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.
