• Podcasting with multiple microphones
• Live sound mixing and routing
• Audio signal processing and experimentation
• Integration with Arduino-based audio projects

The Dariyan-X 8ch features a USB interface for communication and power, along with 8 input and 8 output audio channels. Below is the pin configuration for the audio I/O ports:

1. Powering the Device:
   Connect the Dariyan-X 8ch to a 5V DC power source using the USB cable provided. Alternatively, you can use an external 5V DC power supply.

2. Connecting Audio Inputs and Outputs:

   • Use standard 3.5mm or 6.35mm audio jacks (depending on your setup) to connect microphones, instruments, or other audio sources to the input channels (IN1 to IN8).
   • Connect speakers, headphones, or other audio output devices to the output channels (OUT1 to OUT8).

3. Interfacing with a Computer:

   • Plug the USB cable into your computer. The Dariyan-X 8ch will be recognized as an audio interface.
   • Install any necessary drivers or software provided by Arduino for optimal performance.

4. Using with Arduino UNO:
   The Dariyan-X 8ch can be integrated with an Arduino UNO for advanced audio processing. Below is an example code snippet for initializing communication with the device:

#include <Wire.h> // Include the Wire library for I2C communication

void setup() {
  Wire.begin(); // Initialize I2C communication
  Serial.begin(9600); // Start serial communication for debugging

  // Send initialization command to Dariyan-X 8ch
  Wire.beginTransmission(0x48); // Replace 0x48 with the I2C address of the device
  Wire.write(0x01); // Example command to initialize the device
  Wire.endTransmission();

  Serial.println("Dariyan-X 8ch initialized successfully.");
}

void loop() {
  // Example: Read audio data or control the device
  // Add your custom code here
}

• Ensure that the power supply voltage does not exceed 5V to avoid damaging the device.
• Use shielded audio cables to minimize noise and interference.
• When using the device with an Arduino, ensure proper grounding to prevent audio artifacts.
• For optimal performance, use high-quality audio sources and output devices.

1. Device Not Recognized by Computer:

   • Ensure the USB cable is securely connected.
   • Check if the necessary drivers are installed.
   • Try using a different USB port or cable.

2. Audio Distortion or Noise:

   • Verify that the input and output levels are within the acceptable range.
   • Use shielded cables to reduce interference.
   • Ensure proper grounding of all connected devices.

3. No Audio Output:

   • Check the connections to the output channels.
   • Verify that the correct output channel is selected in your audio software.
   • Ensure the device is powered on and initialized correctly.

4. Interference with Arduino Communication:

   • Use separate power supplies for the Arduino and the Dariyan-X 8ch if interference occurs.
   • Ensure the I2C address used in the code matches the device's address.

Q: Can the Dariyan-X 8ch be used with other microcontrollers besides Arduino UNO?
A: Yes, the device can be used with any microcontroller that supports I2C or USB communication.

Q: What is the maximum cable length for audio connections?
A: For best performance, keep cable lengths under 3 meters to minimize signal degradation.

Q: Does the device support phantom power for microphones?
A: No, the Dariyan-X 8ch does not provide phantom power. Use an external phantom power supply if required.

Q: Can I use the device for live audio streaming?
A: Yes, the Dariyan-X 8ch supports real-time audio processing, making it suitable for live streaming applications.
