Κωδικός e-Wireless: 1215.981

Using the original Yamaha digital power amplifier chip YDA138

• Operating voltage: DC 9-14v
• Output power: dual channel output 2X10W, 1XW under 4 ohm load
• Conversion efficiency: when the power supply is 12V, the negative cut is 8 ohms, and the output power is 10Wj, 88%
• Signal-to-noise ratio: 103DB when the power supply is 12V, the negative cut is 8 ohms, and the output power is 10Wj
• Headphone playback: AB type, output power: 50mWX2 (large output at power supply of 12V and headphone impedance: 32 ohms)

1>.Headphone playback: AB type, output power 50mWX2 (in the power supply 12V, the headphone impedance is 32 ohms when the output is large)1. Adopt the original Yamaha digital power amplifier chip YDA138, no sound source input state, even if the volume knob is adjusted to the maximum, there is no bottom noise, no white noise, the sound quality is pure without any impurities.

2>.Wide working voltage range, DC9-14V, current above 3A can work normally

3>.With output protection function, load short circuit, power amplifier board automatic protection, to prevent chip burnout

4>.Using the original TDK power inductor as the output, regardless of high-pitched, mid-range, bass performance is very good. The sound of any band with any detail of frequency response 20-20KHZ can be fully demonstrated

5>.Powerful, large dynamic range, small to squeak, big to cannon sound, can be very good performance, very small distortion! 8 ohm load is 2*10W, 4 ohm load is 1*20W

6>.Compared to the analog power amplifier, almost no heat, high efficiency, in the case of small size, can output more power

7>.With headphone playback function, making audio equipment connection easier

8>.The product uses our company high-speed placement machine patch, reflow soldering, wave soldering, product consistency, performance is very stable

9>.Support MP3, WAV format file playback; support USB, SD card online play.

10>.Support reverse power supply protection
