Size ： 64MM × 45MM × 17MM (L W H)
12V DC power supply, current 3A above.
Feature：
Proprietary digital processing technology
Integration of sonic boom noise generated when the switch circuit can be eliminated.
Intelligent short circuit protection.
Intelligent overheating protection
It can be connected to any passive 4 / 8Ω speakers.
Compatible with any sound systems standard audio cable.
It requires only a single power supply 12V, easy to use
Output Power (per channel @ VS = 12V):
15W per channel (4Ω, 10% THD + Noise)
10W per channel (4Ω, 0.10% THD + Noise)
Hi-fi performance "generally refers to:
0.04% total harmonic distortion plus noise (9Wrms, 4Ω)
0.18% intermodulation distortion (1Wrms, 4Ω)
Efficiency -> 88% @ full power (RL = 8Ω)
Amplifier Precautions
1. The power 12V ,current 3A above.
2. Use the best speaker impedance of 4 ohms, sensitivity a little high.
3. The signal level relatively low audio, you need to add pre-amplifier, the effect is even better.
4. Note the positive and negative can not be reversed, it is best to use regulated power supply.
