Company Advantages
1. Gisen multi channel stereo amplifier is of various modern and stylish designs. Attention has been paid to the circuit layout for safe operation
2. Guangzhou Gisen Audio Equipment Factory has a large-scale standardized best audio amplifier production base covering an area of thousands of square meters. It delivers different ranges of voice volume without sacrificing audio quality
3. The product has a strong energy storage system. Its deep cycle battery stores a huge amount of solar source for overnight or blackout operation. It can support multiple devices via the interface
4. The product has the advantage of strong electromagnetic compatibility. Having passed discharge tests and surge tests, it produces no intolerable electromagnetic interference to the environment. No matter there is a short circuit or long-time full-load working, it can quickly stop working for security

GISEN MD series amplifiers are powered by toroidal transformer, along with its hi-fi driven circuit, makes the low frequency powerful and mid & high frequency clear. The electronic volume control can affectively preventing interference like the traditional potentiometer. Applied to KTV, stadium, performance, meeting, entertaining clubs, etc.
