Company Advantages
1. The design of Gisen sound power amplifier involves many considerations. They may include stress points, support points, yield points, wear resistance capacity, toughness, and friction force.
2. The testing data of the product is accurate and relible.
3. The implementation of the complete quality management system greatly guarantee that the product is manufactured according to the international quality standards.
4. With proper thread count, the product has a soft touch. Especially after washing a few times, it will be felt softer.
5. With this product, the sleep will not be interrupted again which includes sweating and would interfere with the natural sleep cycles.

FP series amplifiers are with switch power supply. Its compact and precise structure makes it high-performance. Each channel has independent adjustable peak output voltage, which enables the amplifier to drive speakers with different power easily. Intelligent protecting circuit provides advanced technology to protect the internal circuits and connected loads, so that the amplifiers and speakers can still be operated in extreme conditions. Applied to situations like Performance, Night Club, etc.
