    Hartke AC75


    Hartke has taken its experience in building great sounding bass amplifiers and brought it to the field of acoustic guitar amplification with the introduction of the Hartke Acoustic Ribbon Series. Perfect to go from the coffee house to the night club, the AC75 is a two channel 75 watt acoustic guitar combo.Designed in a precision tuned Kickback™ enclosure, with two custom-voiced 5-inch full range drivers which naturally recreate the sound of the acoustic instrument without adding any unwanted coloration or distortion, and a 2-inch by 4-inch ribbon tweeter which adds clarity and overtones to the high end. 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 digital effects processor, which can be routed to either channel.The AC75 features a 75 watt bi-amped design, with 50 watts powering the full range speakers and 25 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, and XLR direct outputs.Simply put the Hartke Acoustic Ribbon amplifiers sound like your instrument, only louder.
