PFA6K4 800W 4 Channel Digital Professional Audio Power Amplifier PFC Class D DSP Amplifier Sound Equipment/amplifiers/speaker

1.◆◆Application scope:

On site sound reinforcement and fixed installation (such as theater, stadium, multi-function hall, large venues, outdoor mobile performances, etc.)

2.◆◆Product features

Advanced Class D output circuit.

Advanced switching mode power supply.

Heat dissipation of temperature controlled continuous variable speed fan.

Comprehensive protection circuit (thermal protection, clipping limiter, short circuit protection, etc.)

Lightweight and compact.

3.◆◆Low calorific value:

Low calorific value means that there is no need for a large heat sink, and the equipment runs quieter and has a longer life.

4. ◆◆Thin and lightweight:

Due to high efficiency and low heat dissipation requirements, the digital power amplifier can be designed to be very compact and suitable for scenes with limited space.
