The 1/4″ input accepts all types of passive or active acoustic pickups. Plug a balanced mic into the XLR input for vocal or instrument use.
Gain
Use the Gain knob to set the level of the signal.
Bass
Boost here to add weight to the sound. In general, boost bass at low volumes and flatten it out(or cut) at higher levels.With the dial set at 12 o’clock,the control is effectively out of the circuit.
Mid
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.
Treble
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.
Phase
Use the Phase switch in conjunction with the Anti-Feedback filter to eliminate acoustic feedback.
Resonance
If you encounter low-frequency feedback, sweep this control to isolate and eliminate it.
Reverb
Determines the length of time for the delay or reverb effects.
Effect
