FLP-PA-4500D
4-Channel Class-D Power Amplifier
Redesign and upgraded, the new PA4500-D comes in 1.5U instead of the previous 1U for better ventilation and stability.
The PA4500-D comes with a power saving mode, capable of saving power up to 85% thanks to its APFC (Active Power
Factor Correction) prove to be a highly reliable and adaptive power amplifier.
Designed with the environment in mind, the PA4500 generates much lower heat (less than 55ºC even in extreme
condition). The output power for this amplifier ranges from 120W to 500W. Its sleek design enables it to be used as both a
tabletop or as a rack-mount unit in a 1.5U height rack.
