4.1. പവർ ഓൺ/ഓഫ്

  • Connect the power supply as described in Section 3.3.
  • The green RUN LED indicator will turn ON when powered.
  • The red ERROR LED indicator will turn ON if there is a hardware connection problem or firmware mismatch.

4.2. ബ്ലൂടൂത്ത് പ്രവർത്തനം

  • When Bluetooth is searching for a device, the Bluetooth LED (LED1) will blink.
  • Once paired, the Bluetooth LED (LED1) will remain ON.
  • To cancel pairing, press the button connected to J2.

4.3. Line Input Operation

  • Connect your audio source to the 3.5mm line input (J13).
  • If both Bluetooth and line input are active, their signals will be mixed.

4.4. Signal Level Sensor System

The JAB4 features a signal level sensor system for power efficiency:

  • If no audio signal is detected for 5 minutes, the amplifier will automatically enter standby mode.
  • When an audio signal is detected again, the ampലൈഫയർ സാധാരണ പ്രവർത്തനം പുനരാരംഭിക്കും.
  • The Signal Detection LED (LED2) will be ON when a signal is detected and OFF when no signal is detected for 5 minutes.

4.5. Using External Potentiometers

The functions of the potentiometers (POT1-POT4) automatically adjust based on the selected output mode (4.0/2.1/2.0). Refer to the JAB4 Datasheet for specific functions in each mode.

4.6. DSP Programming and PC UI Control

To utilize the full capabilities of the ADAU1701 DSP, you will need a WONDOM ICP programmer (e.g., ICP5).

  • SigmaStudio Programming: Allows for custom audio processing designs.
  • PC UI Control: Provides real-time adjustment of parameters like gain, volume, filters, and EQ via a graphical interface.

For detailed steps on programming and PC UI control, please refer to the dedicated ICP5 user guides:

5. പരിപാലനം

  • Keep the board clean and free from dust. Use a soft, dry cloth for cleaning.
  • Avoid exposing the board to moisture or extreme temperatures.
  • Ensure proper ventilation when operating to prevent overheating.
  • Do not attempt to modify the board unless you are an experienced electronics professional, as this may void the warranty and cause damage.

6. പ്രശ്‌നപരിഹാരം

പൊതുവായ പ്രശ്നങ്ങളും പരിഹാരങ്ങളും
പ്രശ്നംപരിഹാരം
JAB4 not recognized by PC (when using ICP5)
  • Ensure ICP5 firmware is updated.
  • Use a good quality USB Type-C cable that supports data communication.
  • Ensure ICP5 is not connected to the JAB4 board when first connecting ICP5 to the PC.
  • Install the correct USB driver for ICP5 (compatible with Win 7, 10, 11).
Cannot write program to JAB4 (when using ICP5)
  • Ensure ICP5 is recognized by the PC.
  • Set SW1 on ICP5 to 'USBi' and SW4 to 'IIC' (for ADAU1701 DSP).
  • Verify SigmaStudio shows 'Active: Downloaded'.
Target device not working normally (no sound) when connected with ICP5
  • Check all connection steps and input/output cables.
  • Disconnect ICP5 and re-power the JAB4 board.
ശബ്ദ ഔട്ട്പുട്ട് ഇല്ല
  • വൈദ്യുതി വിതരണവും കണക്ഷനുകളും പരിശോധിക്കുക.
  • Verify speaker wiring for correct output mode.
  • Ensure audio input source is active and volume is up.
  • Check if the signal level sensor has put the ampസ്റ്റാൻഡ്ബൈ മോഡിലേക്ക് ലൈഫയർ.
ബ്ലൂടൂത്ത് കണക്ഷൻ പ്രശ്നങ്ങൾ
  • Ensure the JAB4 is in pairing mode (Bluetooth LED blinking).
  • Try cancelling existing pairings using the J2 button.
  • Check for interference or distance from the source device.
  • Consider using an external Bluetooth antenna for better range/stability.

7 ഉപയോക്തൃ നുറുങ്ങുകൾ

  • DSP നിയന്ത്രണം: To adjust crossover settings, volume, or EQ, you must use a WONDOM ICP programmer (like ICP5) connected to a laptop with SigmaStudio or the dedicated PC UI software. Direct connection to a laptop without the ICP programmer will not allow DSP control.
  • ഫേംവെയർ അപ്‌ഡേറ്റുകൾ: Always ensure your ICP programmer has the latest firmware for compatibility with your JAB4 board and other WONDOM DSP products.
  • Initial Setup Volume: When setting up or adjusting parameters via PC UI, it's recommended to set the volume to a minimum level to avoid unexpected loud sounds or speaker damage.
  • Output Mode Switching: Always power off the JAB4 board before changing speaker wiring to switch between 4.0, 2.1, or 2.0 output modes. This prevents the amplifier from entering protection mode or being damaged.
