PA-250 & PA-750 Professional Single Channel Amplifier
Artcoustic has designed and engineered the PA-250 & PA-
750 Professional Single Channel Amplifier. The PA-260 & PA-
& PA-750 performs smoothly and accurately even in the
most demanding conditions. The PA-250 & PA-750 is matched
to all the Artcoustic subwoofer’s impedance and tonality,
making a perfect match with amazing detail, control and
dynamics.
The PA-250 & PA-750 offers incredible single channel
performance in a rack mountable chassis just 2U high. This
together with it’s high performance and silent running dual
fan speed cooling system means it is suitable for almost any
application, from recording studios to commercial bars &
restaurants, high quality hi-fi and home cinema systems. It
features one single mono block with a total of 250 watt
8ohm and 750 watt 8ohm.
