Upute za rad

Uključivanje/isključivanje

• After all connections are secure, connect the power supply to an AC outlet. The board will power on automatically.
• To power off, disconnect the power supply from the AC outlet.

Kontrola glasnoće

• Adjust the volume using the potentiometer labeled "Adjust Gain" on the board. Rotate clockwise to increase volume, counter-clockwise to decrease.

Kontrola ventilatora

• The ZK-3002 features an intelligent temperature-controlled fan.
• Use Switch 2 to control the fan's operation:
  • NA: Fan Automatic Control (fan activates based on temperature).
  • OFF: Fan Manual Control (fan runs continuously).

Mode Switching (Stereo/Mono)

• Use Switch 1 to select the desired output mode:
  • NA: Mono PBTL Mode (for single, high-power speaker).
  • OFF: Stereo BTL Mode (for two-channel stereo sound).
• Note: Always power off the board before changing the mode switch to prevent potential damage.

Održavanje

• Čišćenje: Regularly clean the board with a soft, dry cloth. Ensure no dust accumulates on the fan or heatsink to maintain efficient cooling. Do not use liquid cleaners.
• Ventilacija: Osigurajte amplifier board is placed in a well-ventilated area to prevent overheating. Do not obstruct the fan or heatsink.
• Skladištenje: When not in use for extended periods, store the board in a dry, dust-free environment.
