Radial Engineering AC-Driver - Compact Acoustic Preamp

The AC-Driver™ is a compact yet powerful preamp for acoustic instruments on stage. EQ and volume adjustments provide you with complete control over your tone, in a rugged steel chassis with heavy duty components that will withstand the harshest touring environments. A variable low cut filter removes excessive low frequencies, along with a notch filter and a 180° polarity reverse switch to help eliminate feedback. The notch filter features a three position switch that allows you to select between a normal or deep notch, or remove it from the signal path altogether. A balanced XLR output feeds the PA system or a powered speaker, while a ¼” output can be used to simultaneously connect to an amplifier. The AC-Driver also features an always-on ¼” tuner output and a dedicated Mute footswitch, allowing for silent tuning on stage.

The AC-Driver allows you to obtain great sounding results in a short amount of time, with powerful easy-to-use controls that allow you to set your levels and reduce on-stage feedback. An adjustable low cut filter removes excessive low frequencies, while a 180° phase switch helps correct feedback build-up from hot spots on stage. A variable notch filter targets and removes specific problem frequencies, and a mute footswitch provides a way to silently tune on stage or change instruments without any popping or noise in the PA.
