The NOTCH FILTER is effectively off in the full counter-clockwise position. VOLUME CONTROL The Volume control goes from very quiet to very loud. BASS, & TREBLE CONTROLS These are boost/cut shelving tone controls. The center detent yields a flat response. MIDDLE & BRILLIANCE CONTROL These are resonant style boost/cut filters. When boosted, the BRILLIANCE control can add presence to your sound or brighten up dead strings. When cut, the MIDDLE control "scoops" out harsh midrange frequencies. PHASE SWITCH The PHASE switch compensates for acoustic phase differences that often occur between instrument and speaker. It can be used as a tone filter at low volume levels or a feedback filter at high levels. The PHASE switch can correct any electrical phase difference between the PREFIX PRO system and an outboard instrument microphone. Flip the PHASE switch several times and use your ear to find the optimum setting. The best position for the PHASE switch may change, depending on the sound system and/or venue acoustics. 4 A COUSTIC G UITAR S YSTEM SUGGESTED EQ SETTINGS These settings are meant to be used as a starting point for building your sound.
