General Description:
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 P A4150 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.
