General Description:

The Electro-Voice® PA2250T is from the PA series of
professional commercial audio amplifiers. The direct path
airflow design reduces the heat buildup significantly and
allows more amplifier channels and output power in slim
two rack space chassis. The audio performance of the
PA2250T is superior and fulfills the requirements in many
demanding long term applications from sound
reinforcement, paging or life safety installations.

High performance torroidal power and output transformers
combine clean saturation free audio performance with cool
running operation. The PA2250T 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 PA2250T provides excellent
headroom for a wide dynamic range on music signals. The
onboard dynamic limiter ensures that the output clipping of
the PA2250T will not generate excessive distortion. The
amplifier channels can be bridged for more power flexibility.
Marked level controls on the rear panel provide hidden
reliable level adjustments for each channel. Front panel
LEDs indicate signal present, 0 dB, and limit. Phoenix type
connectors for inputs and outputs provide an easy rack wiring.
