Features
- Housed in a rugged,all-steel 2U chassis
- Unique radiator sctructure for efficient cooling.
- Designed for efficient with circuit protection to avoid the demage caused by the mistake operation.
- Power input overvoltage, undervoltage, anti-surge protection and switching impact protection.
- To avoid abnormal and failure of the PA system to cause damage to the speaker by DC output protection and high-frequency sustained energy limit
- Over temperature protection automatically
