The SPL 1:2 is a signal level splitter designed to divide an input signal into two equal output signals. It is commonly used in audio and video applications to distribute signals to multiple devices without significant loss in quality or strength. This component ensures that the original signal integrity is maintained while providing a reliable and efficient way to share signals across multiple outputs.
The SPL 1:2 is designed to handle a wide range of signal types while maintaining high fidelity. Below are the key technical details:
Parameter | Value |
---|---|
Input Signal Type | Analog or Digital |
Frequency Range | 20 Hz to 20 kHz (audio) |
Input Impedance | 10 kΩ |
Output Impedance | 1 kΩ |
Voltage Range | 0.5 V to 5 V (peak-to-peak) |
Power Supply Voltage | 5 V to 12 V DC |
Power Consumption | < 100 mW |
Signal Loss | < 0.1 dB |
The SPL 1:2 typically comes with a 5-pin interface for input, output, and power connections. Below is the pinout:
Pin Number | Name | Description |
---|---|---|
1 | VCC | Power supply input (5 V to 12 V DC) |
2 | GND | Ground connection |
3 | IN | Signal input |
4 | OUT1 | First signal output |
5 | OUT2 | Second signal output |
While the SPL 1:2 is not directly programmable, it can be used in conjunction with an Arduino UNO to monitor or control the signal distribution. Below is an example of how to monitor the input signal voltage using the Arduino's analog input:
// Example code to monitor the input signal voltage of SPL 1:2
// Connect the IN pin of SPL 1:2 to Arduino's A0 pin for monitoring
const int signalPin = A0; // Analog pin connected to SPL 1:2 IN pin
void setup() {
Serial.begin(9600); // Initialize serial communication at 9600 baud
pinMode(signalPin, INPUT); // Set the signal pin as input
}
void loop() {
int signalValue = analogRead(signalPin); // Read the analog signal
float voltage = (signalValue / 1023.0) * 5.0; // Convert to voltage (0-5V range)
// Print the voltage to the Serial Monitor
Serial.print("Signal Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(500); // Wait for 500ms before the next reading
}

Q: Can the SPL 1:2 handle digital signals?
A: Yes, the SPL 1:2 can handle both analog and digital signals, provided they are within the specified voltage and frequency range.
Q: Is the SPL 1:2 suitable for high-frequency applications?
A: The SPL 1:2 is optimized for audio frequencies (20 Hz to 20 kHz). For higher frequencies, ensure the component's specifications meet your requirements.
Q: Can I use the SPL 1:2 without a power supply?
A: No, the SPL 1:2 requires a DC power supply (5 V to 12 V) to operate.
Q: How do I test if the SPL 1:2 is working correctly?
A: Use an oscilloscope or multimeter to measure the input and output signals. The output signals should match the input signal in amplitude and frequency.
