PA-1800 Professional Multi Purpose Amplifier Artcoustic has designed and engineered the PA-1800
Professional Multi Purpose Amplifier. The PA-1800 performs smoothly and accurately even in the most demanding
conditions. The PA-1800 is matched to all the Artcoustic loudspeakers’ impedance and tonality, making a perfect match with amazing detail, control and dynamics.
The PA-1800 offers incredible 3 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 high-end home cinema systems. It features 3 individual mono blocks with a total of 1500 watt. This makes it a stunning partner for Artcoustic’s passive subwoofers or for the ultimate performance when using multiple amplifiers
to Bi-amp the larger models in the DF and Spitfire range.
Artcoustic PA-1800 3 channel amplifier features
· 2 rack units high. Very high output with minimal rack space required
· Individual input sensitivity for each of the 3 channels.
· Signal presence and protection indicator.
· Balanced inputs via XLR and Jack connectors. Unbalanced input via RCA connectors.
· Stable performance down to 2 ohms.
· Each channel may be fed with independent signals, used for addressing different zones or fed with the same mono or stereo signal.
· High current bi-polar technology.
· Precision subharmonic filters.
· Triple monoblock amplifier PCB design.
· Extended protection curcuit.
· High efficiency toriodal transformer.
· Dual fan speed, setting 0 residential = silent, setting 1 commercial = full fan speed
· Totally protected against overheating and shorting and includes DC prevention at the output stage.
