left and right double channels (stereo) Adapter horn: 0W~200W 4 ohm 8 ohm 16 ohm Protection mechanism: power reverse connection protection, short circuit protection, self-recovery overheating protection Complimentary cool features: mobile APP control; Supports for Android/iOS 12V-8 Ohms /15W+15W, 4 Ohm /20W+20W 15V-8 ohms /18W+18W, 4 ohms/greater than 30W+30W 19V-8 Ohms /32W+32W, 4 Ohms/greater than 45W+45W 24V-8 Ohms /40W+40W, 4 Ohms/greater than 50W+50W Size: 53x52x16mm/2.1X2X0.63in Weight: 60g Speaker selection: This product can continuously output 50W*2 power amplifier, 10W~200W speakers can be pushed, 8 ohms or 4 ohms speaker is recommended. If the power is within 50W of the speaker, the appropriate lower power supply voltage (such as 12V power supply) or turn down the playback volume; More than 50W horn power supply voltage is better (26V less). If music speakers appear "hiccup" phenomenon, the first consideration is insufficient power supply, use a larger power supply; Second, consider the power amplifier overheat protection, strengthen the heat dissipation or turn down the playback volume. Note: The output power of the power supply should be greater than the output power of the amplifier, otherwise it will affect the sound quality Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Packages: 1 X Power Amplifier Board 1 X Accessory Pack 1 Set x Amplifier Board
