• EQ Faders: Adjust the level of each of the 9 frequency bands. Move a fader up to boost the frequency, or down to cut it. The range can be set to +/- 6 dB or +/- 12 dB using the GAMMA interruptor.
• Control de NIVELL: Adjusts the overall output level of the equalizer.
• INPUT/OUTPUT Meter: A 6-digit LED meter displays the input or output signal level, selectable via the I/O METER botó.
• FBQ Mode Button: Activates the Feedback Detection System. When active, the LEDs on the EQ faders will illuminate brightly at frequencies where feedback is occurring, allowing for quick identification and reduction.
• LOW CUT Button: Engages the low-cut filter, which attenuates frequencies below 75 Hz to remove unwanted low-end noise.
• EQ ON/OFF Button: Bypasses the equalizer section. When off, the signal passes through the unit without EQ processing.
• Botó d'encendre: Encén o apaga la unitat.

4.2. Using the FBQ Feedback Detection System

To utilize the FBQ system, press the FBQ MODE button. During operation, if feedback occurs, the LED corresponding to the problematic frequency band will light up. Gently lower the fader for that specific frequency band until the feedback is eliminated. This system also functions as a visual audio analyzer, showing which frequencies are most prominent in your signal.
