Gain Low Mid High Brilliance ip Anti Feedback Phase Loudbox Pro TM Off Phase Use the phase switch in conjunction with the Anti-Feedback filter to eliminate acoustic feedback. Gain Low Mid High Brilliance Anti Feedback Phase oudbox Pro TM Off 5 About Acoustic Feedback Feedback usually occurs in the lowest octave of your instrument, generally with two notes about a half step apart. Like blowing air across a bottle, the lower type of feedback (cavity resonance) starts when the sound pressure coming out of the speakers excites the resonant air chamber inside your instrument. We have found that it is effective to tune out an instrument's cavity resonance feedback with the Anti-Feedback (notch filter) in the Loudbox. For acoustic guitar this occurs at G# on the low E-string, or at about 100Hz. Turn the Anti-Feedback knob to about 11 o'clock to dial out this resonance. Note that the circuit can be effectively defeated by moving the dial to the OFF (7 o'clock ) position. The higher range of feedback (top resonance) usually starts about a half or whole step above cavity resonance of the instrument. Top resonance feedback happens when the sound pressure coming off the speakers excites the resonant frequency of the soundboard of your instrument. For acoustic guitar this occurs at A and above on the low E-string. Push the Phase switch in and out until you find the position that subdues top resonance feedback. Front Panel - Channel 2 (microphone or instrument channel) Channel 2 XLR Phantom Power Gain Low XLR Input Plug in any balanced dynamic or condenser microphone here. You may also connect an outboard preamp with balanced XLR out to this input. This control affects how well the instrument blends in or stands out in the mix. At loud volumes a midrange cut will achieve a more natural sound. With the dial set at 12 o'clock, the control is effectively out of the circuit. Clip Gain Low Mid High Brilliance Anti Feedback Off High Shelving treble, ±12dB @ 10kHz. Boost highs to add "air" to the sound of the instrument. With the knob set at 12 o'clock, the control is effectively out of the circuit. Clip Gain Low Mid High Brilliance Anti Feedback Off Brilliance A resonant-style tone circuit, ±12dB @ 10kHz. Add presence and "zing" to high frequencies. With the knob set at 12 o'clock, the control is effectively out of the circuit. Clip Gain Low Mid High Brilliance Anti Feedback Off Anti-Feedback A fixed-level, variable-frequency notch filter -14dB @ 20 - 400Hz. If you encounter low-frequency feedback, sweep this control to isolate and eliminate it. Many guitars will benefit with the Anti-Feedback knob set at about 11 o'clock. The Anti Feedback filter is off at the 7 o'clock position.
