Treble Bass Adjustment:</strong> The left and right channel high/low tones can be adjusted using the BASS and TREBLE knobs. The BASS knob controls the low frequency, with clockwise rotation increasing the bass and counterclockwise rotation reducing the bass. The TREBLE knob controls the high frequency, with clockwise rotation increasing the treble and counterclockwise rotation reducing the treble.<br /> <strong>2. TDA7498E Chip:</strong> 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 multiple protection measures such as overheat protection, undervoltage protection, and short-circuit protection to prevent system damage and failure.<br /> <strong>3. Bluetooth-compatible 5. 0 Amplifier:</strong> With a transmission distance of up to 15 meters (unobstructed), this amplifier supports 2.0-channel stereo output, with 150W*2 (left and right channel) pure HIFI audiophile sound quality. The high frequencies are crisp and clear, the middle-range is gentle and delicate, and the bass is powerful and impactful. The main knob uses a high-end amplifier's rotary encoder, 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-button start/stop function.<br /> <strong>4. Audio Inputs:</strong> 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.<br /> <strong>5. Cooling Mechanism:</strong> 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 dissipation of the shell. This doubles the heat dissipation 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 passive and active speakers.<br /><br/><br/><span style="color:black;font-family:inherit;font-size:12px;"><strong>Specification:</strong></span><br /> <span style="color:black;font-family:inherit;font-size:12px;">Product model: YS-XPSM<br /> Bluetooth-compatible version: 5.0 (unobstructed, 15 meters)<br /> Input method: AUX+Bluetooth-compatible<br /> Number of channels: 2.0 channels (left channel+right channel)<br /> Adapted power supply: DC12~32V (undervoltage protection below 9V, can also support 12V power supply)<br /> Adapted speaker: 30-200w, 4-8 ohms<br /> Output power: left and right channels ≤ 150W<br /> Protection mechanism: anti reverse connection, undervoltage, overheating, overcurrent, short circuit protection<br /> Product size: 119x70x21mm/4.68x2.75x0.82inch<br /> Product weight: net weight 135g<br /> <br /> Reminder:<br /> Only when the audio signal input is large enough and the power supply voltage/current is large enough can there be sufficient output power!<br /> The higher the power supply voltage, the greater the output power, the smaller the horn impedance, and the greater the output power!<br /> Please ensure that the power of the adapter power supply is greater than the actual working power of the amplifier!<br /> <br /> How to choose a speaker?<br /> Regarding the type of speaker: Commonly used speakers are generally 4-8 ohms, and can be used with left and right channel 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 burning 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.<br /> <br /> How to adjust the total volume?<br /> The VOL knob adjusts the total volume. The total volume of right-handed rotation increases, while the total volume of left-handed rotation decreases.<br /> <br /> How to adjust the high and low frequencies of the left and right channels?<br /> The BASS knob is used to control the bass, with right hand bass enhanced and left hand bass attenuated. When the knob is in the middle position, there is no increase or decrease in bass. The TREBLE knob controls the treble, with the right treble enhanced and the left treble attenuated. When the knob is in the middle position, there is no increase or decrease in treble.<br /> Attention: Adjusting the treble and total volume to maximum simultaneously can easily cause amplifier protection and sound jamming. Turn down the treble or turn the volume knob on the right to the left to reduce the total volume.</span><span style="color:black;font-family:inherit;font-size:12px;"></span><br /> <br /> <p style="color:black;font-family:inherit;font-size:12px;"> <strong>Note:</strong><br /> 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.
