EV PA2250T
DUAL 250 W/CH POWER AMPLIFIER
EV 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.
EV 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.
