Power Amplifier
Products
In China, AISP is the leading power amplifier manufacturer and supplier. We specializes in manufacturing and supplying top-quality Wholesale Power Amplifier products designed for a wide range of professional audio applications. Our power amplifiers deliver reliable, high-fidelity sound amplification suitable for venues such as conference halls, auditoriums, entertainment centers, and large public spaces. We support B2B clients worldwide with competitive pricing, OEM customization, and dedicated technical support.
Our power amplifiers support 70V and 100V constant-voltage speaker systems as well as 4–16Ω low-impedance output. This makes them suitable for both distributed PA systems with multiple speakers and professional audio installations requiring low-impedance speaker connections.
AISP power amplifiers can be integrated with audio mixers, microphones, paging controllers, audio processors and different types of PA speakers.
AISP currently offers two main power ranges for different project sizes.
| Product Series | Rated Power | Recommended Project Type |
|---|---|---|
| PA-360 / PA-460 / PA-660 | 360W / 460W / 660W | Small and medium-sized commercial PA systems |
| PA-1000 / PA-1500 / PA-2000 | 1000W / 1500W / 2000W | Large speaker networks and high-power PA projects |
The 360W, 460W and 660W models are suitable for projects such as schools, shops, conference facilities, houses of worship and medium-sized public areas.
For larger systems with more speakers or higher total speaker loads, the 1000W, 1500W and 2000W models provide additional output capacity. They can be considered for transportation facilities, industrial sites, large commercial buildings, outdoor areas and centralized public address systems.
·High Power Output and Stability: Our power amplifiers provide stable and efficient power output ranging from 100W to 2000W. Utilizing advanced Class-D and Class-AB amplifier technologies, AISP ensures clear sound quality, low distortion, and excellent thermal management for continuous operation.
·Wide Compatibility and Connectivity: The amplifiers are equipped with versatile input and output options, including balanced XLR, RCA, and Speakon connectors, allowing seamless integration with mixers, audio processors, and speaker systems in various commercial setups.
·Robust Protection and Durability: Built with multiple protection circuits against overcurrent, short circuit, overheating, and DC offset, AISP power amplifiers guarantee safe and durable operation even in demanding environments.
Selecting a public address power amplifier requires more than choosing the model with the highest wattage. Buyers should first identify the speaker system type and calculate the total connected load.
Choose a 70V or 100V power amplifier when the project uses multiple transformer-equipped PA speakers connected through a distributed speaker line.
Choose the 4–16Ω output only when the connected speakers and system wiring are designed for low-impedance operation.
Do not connect low-impedance speakers directly to a 70V or 100V output unless the speaker includes a compatible transformer and input tap.
For a 70V or 100V system, add together the selected power tap of every connected speaker.
For example, when twenty speakers are each set to 10W, the connected speaker load is 200W. The selected amplifier should have a rated output above the total connected load so that the system is not continuously operated at its maximum capacity.
Additional capacity should also be considered when the customer plans to add more speakers later.
A standard power amplifier normally amplifies the incoming audio signal but does not independently control multiple speaker zones.
Projects requiring separate volume adjustment, source selection or paging in different areas may also require an audio matrix, zone selector, multi-zone amplifier or PA system controller.
Confirm how the amplifier will receive audio. Possible sources include:
Audio mixer
Paging microphone
Digital audio processor
Network PA terminal
Background music player
Emergency announcement controller
Conference audio system
The input level and connector type should match the upstream equipment.
Buyers should verify the required AC input voltage according to the destination country. Projects requiring emergency or backup operation should also confirm whether a compatible 24V DC power input is available.
These amplifier types serve different purchasing requirements.
| Amplifier Type | Main Function | Suitable Applications |
| Power amplifier | Amplifies an external line-level audio signal | Systems already equipped with a mixer, controller or audio processor |
| Mixer amplifier | Combines microphone, AUX and media inputs with amplification | Small and medium-sized standalone PA systems |
| Multi-zone amplifier | Provides amplification and zone management | Buildings requiring separate broadcasting areas |
| Class-D amplifier | Uses a high-efficiency amplifier topology | Projects prioritizing lower power consumption, reduced heat and compact size |
A dedicated power amplifier is generally selected when the project already has a mixer, preamplifier, audio matrix or central PA controller.
For a smaller installation that requires microphone inputs, music playback and speaker output in one device, a mixer amplifier may provide a simpler configuration.

A power amplifier primarily increases a line-level audio signal so that it can drive speakers. A mixer amplifier also includes microphone, AUX or media inputs, allowing it to mix audio sources and power speakers in one unit.
Yes. A 70V or 100V power amplifier can connect to multiple compatible PA speakers. The total selected speaker wattage must remain below the rated output capacity of the amplifier.
Calculate the total wattage of all connected speakers and consider the required operating margin and future expansion. Smaller systems may use a 360W, 460W or 660W amplifier, while larger speaker networks may require a 1000W, 1500W or 2000W model.
A dedicated power amplifier normally receives a line-level signal from a mixer, preamplifier or PA controller. Projects requiring direct microphone inputs should consider a mixer amplifier or add an external audio mixer.
Yes. OEM options may include logo branding, front panel design, packaging and selected technical specifications, subject to order quantity and project requirements.
