Conexión de alimentación
- Connect a DC power supply (18V-50V, >10A) to the VCC and GND terminals. Ensure correct polarity.
Conexión de entrada de audio
- Connect your audio source (e.g., decoder) to the XH2.54-3P audio socket (Line-in).
Conexións de altofalantes
The ZK-3002 supports both Stereo Dual Channel BTL Mode and Mono Single Channel PBTL Mode. Select the desired mode using Switch 1 on the board.
Figure 4: Detailed wiring diagrams for Stereo (BTL) and Mono (PBTL) configurations, showing speaker and power connections.
Stereo Dual Channel BTL Mode:
- Set Switch 1 to OFF (Stereo BTL Mode).
- Connect the left speaker to the L+ and L- terminals.
- Connect the right speaker to the R+ and R- terminals.
- Ensure speaker impedance is between 3ohm and 8ohm.
Mono Single Channel PBTL Mode:
- Set Switch 1 to ON (Mono PBTL Mode).
- Connect the mono speaker to the R+ and L- terminals (bridged output).
- Ensure speaker impedance is between 2ohm and 8ohm.
Instrucións de funcionamento
Encendido/apagado
- 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.
Control de volume
- Adjust the volume using the potentiometer labeled "Adjust Gain" on the board. Rotate clockwise to increase volume, counter-clockwise to decrease.
Control do ventilador
- The ZK-3002 features an intelligent temperature-controlled fan.
- Use Switch 2 to control the fan's operation:
- ACTIVADO: 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:
- ACTIVADO: 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.
Mantemento
- Limpeza: 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.
- Ventilación: Asegurar o amplifier board is placed in a well-ventilated area to prevent overheating. Do not obstruct the fan or heatsink.
- Almacenamento: When not in use for extended periods, store the board in a dry, dust-free environment.
Resolución de problemas
| Problema | Causa posible | Solución |
|---|---|---|
| Sen saída de son | Alimentación incorrecta voltage/current; Loose speaker connections; Incorrect audio input connection; Amplifier en modo de protección. | Verify power supply meets 18V-50V and >10A requirements. Check all speaker and audio input wiring for secure connections and correct polarity. Power cycle the board to reset protection mode. |
| Son distorsionado | Input signal too strong; Speaker impedance mismatch; Faulty speaker. | Reduce the input audio signal level. Ensure speaker impedance matches the recommended range (3-8ohm for stereo, 2-8ohm for mono). Test with a different speaker. |
| Ampsobrequecemento do lifier | Poor ventilation; Fan not operating; Excessive load. | Ensure adequate airflow around the board. Check if the fan is spinning (set Switch 2 to OFF for manual control to test). Reduce output volume or speaker load. |
| O ventilador non xira | Fan control switch set to automatic (ON) and temperature is low; Fan malfunction. | Set Switch 2 to OFF (Manual Control) to force the fan on. If it still doesn't spin, the fan may be faulty. |
