e 2-Band Equalizer (Bass, Treble)
Level adjustments for the low frequency (Bass) and high frequency (Treble) ranges.
r Mic Type Switch (Mic. type 1/2)
Selects the simulated mic type used in the SRT function. Each press of the switch (Blend
knob) toggles between Mic. type 1: Condenser and Mic. type 2: Ribbon.
t
Blend Control
Controls the mix level of signals received from the pickup and the simulated mic. Rotate fully
to the left for 100% pickup signal and fully to the right for 100% simulated mic signal.
y
AFR (Auto Feedback Reduction) Switch
If you experience problem feedback while performing, follow the AFR setting
instructions below to effectively control the feedback.
1. When feedback occurs, press the AFR switch (Bass control knob) after all sound other than
the feedback has been muted.
2. The system automatically detects the frequency causing the feedback and applies a –12dB
notch filter.
* The system may not be able to detect the problem frequency if two or more sounds
are present at the same time.
3. Pressing this switch when the AFR system is active (
w LED is lit green) switches the AFR
function OFF. Alternatively, switch off the power (unplug cable from output jack) to cancel all
notch filters.
u
Sound Hole Cover (included)
Inserting the sound hole cover into the sound hole effectively reduces feedback.
