u******c

In the researching and developing stage of Gisen class d mono amplifier, the R&D has integrated different water purification techniques which meet the domestic pure water standard. Its solid conductors help eliminate strand-interaction distortion and reduce jitter

i******r

There are several major production processes included in Gisen class d amplifier manufacture, namely, materials opening and cleaning, loosening the fibers, lapping, dyeing, and printing. This product is easy to plug and play

f******u

The electrode materials of Gisen class d mono amplifier are carefully delivered to the factory in the form of black powder that is almost indistinguishable. Using foamed PE as the insulation, this product features a quality signal

b******e

The design of Gisen class d mono amplifier is developed using a 3D CAD program. CAD models are created for the individual parts and the subassembly showing how the parts are connected together. Its length can be customized according to needs

g******h

The quality control of Gisen class d amplifier begins with the selection of its components or parts. All of the components must go through chemical spraying soak tests, including, salt spray, acid and alkali pickling, and corrosive liquid dipping test. This product features high-speed endurance and compatibility

u******j

A quality assurance system has been established and improved to place the product's performance indicators at the forefront of the industry. It has been accepted by the consumer/ institutional electronics industry
