SAMP-200 HIFI Dual Core TPA3255 Estèreo AmpJunta més viva

1. Introducció

El SAMP-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. Característiques clau

• 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).

3. Especificacions

Note: The power test results are measured at a 50V power supply. Using a lower voltage power supply (e.g., 24V or 36V) will result in reduced output power.

5. Instruccions de configuració

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 Connexió a la font d'alimentació

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 Connexió d'entrada d'àudio

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 ampcapacitats del lificador.

6. Instruccions de funcionament

Once all connections are made, you can begin operating the amptauler de vidació:

1. Encès: Connect the power supply to a wall outlet. The amplifier board should power on, indicated by any onboard LEDs (if present).
2. Reproducció d'àudio: Comença a reproduir àudio des de la font connectada.
3. Control de volum: 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. Apagar: Disconnect the power supply from the wall outlet to power off the amptauler més viu.

7. Manteniment

Per garantir la longevitat i el rendiment òptim del vostre ampplaca del lificador, seguiu aquestes pautes de manteniment:

• Mantenir net: Regularly clean the board with a soft, dry cloth. Avoid using liquids or abrasive cleaners.
• Eviteu la humitat: Mantenir el 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.
• Assegureu-vos de la ventilació: 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.
• Emmagatzematge: When not in use for extended periods, store the board in a dry, dust-free environment.

8. Solució De Problemes

Si teniu problemes amb el vostre SAMP-200 ampplaca del lifer, consulteu els següents problemes i solucions habituals:

8.1 Sense sortida de so

• Comproveu la potència: Ensure the power supply is correctly connected and providing the specified voltage (19V-52V CC).
• Check Audio Input: Verify that the audio source is connected correctly to the input terminals and is playing audio.
• Comproveu les connexions dels altaveus: Ensure speakers are properly connected to the output terminals with correct polarity.
• Nivell de volum: Confirm that the volume on your audio source or preamplifier is not set to minimum or muted.

8.2 So distorsionat

• Nivell d'entrada: Reduce the input signal level from your audio source. An excessively high input signal can cause distortion.
• Font d'alimentació: Ensure the power supply is stable and can provide sufficient current for the desired output level. Fluctuations or insufficient current can lead to distortion.
• Impedància de l'altaveu: Verify that your speakers' impedance is compatible with the amplifier (2, 4, or 8 ohms).

8.3 Low Output Power

• Alimentació Voltage: 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.
• Impedància de l'altaveu: 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. Consells d'usuari

• Selecció de la font d'alimentació: 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.
• Gestió de la calor: 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.
