Thank you for purchasing Audiopole PA 4-250. This amplifier has 4 independents channels of 250 W each
which can drive loads of 4 Ohms, 70 V and 100 V for Public Address applications.
Unlike most 100 V amplifiers, PA 4-250 does not use output transformers, which allows to power the speakers
with a high quality signal. In addition, Class-H technology brings a gain weight and space while offering high-
yield performances. One of the main applications of the PA 4-250 is the amplification of independent zones
using low impedance outputs for near field and 100 V line for long distance speakers. The device concentrates
all the settings on the rear panel and control leds on the front panel; it allows full monitoring of the amplifier
status.
