3.1 Connexió de dispositius d'àudio

The EQ5 supports both Stereo RCA and 3.5mm AUX inputs and outputs. These inputs and outputs are in parallel, meaning they will work simultaneously. To avoid audio mixing issues, please do not connect RCA and 3.5mm AUX inputs at the same time.

1. Connexió d'entrada: Connect your audio source (e.g., CD/DVD player, TV, tablet, phone, laptop) to the EQ5's 'IN' ports using either RCA cables or a 3.5mm AUX cable.
2. Connexió de sortida: Connect the EQ5's 'OUT' ports to your audio receiver (e.g., amplifier, active speakers, headphone amplifier) using either RCA cables or a 3.5mm AUX cable.

3.2 Connexió d'alimentació

The EQ5 requires a DC 5V power supply (minimum 500mA) via its USB Type-C port for the EQ preamplification function to operate. A USB Type-C cable is included in the package.

• Connect the provided USB Type-C cable to the '5V IN' port on the rear of the EQ5.
• Connect the other end of the USB cable to a dedicated DC 5V power adapter (not included).
• Important: Do not use the USB port of computers or share the power supply with your audio source, as this can cause common ground noise.

3.3 Attaching Rubber Feet

Attach the four included rubber feet to the bottom of the EQ5 unit to prevent slipping and protect surfaces.

• Press the 'Power button' on the front panel to turn the unit on or off. The 'Power indicator' light will illuminate when the unit is on.

4.2 Adjusting Equalization

The EQ5 features five independent adjustment knobs for different frequency bands:

• 100Hz: Controls the lowest bass frequencies.
• 400Hz: Adjusts the mid-bass range.
• 800Hz: Manages the lower-midrange frequencies.
• 4 KHz: Controls the upper-midrange and lower treble.
• 10 KHz: Adjusts the highest treble frequencies.

Rotate each knob to increase or decrease the gain (±10dB) for its respective frequency band, tailoring the sound to your preference.

4.3 Using the Bypass Function

The EQ5 includes a bypass button to turn off EQ preamplification. When activated, the audio signal will pass directly from the input to the output without any processing from the equalizer. This allows you to conveniently compare the processed sound with the original audio.

• Press the 'Bypass button' on the front panel to toggle the EQ function on or off.
• In bypass mode, the EQ5 can function without a DC 5V power supply.

  • Check if the bypass function is engaged. If so, ensure your connected amplifier/speakers are powered on and volume is adjusted.
  • Confirm the audio source is playing and its volume is adequate.
• Distorted Sound or Noise:
  • Common Ground Noise: If you experience humming or buzzing, ensure the EQ5 is powered by a separate DC 5V power adapter and not from a computer's USB port or shared with the audio source.
  • Check cable quality and ensure they are not damaged.
  • Reduce the gain on the EQ bands if the sound is overdriven.
• EQ Adjustment Not Working:
  • Ensure the EQ5 is powered by a DC 5V adapter. The EQ preamplification function requires power.
  • Verify the bypass button is disengaged (EQ function is active).
• No Power in Bypass Mode:
  • This is normal. The EQ5 can pass audio in bypass mode without external power, but the EQ function itself will not be active.
