The Electro-Voice® PA2450L is from the PA series of
professional commercial audio amplifiers. 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. Complete
protection is provided for high temperature, audio limiters,
power up delay and peak current limiters. In addition to the
rated output power, the PA2450L provides excellent
headroom for a wide dynamic range on music signals. The
onboard dynamic limiter ensures that the output clipping of
the PA2450L will not will not generate excessive distortion.
The amplifier channels can be bridged for more power
flexibility.
