The Electro-Voice® PA4150 is from the PA series of professional commercial audio amplifiers. The direct path airflow design reduces the heat buildup significantly and allows for 4 full amplifier channels in a slim two rack space chassis. The audio performance of the PA4150 is superior and fulfills the requirements in many demanding long term applications from sound reinforcement, paging or life safety installations.
The PA4150 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 PA4150 provides excellent headroom for a wide dynamic range on music signals. A selectable 50Hz or 300Hz hi-Pass filter makes it easy to incorporate the unit into The onboard dynamic limiter ensures that the output clipping of the PA4150 will not 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.
