The power supply is critical for performance. The higher the voltage, the higher the current and output power. It is generally recommended to use an 18V-24V power supply with a current above 5A. If the voltage is too low, the sound may distort at higher volumes.
Typically, 4 ohm or 8 ohm speakers are compatible. Ensure the speaker's power rating matches or exceeds the amplifier's output to prevent blowout. For a 100W amplifier, a 150W-250W speaker setup is ideal to avoid clipping.
Power on the module, search for 'Wuzhi Audio' in your device's Bluetooth settings, and connect. A successful connection is usually indicated by a solid blue LED or an audio prompt.
Distortion at high volumes typically means the input power is insufficient. Replace the power adapter with one that has a higher voltage and current rating to meet the amplifier's demands.
Power on two ZK-1001U boards, then triple-press the volume knob on one board. The blue TWS indicator will flash, and the second board will connect automatically to form a left/right stereo setup.
