◆  Production Description

AP series amplifier utilises metal sealed pipe of Motorola. It is kind of professional amplifier with high power, multi-function, high quality, beautiful tone and good stability for indoor or outdoor performance. In order to achieve public praise, AP series amplifier has been improved many times for appearance design, interior construction, circuit design and tone expression. Now it is with outstanding tone analysis and expression performancce， and could be a leading product in the industry. It is also capable of comparing with famous brand overseas. The stability of the whole machine is also implemented with repeatedly broken tests.The completed function for application shows the humanize design of AP series amplifier.

◆ Function Feature:

AP series utilises H-grade line array arrangement with big-poor filter capacitor to ensure strong output of dynamic electric current. In the machine, there is high/low pass filter with independent A/B channel, which ensures it can meet requirements from different field.

For AP series, there is 80% parts assembled by automatic SID technic, so it can completely ensure products are standard.From parts to the whole machine, it is produced in scientific assembly line, it reduces the probability of mistake of workers, and makes better ensurance for the unity of products quality.

AP series is a special design for project. For each model of machine, it is with advanced technology for durability and stability, and is also made good selection from transformer, poor capacity, put capacity, and  transistor, etc. It makes sure for perfect output with low distortion, even when the driver loaded impedance is low, so keeps balance for the tone and speaker system. Therefore, PA series is really suitable for large and complicated speaker project.

◆ Circuit Protection :

●  The circuit protection for AP series is not only focus on protecting the surface of the speaker, but more importantly is to make it more suitable for bad working environment and make it work more comfortably.

●  AP series utilises more perfect themo-control protected circuit , so to solve the problem of damage for heavy heat. When the temperature reachs 85℃ in the machine, the power will be cut off the speaker. When the temperature draws back to 80℃, the speaker will automaticly recover to work normally.

●  The circuit breaker function of AP series, makes sure that the speaker will be safe and works well enven when the operator does some mistakes or something unexpected happens.(it needs to restart when circuit breaking)

●  AP series have special protect for over current, over voltage, over loading, and restrict range automaticly. The soft switch asures to protect the speaker work normally in any cases.

◆ Material of Amplifier

AP2550 utilises 8 pairs of metal sealed pipes of Motorola + 8 pairs of plastic sealed pipes of Toshiba, and new style aluminum alloy panels + U shape machine for heat dispersion.
