The direct path airflow design reduces the heat buildup significantly and allows for more amplifier channels and output power in slim two rack space chassis. The audio performance of the PA2450L is superior and fulfills the requirements in many demanding long term applications from sound reinforcement, paging or life safety installations. The PA2450L features many of the same comprehensive protection circuits typical in EV amplifiers. Rated Load for Bridged Operation is 8 Ohms. 4 Ohm Load is Not Recommended.
