SAMP-200 HIFI Dual Core TPA3255 Stereo Ampمجلس lifier

1. المقدمة

أما مؤشر ال 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. الميزات الرئيسية

• 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. المواصفات

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. تعليمات الإعداد

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 توصيل التيار الكهربائي

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 توصيل مدخل الصوت

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 توصيل مخرج مكبر الصوت

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 ampقدرات لايفير.

6. تعليمات التشغيل

Once all connections are made, you can begin operating the ampلوحة مكبر الصوت:

1. تشغيل الطاقة: Connect the power supply to a wall outlet. The amplifier board should power on, indicated by any onboard LEDs (if present).
2. تشغيل الصوت: ابدأ تشغيل الصوت من المصدر المتصل.
3. التحكم في مستوى الصوت: 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. إيقاف التشغيل: Disconnect the power supply from the wall outlet to power off the ampمجلس lifier.

7. الصيانة

لضمان طول العمر والأداء الأمثل لجهازك amplifier board, follow these maintenance guidelines:

• حافظ على نظافة: Regularly clean the board with a soft, dry cloth. Avoid using liquids or abrasive cleaners.
• تجنب الرطوبة: احفظ 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.
• ضمان التهوية: 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.
• تخزين: When not in use for extended periods, store the board in a dry, dust-free environment.

8. استكشاف الأخطاء وإصلاحها

إذا واجهت مشاكل مع جهازك SAMP-200 amplifier board, refer to the following common problems and solutions:

8.1 لا يوجد إخراج صوت

• التحقق من الطاقة: تأكد من توصيل مصدر الطاقة بشكل صحيح وتوفير مستوى الصوت المحددtage (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.
• مستوى الصوت: Confirm that the volume on your audio source or preampلم يتم ضبط مستوى الصوت على الحد الأدنى أو كتمه.

8.2 الصوت المشوه

• مستوى الإدخال: Reduce the input signal level from your audio source. An excessively high input signal can cause distortion.
• مزود الطاقة: Ensure the power supply is stable and can provide sufficient current for the desired output level. Fluctuations or insufficient current can lead to distortion.
• معاوقة مكبر الصوت: Verify that your speakers' impedance is compatible with the amplifier (2, 4, or 8 ohms).

8.3 طاقة خرج منخفضة

• حجم امدادات الطاقةtage: 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.
• معاوقة مكبر الصوت: 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 نصائح المستخدم

• اختيار مصدر الطاقة: 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.
• إدارة الحرارة: 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.
