ZK-MT21 100W+2*50W 2.1 Subwoofer Dial Power Amplifier Board AUX 12/24V Audio Stereo Bluetooth 5.0 Amp For Home

YS-XPSM Audio Power Amplifier Board Module 150Wx2 TDA7498E Ba Adjustment Power Amplifier Board Bluetooth-compatible 5.0 Dual Heat SinkFeature:1. Ba Adjustment:The left and right high/low tones can be adjusted using the B and knobs. The B knob controls the low frequency, with clockwise rotation increasing the ba and counterclockwise rotation reducing the ba. The knob controls the high frequency, with clockwise rotation increasing the and counterclockwise rotation reducing the .2. TDA7498E Chip:This chip supports high-fidelity audio amplification, with low distortion and noise levels, ensuring stable sound quality and clarity even at high output power levels. It also includes multe protection measures such as overheat protection, undervoltage protection, and short-circuit protection to prevent system damage and failure.3. Bluetooth-compatible 5.0 Amplifier:With a nsmiion distance of up to 15 meters (bstructed), this amplifier supports 2.0- stereo output, with 150W*2 (left and right ) pure audiophile sound quality. The high frequencies are crisp and clear, the middle-range is gentle and delicate, and the ba is powerful and impactful. The main knob uses a high-end amplifier's rotary , allowing for 360-degree infinite tone adjustment. It also includes high/low tone adjustment knobs and a volume/on-off knob, all with smooth operation and easy one-on start/stop function.4. Audio Inputs:The audio amplifier module features two types of audio inputs: Bluetooth-compatible input and AUX audio input. In Bluetooth-compatible mode, if an audio cable is inserted, it will automatically switch to audio input mode, with Bluetooth-compatible mode having the lowest priority.5. Cooling Mechanism:The module includes a large-area heat sink (463715mm) that is specially designed with thermal conductive silicon paste, which adheres closely to the copper-clad heat diipation of the shell. This doubles the heat diipation area, ensuring high-power and high-performance operation. The Bluetooth-compatible function can connect to smartphones, tablets, laptops, AUX devices such as MP3 players, and more. It can be connected to both paive and active speakers.Specification:Product model: YS-XPSMBluetooth-compatible version: 5.0 (bstructed, 15 meters)Input method: AUX+Bluetooth-compatibleNumber of s: 2.0 s (left +right )Adapted power supply: DC12~32V (undervoltage protection below 9V, can also support 12V power supply)Adapted speaker: 30-200w, 4-8 sOutput power: left and right s ≤ 150WProtection mechanism: anti re connection, undervoltage, overheating, overcurrent, short circuit protectionProduct size: 119x70x21mm/4.68x2.75x0.82inchProduct weight: net weight 135gReminder:Only when the audio signal input is large enough and the power supply voltage/current is large enough can there be sufficient output power!The higher the power supply voltage, the greater the output power, the smaller the horn impedance, and the greater the output power!Please ensure that the power of the adapter power supply is greater than the actual working power of the amplifier!How to choose a speaker?Regarding the type of speaker: Commonly used speakers are generally 4-8 s, and can be used with left and right speakers. Full frequency speakers or middle to high frequency speakers need to be connected, with a power range of 30W-200W. If your speaker has a low power, such as between 20W-50W, it can also be used. You need to reduce the power supply voltage to prevent ing the speaker when it is loud, such as choosing a power supply below 15V. The higher the selected voltage, the greater the sound or power that can be output. The speaker power should not exceed 200W, otherwise it will affect the sound quality.How to adjust the total volume?The VOL knob adjusts the total volume. The total volume of right-handed rotation increases, while the total volume of left-handed rotation decreases.How to adjust the high and low frequencies of the left and right s?The B knob is used to control the ba, with right hand ba enhanced and left hand ba attenuated. When the knob is in the middle position, there is no increase or decrease in ba. The knob controls the , with the right enhanced and the left attenuated. When the knob is in the middle position, there is no increase or decrease in .Attention: Adjusting the and total volume to maximum simultaneously can easily cause amplifier protection and sound jang. Turn down the or turn the volume knob on the right to the left to reduce the total volume.
