PA 4500 L

4 x 500 W (70/100V) amplifier.

4x500W (70/100V) amplifier

PA 4500 L is a 4-channel, class-D installation amplifier with 500W per output. It is suitable for both 70/100V line installations (selectable through dip-switches). Each channel has its own volume control and LED indicators (signal, clip and protection). 

PA 4500 L amplifier has several protections such as short circuit, thermal, ultrasonic and RF. The input and output connections are made through Euroblocks, and it is 1HU for 19'' standard racks.
