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 Level Sensor] A float switch is a device used to sense the level of liquid within a tank, it may actuate a pump, an indicator, an alarm, or another device. A float switch is a device used to sense the level of liquid within a tank. The switch may actuate a pump, an indicator, an alarm, or another device. Use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating, pumps, ponds, basement alarms, boats, air condition drain pans, pressure washers, carpet cleaning machine, reef aquarium, fluid control, ice machines, coffee pots, marine, automotive, automobiles, tropical fish tanks, evaporator coils, condensation line, in relays, or whatever your project may be. It can be easily converted from normally open to normally close by inverting the float. Note: because the current that the switch can carry is much little(0.5A), you must use a relay or contactor when it is connected by a load, relay and contactor are not included here. Specifications:- Cable Length: 30.5(cm) Maximum Load: 50 W Max Switching Voltage: 100V DC Minimum Voltage: 250V DC Maximum Switching Current: 0.5 A Max Load Current: 1.0 A Max Contact Resistance: 0.4 ΩTemp Rating: -20~ 80 degree Applications:- Household Equipment such as overhead water tanks, Water purifiers. Use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating, or whatever your project may be. Up float switch Contains no mercury Product. How Magnetic Reed Liquid Level Sensors Work:- The purpose of a float switch is to open or close a circuit as the level of a liquid rises or falls. Most float switches are "normally closed," meaning the two wires coming from the top of the switch complete a circuit when the float is at its low point, resting on its bottom clip or stop (for example, when a tank is dry). Most float switches utilize a magnetic reed switch to open or close the circuit. The reed is encased in a glass tube, which is cemented into a plastic or stainless steel stem with epoxy. The illustration to the left demonstrates how a magnet can be used to open or close a circuit by moving it closer to or farther away from a reed switch. When the magnet comes close to the two contacts, they draw together and touch, allowing the current to pass through. When the magnet is moved away, the contacts demagnetize and separate, breaking the circuit. In a float switch, the magnetic reed switch is hermetically sealed in a stem, most often made from plastic or stainless steel. The float encases a sealed magnet, which moves up and down the length of the stem as a fluid level rises and falls. As the magnet passes by the contacts in the encased reed switch, they draw together and complete a circuit between the two lead wires. The operation shown can usually be reversed by removing the bottom clip from the switch, inverting the float, and replacing the clip. When this change is made, the switch circuit will be open when the float is resting on the bottom clip and closed when the float rises. Properly used, float switches can deliver millions of on/off cycles, for years of dependable operation. Failures are normally due to overloading, frequently caused by spiking voltage. Before designing a circuit that uses a float switch, be sure to read our Technical Page on Spiking Voltage & Float Switches. * Product Images are shown for illustrative purposes only and may differ from the actual products.
