6. Instruccions de funcionament

The Douk Audio T7 allows for precise control over your audio's frequency response.

1. Power On and Input Selection: Rotate the leftmost knob to select your audio input (RCA or BAL). This action also powers on the unit.
2. Adjusting Equalization: Use the seven individual frequency adjustment knobs (64Hz, 125Hz, 250Hz, 500Hz, 2KHz, 4KHz, 8KHz) to boost or cut the gain for each specific frequency band. Each knob offers a range of -6dB to +6dB. Adjust these to tailor the sound to your preference, compensate for room acoustics, or correct speaker deficiencies.
3. Mode bypass: To listen to the original, unprocessed sound, turn the Input Selector / Power knob to the 'OFF' position. This activates the bypass mode, allowing the audio signal to pass through without equalization.
4. Sortida: Both XLR and RCA outputs function simultaneously, allowing you to connect to multiple devices if needed.
