SAMP-200 HIFI Dual Core TPA3255 Stereo Ampലൈഫ് ബോർഡ്

1. ആമുഖം

എസ്AMP-200 is a high-performance Class D power amplifier board designed for true high-end sound quality. It features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath Ultra HD) to maintain ultra-low distortion across the entire audio frequency band. This amplifier board operates in AD mode, offering significant power output and high efficiency with ultra-low idle losses.

2 പ്രധാന സവിശേഷതകൾ

• Utilizes two American TI-TPA3255 power amplifier modules for superior output power separation.
• Front-end differential input circuit with boost technology for enhanced dynamic range.
• Fully shielded, low-loss sealed inductors and imported filter capacitors ensure stable performance.
• Operates in AD mode with Class D efficiency.
• Unique 2 VRMS analog input interface for seamless connection with high-performance DACs (e.g., TI's PCM5242).
• High power efficiency with ultra-low power level idle losses (less than 2.5W).

5. സജ്ജീകരണ നിർദ്ദേശങ്ങൾ

Careful connection is essential for proper operation and to prevent damage to the amplifier board and connected equipment. Ensure all connections are secure before applying power.

5.1 പവർ സപ്ലൈ കണക്ഷൻ

Connect a DC power supply within the range of 19V to 52V to the designated power input terminals on the board. Observe correct polarity (positive and negative). The terminals are typically labeled 'DC 19V-50V' or similar.

5.2 ഓഡിയോ ഇൻപുട്ട് കണക്ഷൻ

Connect your audio source (e.g., DAC, preamplifier) to the 2 VRMS analog input interface. The input terminals are typically labeled 'INPUT L', 'G' (Ground), and 'R'. Use appropriate shielded audio cables to minimize noise.

5.3 Speaker Output Connection

Connect your passive speakers to the output terminals. Ensure correct polarity for each channel (Left+ L-, Right+ R-). The board supports speaker impedances of 2, 4, or 8 ohms. Verify your speakers' impedance matches the ampലൈഫയറുടെ കഴിവുകൾ.

6. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

Once all connections are made, you can begin operating the amplifier board:

1. പവർ ഓൺ: Connect the power supply to a wall outlet. The amplifier board should power on, indicated by any onboard LEDs (if present).
2. ഓഡിയോ പ്ലേബാക്ക്: നിങ്ങളുടെ ബന്ധിപ്പിച്ച ഉറവിടത്തിൽ നിന്ന് ഓഡിയോ പ്ലേ ചെയ്യാൻ ആരംഭിക്കുക.
3. വോളിയം നിയന്ത്രണം: Adjust the volume using your audio source or any external preamplifier connected to the input. This amplifier board does not have onboard volume control.
4. പവർ ഓഫ്: Disconnect the power supply from the wall outlet to power off the ampലൈഫ് ബോർഡ്.

7. പരിപാലനം

നിങ്ങളുടെ ദീർഘായുസ്സും ഒപ്റ്റിമൽ പ്രകടനവും ഉറപ്പാക്കാൻ amplifier board, follow these maintenance guidelines:

• വൃത്തിയായി സൂക്ഷിക്കു: Regularly clean the board with a soft, dry cloth. Avoid using liquids or abrasive cleaners.
• ഈർപ്പം ഒഴിവാക്കുക: സൂക്ഷിക്കുക amplifier board away from water, humidity, and other liquids.
• Prevent Static Discharge: Handle the board with care, especially when installing or removing, to avoid electrostatic discharge (ESD) which can damage components.
• വെന്റിലേഷൻ ഉറപ്പാക്കുക: The heatsink is crucial for dissipating heat. Ensure it is not obstructed and that there is adequate airflow around the board, especially during prolonged operation at high power.
• സംഭരണം: When not in use for extended periods, store the board in a dry, dust-free environment.

8. പ്രശ്‌നപരിഹാരം

നിങ്ങളുടെ S-ൽ പ്രശ്നങ്ങൾ നേരിടുകയാണെങ്കിൽAMP-200 amplifier board, refer to the following common problems and solutions:

8.1 ശബ്ദ ഔട്ട്പുട്ട് ഇല്ല

• പവർ പരിശോധിക്കുക: പവർ സപ്ലൈ ശരിയായി ബന്ധിപ്പിച്ചിട്ടുണ്ടെന്നും നിർദ്ദിഷ്ട വോളിയം നൽകുന്നുണ്ടെന്നും ഉറപ്പാക്കുക.tage (19V-52V DC).
• Check Audio Input: Verify that the audio source is connected correctly to the input terminals and is playing audio.
• Check Speaker Connections: Ensure speakers are properly connected to the output terminals with correct polarity.
• വോളിയം നില: Confirm that the volume on your audio source or preampലൈഫയർ മിനിമം ആയി സജ്ജീകരിച്ചിട്ടില്ല അല്ലെങ്കിൽ മ്യൂട്ട് ചെയ്തിട്ടില്ല.

8.2 വികലമായ ശബ്ദം

• ഇൻപുട്ട് ലെവൽ: Reduce the input signal level from your audio source. An excessively high input signal can cause distortion.
• വൈദ്യുതി വിതരണം: Ensure the power supply is stable and can provide sufficient current for the desired output level. Fluctuations or insufficient current can lead to distortion.
• സ്പീക്കർ ഇംപെഡൻസ്: Verify that your speakers' impedance is compatible with the amplifier (2, 4, or 8 ohms).

8.3 Low Output Power

• പവർ സപ്ലൈ വോളിയംtage: As noted in the specifications, lower input voltage will result in reduced output power. Ensure your power supply is providing adequate voltage, ideally closer to the upper limit (52V) for maximum output.
• സ്പീക്കർ ഇംപെഡൻസ്: Lower impedance speakers (e.g., 2 ohms) will draw more current and allow for higher power output compared to higher impedance speakers (e.g., 8 ohms) at the same voltage.

9 ഉപയോക്തൃ നുറുങ്ങുകൾ

• പവർ സപ്ലൈ സെലക്ഷൻ: For optimal performance and to achieve the advertised maximum output power, it is highly recommended to use a robust power supply capable of delivering up to 52V DC with sufficient current capacity (e.g., 20A or more). This will allow the amplifier to operate at its full potential.
• ചൂട് മാനേജ്മെൻ്റ്: While the board includes a heatsink, consider additional cooling solutions (e.g., a small fan) if operating at very high power levels for extended periods, especially if enclosed in a case.
