FISHMAN PREFIX™ PLUS
4
VOLUME CONTROL
Controls the overall gain of the PREFIX PLUS™. Goes from very quiet to very loud.
BASS CONTROL
This is a boost/cut shelving tone control. The center detent yields a flat response.
CONTOUR
This is a Wide-range semi-parametric filter. It is used to selectively shape the instru-
ment's tone.
The CONTOUR Level slider controls the amount of boost or cut applied to the selected
Contour FREQUENCY. The center detent yields a flat response.
The Contour FREQUENCY slider determines the frequency band that is boosted or cut
by the CONTOUR LEVEL control. The frequency is variable from 250 to 10 kHz.
TREBLE CONTROL
This is a boost/cut shelving tone control. The center detent yields a flat response.
BRILLIANCE CONTROL
This is a resonant style boost/cut filter. When boosted, the BRILLIANCE control can add
presence to your sound or brighten up dead strings.
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™ 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.
