Product Description

■ Class-D (Transformer Amplifier) - K Series

● This is a new route of using the latest work "Class-D" borne power amplifier.

● Both retained the sound characteristics of class H lines, and application of the working principle of class D digital power amplifier, increases the working efficiency of the machine from the original H class to raise about 60% to 85%.

● Due to the fundamental change from the circuit design, make the machine has the full power, to achieve the real "small volume, sufficient power".

● At the same time, set up a variety of protection circuit. Include: short circuit, compression, pressure limit, over current, over voltage, over temperature, dc, distortion and frequency, and there is the function of the volume too large, makes the machine is easy to use no matter how bad environment in response.

● This is a highly optimized circuit design of the machine, to the machine with high cost performance.

● Served with a switching power supply or transformer two forms of power supply.

The quality of Gisen power amplifier can be guaranteed by its hygienic license issued by the Health Supervision Department. Both its physical and chemical filtration systems are in line with the standards required in the pure drinking water. The product is equipped with a GPRS remote management monitoring system
Gisen home amplifier is often of customized design which links into the product’s or brand’s characteristics and will subsequently emphasize or even strengthen the ‘feeling’ of these features. It is widely used in campus, subway, airport, shopping malls, hospitals, hotels, etc
Gisen 1u 4 channel amplifier will go through a series of quality control process, including the raw materials ingredients, the quality of dyeing agents, as well as the strength of the final product. The glass of the display window is mist resistant, allowing the merchandise to be clearly displayed at all times
The quality of Gisen home amplifier is assessed with a series of physical and mechanical tests. These tests include abrasion or piling performance, dimensional stability, weather testing, thermal and water vapor resistance, etc. With a micro-computer control system, it is able to check the sales data
The quality of Gisen power amplifier is ensured. It has passed laboratory tests for air, water, and structural resistance, heat transmission, condensation resistance, sound transmission, and operability. The ads can be printed on its shell, which brings double profit to the investor
The product is not prone to oxidization. Through an electrical process to form a certain layer of an anodic layer on its surface, it is not affected by the air or moisture. With a micro-computer control system, it is able to check the sales data
