Product descrtion:

All parts and components of this product are  products, unpretentious and pure in quality; the use of high-quality  parts not only guarantees safety and quality, but also has a long service life, and more antly, it is a strong guarantee that the actual performance can reach the design goals. The pursuit of quality is our consistent aim.

Feature:

1. Adopt  TPA3221, NE5532, QCC3034

2. Adopt 5.0 Bluetooth , support: APTX-HD/APTX/ACC/SBC, the signal is more stable.

3. The power filter capacitor adopts 5 470UF/25V electrolytic capacitors.

4. The special power discharge sense of the red and gray ring is adopted to ensure the sound is clear and powerful.

5. The way to connect to Bluetooth is the same as that of ordinary devices!

6. Input mode: analog and Bluetooth input function. When the two methods are input at the same time, the Bluetooth input is given priority. After the Bluetooth connection, The RCA input is automatically disconnected; when analog input is required, please turn off the Bluetooth function of the mobile phone to switch.

Lighting style: in RCA mode, the red light is always on, and the bluetooth connection model, the green is on.

When you choose Amplifier with DC32V 5A Power Adapter, recommend 100 RMS 4 speaker. When you choose Amplfiier with DC24V 4.5A Power Adapter, recommend 70-80W RMS 4 speaker. The rated power of the power amplifier must be greater than the rated power of the speaker, generally 1.5 times. If the power of the power amplifier is too large, it will cause the speaker to overload (that is, burning the voice ); but if the power of the speaker is too small, it will cause the power amplifier to overload. If the power amplifier works in an overload and overcurrent state for a long time, not only the power amplifier is easy to burn, and the sound quality of the speakers will also deteriorate. Because the power amplifier will automatically increase the output current to increase the output power when it reaches its load limit in order to push the speaker (the power amplifier is overloaded), the power will quickly heat up until it burns out.

Package included:

1* A05 amplifier board

1*Power adapter(option)
