Description
PA series powered amplifer utilises metal sealed transistors of Motorola. It is a kind of professional amplifer with high power, multi-function, high quality, beautiful tone and good stability for indoor or outdoor performance. In order to achieve public praise, PA series amplifer 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 equipment is also implemented with repeatedly broken test. The completed function for application shows the humanized design of PA series powered amplifer.
Function Feature
PA series utilises H-grade line array arrangement with big-poor flter capacitor to ensure strong output of dynamic electric current. In the equipment, there is high/low pass flter with independent A/B channel, which ensures it can meet requirements from different felds.
For PA series, there are 80% parts assembled by automatic SID technic, so it can completely ensure products are standard. From parts to the whole equipment, it is produced in scientifc assembly line, it reduces the probability of mistake from workers, and makes better ensurance for the unity of products quality.
PA series is a special design for project. For each model of equipment, it is with advanced technology for durability and stability, and is also made good selection from transformer, poor capacity, input 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 PA 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.
PA series utilises more perfect themo-control protecting circuit, so to solve the problem of damage from heavy heat. When the temperature reaches 85°C in the machine, the power will be cut off from the speaker. When the temperature draws back to 80°C, the speaker will automaticly recover to work normally.
The circuit breaker function of PA series, makes sure that the speaker will be safe and work well even when the operator does some mistakes or something unexpected happens. (it needs to restart when circuit breaking)
PA series have special protect from over current, over voltage, over loading, and restrict range automaticly. The soft switch assures the speaker works normally in any cases.
