Description

Technical Field

[0001] This utility model relates to the field of power amplifier technology, specifically to an adjustable power amplifier. Background Technology

[0002] Power amplifiers, as common electronic devices, are widely used in communications, audio, broadcasting, and other fields. Existing power amplifiers typically have power regulation functions, allowing adjustment of output power via control panel or external signals; this technology is relatively mature. However, existing technologies still have significant shortcomings in the installation and mounting methods of power amplifiers.

[0003] Currently, power amplifiers are mostly installed in cabinets using bolt fixing, which has the following problems:

[0004] 1. Cumbersome installation: Bolt fixing requires multiple tightening operations with the help of tools, which is time-consuming and labor-intensive, especially in the narrow space of the cabinet.

[0005] 2. Difficult to maintain: When the power amplifier needs to be maintained or replaced, the bolts must be removed one by one, which is not only inefficient, but may also cause damage to the equipment or cabinet due to improper operation.

[0006] Therefore, we propose an adjustable power amplifier. Utility Model Content
