പ്രവർത്തന നിർദ്ദേശങ്ങൾ
നിലവിലെ ക്രമീകരണം
It is recommended to adjust the quiescent current for optimal Class A operation. The default setting is 1.2A at 24V.
- Set a universal multimeter to measure current (10-20A range).
- Disconnect the VCC line ശക്തിയിൽ നിന്ന് ampലൈഫ് ബോർഡ്.
- Connect the red probe of the multimeter to the VCC terminal of the rectifier board.
- Connect the black probe of the multimeter to the VCC terminal of the power amplifier board. This completes the circuit through the multimeter, allowing current measurement.
- Adjust the potentiometer labeled KT2 (W202) on the board to achieve the desired current. A setting of 1.2A is recommended.
- പ്രധാന കുറിപ്പ്: The measurement points for current and midpoint voltage are different. Ensure you change the red probe's connection point when switching between current and midpoint voltagഇ അളവുകൾ.

മെയിൻ്റനൻസ്
To ensure the longevity and stable performance of your amplifier boards, consider the following maintenance guidelines:
- വെൻ്റിലേഷൻ: ചുറ്റും മതിയായ വായുസഞ്ചാരം ഉറപ്പാക്കുക amplifier boards, especially given that Class A amplifiers generate significant heat. Do not obstruct the heatsinks.
- ശുചിത്വം: Periodically inspect the boards for dust accumulation. Use a soft brush or compressed air to gently remove dust from components and heatsinks.
- കണക്ഷനുകൾ: Regularly check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent performance or damage.
- പരിസ്ഥിതി വ്യവസ്ഥകൾ: പ്രവർത്തിപ്പിക്കുക amplifier in a dry environment, away from excessive humidity, direct sunlight, and extreme temperatures.

നിങ്ങളുടെ ഉപകരണത്തിൽ പ്രശ്നങ്ങൾ നേരിടുകയാണെങ്കിൽ amplifier boards, review ഇനിപ്പറയുന്ന പൊതുവായ പ്രശ്നങ്ങളും പരിഹാരങ്ങളും:
- സൗണ്ട് ഔട്ട്പുട്ട് ഇല്ല:
- Verify all power connections are secure and the power supply is providing the correct voltage.
- Check speaker connections for proper polarity and secure contact.
- Ensure the audio input source is functioning correctly.
- വികലമായ ശബ്ദം:
- Check the input signal level; excessive input can cause distortion.
- Ensure speakers are correctly matched to the amplifier's output power and impedance.
- Verify the current adjustment (KT2/W202) is set correctly (e.g., 1.2A).
- അമിതമായ ചൂട്:
- ക്ലാസ് എ amplifiers naturally run hot. However, ensure adequate ventilation and heatsink clearance.
- Check the quiescent current setting; a higher current will generate more heat.
- High Frequency Ringing (>12kHz):
- Some users have reported that adding a 500pF capacitor in parallel with resistor R5 can help mitigate high-frequency ringing. This modification should only be performed by experienced individuals.
