[. . . ] To conserve the battery, remove the instrument cable from the endpin jack when the unit is not being used. NOTE: Plug an instrument cable into the endpin jack before you plug into the sound equipment. Doing so will prevent loudspeaker damage. BATTERY LOW LED When plugging into the endpin jack, the LOW BATTERY light will flash momentarily, indicating that the power is on. When the LOW BATTERY light stays on, it is time to change the battery. 3 F ISHMAN P REFIX TMP RO CONTROLS NOTCH FILTER This is a fixed level, variable-frequency filter for eliminating feedback or unwanted resonance. The affected frequency is variable from 40 to 500 Hz. 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. MID CUT This is a good all-around setting. You can also cut midrange by boosting the BASS and TREBLE sliders to realize an implied mid-cut at 800 Hz. BRILLIANCE If you are playing through a guitar amplifier or have dead strings on the instrument, you can brighten up your sound with this setting. 5 F ISHMAN P REFIX TMP RO SUGGESTED EQ SETTINGS, CONTINUED CUT THROUGH THE MIX For cutting through a live band mix at high volumes.
