Hartke AC150 Acoustic Ribbon Amplifier

Designed in a precision tuned Kickbackâ„¢ enclosure, with four custom-voiced 5-inch full ranged drivers arranged in stereo, and a 2-inch by 4-inch ribbon tweeter, the AC150 naturally recreates the sound of the acoustic instrument without adding any unwanted coloration or distortion. Channel 1 has active and piezo instrument inputs, with bass and treble controls, while channel two has XLR microphone and RCA line inputs. There is a 5-band graphic EQ and a built-in 100 preset 24-bit stereo digital effects processor, which can be routed to either channel.

The AC150 features a 150 watt tri-amped design, with 50 watts powering the left and right full range speakers and 50 watts powering the high frequency ribbon tweeter. To reduce feedback, there is a phase switch on channel 1 as well as a variable notch filter with depth control. On the rear panel of the amplifier there is an effects loop with stereo return, and stereo XLR direct outputs.

Simply put the Hartke Acoustic Ribbon amplifiers sound like your instrument, only louder.
