Each of the two channels features:

• 31 Frequency Sliders: Control individual frequency bands from 20 Hz to 20 kHz.
• Input/Output Level Meters: LED indicators for monitoring signal levels.
• Gain Control: Adjusts the overall output level of the channel.
• FBQ Switch: Activates the Feedback Detection System.
• Low Cut Filter: Sweeps from 25 Hz to 250 Hz to remove unwanted low-frequency rumble.
• High Cut Filter: Sweeps from 2.5 kHz to 25 kHz to remove unwanted high-frequency hiss.
• Områdekontakt: Selects the boost/cut range for the sliders (±6 dB or ±12 dB).
• Bypass switch: Bypasses the equalizer section, allowing the signal to pass through unprocessed.

5.2 Basic Equalization

To adjust the frequency response of your audio:

1. Ensure all connections are secure and power is on.
2. Indstil Rækkevidde switch to ±12 dB for broader adjustments or ±6 dB for finer control.
3. Juster Gevinst control to achieve an optimal signal level, indicated by the input/output meters. Avoid clipping (red LEDs).
4. Flyt 31 Frequency Sliders up or down to boost or cut specific frequencies. Listen carefully to the changes in the audio.
5. Brug Lavt snit og Højt snit filters to remove undesirable frequencies at the extreme ends of the spectrum.

5.3 FBQ Feedback Detection System

The FBQ system helps identify and eliminate feedback frequencies:

1. Tryk på FBQ switch to activate the feedback detection mode.
2. When feedback occurs, the LEDs above the corresponding frequency sliders will illuminate brightly.
3. Gently lower the slider for the illuminated frequency until the feedback is eliminated or significantly reduced.
4. Repeat this process for any other feedback frequencies that appear.

Note: While effective, the FBQ system may require the feedback to be audible before detection. Adjusting sliders proactively based on room acoustics can also help prevent feedback.
