R&L CHANNEL-BASS: Adjusts bass level for the left and right channels. R&L CHANNEL-TREBLE: Adjusts treble level for the left and right channels. SUBWOOFER-VOLUME: Controls the subwoofer volume. SUBWOOFER-FREQ: Adjusts the subwoofer cutoff frequency from approximately 20Hz to 200Hz. 🔊 Speaker Selection Left and right channels can be connected to 4Ω–8Ω full-range or mid/high-frequency speakers. Recommended speaker power is 20W–100W. The subwoofer output should be connected to a suitable subwoofer speaker, not a regular full-range speaker. The subwoofer should have suitable low-frequency performance, with the source information recommending a frequency capability of at least 50Hz. Speaker impedance and power should be matched correctly with the amplifier. 🔌 Power Supply Selection The power supply is important for achieving proper amplifier performance and sound quality. A power supply with excessive ripple may increase background noise. Recommended supply: 18V / 19V / 24V with current above 5A Lower-voltage or lower-current supplies can be used, but available output power will be reduced. Insufficient supply current can cause voltage drop, abnormal operation or poor sound quality. If the amplifier is operated near maximum volume, an inadequate power supply may result in distortion. The power supply should have sufficient capacity for the actual amplifier load. Higher supply voltage can provide greater available output power within the module's specified operating range. 📱 Bluetooth & AUX Input The ZK-MT21 provides two audio input methods: Bluetooth Bluetooth 5.0 wireless audio input Bluetooth is the preferred input mode according to the supplied product information. Bluetooth supports automatic reconnection. Once Bluetooth is successfully connected, the module operates in Bluetooth mode. AUX Connect an external audio source through the AUX input. When using AUX, ensure the Bluetooth connection has been disconnected if necessary. 🔧 Applications DIY Bluetooth speakers 2.1 channel speaker systems Home audio projects Portable audio systems Subwoofer amplifier projects Custom speaker cabinets Desktop speaker systems Multimedia speaker systems Electronics and audio DIY projects Replacement/custom amplifier systems 🛠️ Installation & Usage Connect a suitable DC 12–24V power supply to the amplifier module. Connect the left and right speakers to their respective output terminals. Connect a suitable subwoofer to the subwoofer output. Ensure the speaker impedance is within the supported 4–8Ω range. Connect the audio source through Bluetooth or AUX. Adjust the main volume, bass, treble, subwoofer volume and frequency according to your requirements. Start with a low volume and gradually increase it. Ensure adequate ventilation and heat dissipation during high-power operation. ⚠️ Important Precautions Do not connect directly to a 24V battery pack. Use a suitable regulated DC power supply. Do not reverse the power supply polarity. Do not short-circuit the speaker outputs. Do not exceed the recommended speaker power and impedance. Ensure the power supply can provide sufficient current. Insufficient power may cause distortion or abnormal operation. Excessive load can cause the amplifier to heat up and activate thermal protection. Provide adequate ventilation during high-power operation. If distortion occurs at high volume, reduce the volume or use a more suitable power supply. The amplifier's actual output depends on the power supply, speaker impedance, audio input and overall system configuration. 📦 Package Includes 1 × ZK-MT21 Bluetooth 5.0 2.1 Channel Audio Amplifier Module

Water Cooling Head Water Cooling Plate 40*40mm
[Aluminium Heat Sink] Liquid coolers excel at delivering cooling to concentrated heat sources such as Peltier Elements and for delivering cooled fluid into remote or compact locations where the cooling assembly itself cannot be located. The basic operation is simple: fluid flows in one tube, it is cooled, and then it flows out the other tube. An external pump is required, and typically small DC magnetic-drive pumps are used to minimize the amount of pump power (heat) that is imparted to the fluid. Applications: Computer CPU water, industrial inverter driver, laser head cooling, industrial control cabinet cooling. Features: Heavy Aluminium build Internal flow channel extrusion forming Applicable to computer CPU water, industrial inverter driver, laser head cooling, industrial control cabinet cooling Package Includes: 1 x Water Cooling Head Water Cooling Plate 40*40mm
