4. Power On: Press the POWER button on the front panel to turn on the equalizer. The power indicator light will illuminate.

6. Operating Instructions

Once the equalizer is set up and powered on, you can begin adjusting your audio:

6.1. Equalization Control

The EQ-7 features seven rotary knobs, each corresponding to a specific frequency band:

• 60Hz: Controls the deepest bass frequencies.
• 150Hz: Adjusts mid-bass frequencies.
• 400Hz: Affects lower midrange frequencies.
• 1KHz: Controls central midrange frequencies.
• 3KHz: Adjusts upper midrange frequencies.
• 6.5KHz: Affects lower treble frequencies.
• 15KHz: Controls the highest treble frequencies.

Rotate each knob clockwise to boost (increase) the corresponding frequency band by up to +12dB, or counter-clockwise to cut (decrease) it by up to -12dB. The center position represents a flat (0dB) response for that band.

6.2. Volume Control

The VOLUME knob controls the overall output level of the equalizer. Rotate it clockwise to increase the volume and counter-clockwise to decrease it. Adjust this to your desired listening level.

6.3. 3.5mm Headset Functionality

When using the 3.5mm input with a 4-pole headset (headphones with an integrated microphone), the equalizer supports normal mobile phone voice calls. The output from the 3.5mm jack can be connected to headphones with a microphone for this purpose.

7. Maintenance

To ensure the longevity and optimal performance of your Gugxiom EQ-7, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Avoid using harsh chemicals, solvents, or abrasive cleaners.
