പ്രവർത്തന നിർദ്ദേശങ്ങൾ

1. പവർ ഓൺ/ഓഫ്

The device supports power on/off functionality and power-off memory. To turn on, press and hold the 'SET' button for 3 seconds. To turn off, press and hold the 'SET' button again for 3 seconds.

2. Adjusting Input Level (GAIN)

ഉപയോഗിക്കുക നേട്ടം knob on the back of the unit to adjust the input audio level. This helps in achieving the best visual beating effects on the LED display, matching the intensity of your audio signal.

3. Changing Display Effects

The VU56C offers 5 distinct display effects. In normal operating mode (not setup mode), use the PREV ഒപ്പം അടുത്തത് buttons to cycle through the different display effects:

1. പ്രധാന ബീം
2. Main beam + peak point drop
3. Left and right channel beams mirroring-display
4. Left and right channel beams mirroring-display + peak point drop
5. Spring beam (Note: This effect does not support setting item adjustments.)

4. Setup Mode and Parameter Adjustments

To enter setup mode, press the സെറ്റ് button briefly. In setup mode, the 'Flash LED' indicates the current setting option value. Use the PREV ഒപ്പം അടുത്തത് buttons to change the value of the selected parameter. Press the സെറ്റ് button again to move to the next option or to exit setup mode.

The adjustable parameters (each with 16-level speed adjustments) include:

• The descent speed of the main beam
• The descent speed of the peak point
• The stay time of the peak point

All setup parameter changes will be displayed in real-time on the 'Preview bar'.

മെയിൻ്റനൻസ്

To ensure the longevity and optimal performance of your Douk Audio VU56C, follow these maintenance guidelines:

• Keep the device in a clean, dry environment, away from direct sunlight, high temperatures, and humidity.
• Avoid exposing the unit to water or other liquids.
• മൃദുവായതും ഉണങ്ങിയതുമായ തുണി ഉപയോഗിച്ച് പുറംഭാഗം വൃത്തിയാക്കുക. കഠിനമായ രാസവസ്തുക്കളോ ഉരച്ചിലുകളുള്ള ക്ലീനറുകളോ ഉപയോഗിക്കരുത്.
• അമിതമായി ചൂടാക്കുന്നത് തടയാൻ യൂണിറ്റിന് ചുറ്റും ശരിയായ വായുസഞ്ചാരം ഉറപ്പാക്കുക.
• ശാരീരിക കേടുപാടുകൾ തടയാൻ ഉപകരണം ശ്രദ്ധാപൂർവ്വം കൈകാര്യം ചെയ്യുക.

ട്രബിൾഷൂട്ടിംഗ്

If you encounter issues with your Douk Audio VU56C, please refer to the following common problems and solutions:

No Display or Weak Display

• പവർ പരിശോധിക്കുക: Ensure the Micro-USB cable is securely connected to a DC 5V/100mA power source and the unit is powered on.
• Check Audio Input: Verify that the audio source is playing and connected correctly to the IN RCA ports.
• ഗെയിൻ ക്രമീകരിക്കുക: Rotate the GAIN knob to increase the input level. If the input signal is too low, the display may not activate or appear weak.

Audible Noise in Audio System

Some users have reported audible noise (hum or clocking noise) when the unit is connected in pass-through mode or even when splitting the audio signal. This can be due to grounding issues or power supply interference.

• Ground Set Switch: Try adjusting the 'Ground set' switch on the back of the unit. Default is 'I'. If you experience back noise, switch to 'O'.
• വൈദ്യുതി വിതരണം ഒറ്റപ്പെടുത്തുക: Use a different USB power adapter or a high-quality, isolated power supply.
• Audio Isolation: Consider using an audio isolation transformer or a mixing board between your audio source and the VU56C to electrically isolate the signal path.

Display Inaccuracy Between Channels

Due to the high resolution and MCU signal processing, a slight error of 1-3 bits between left and right channels may occur even with identical input signals. This is considered normal operation for this device.
