1.Signal Direction: A 3.5mm to split RCA adapter is specifically designed to transmit audio signals from a 3.5mm source (like a smartphone or laptop) to two RCA devices (like speakers or amplifiers). The adapter carries the audio signal from the 3.5mm jack and splits it into two RCA outputs (left and right channel).
2.Input and Output: When connecting your devices, the 3.5mm jack is typically the input, while the RCA connectors are the output. Reversing the connection means the RCA connectors become the input and the 3.5mm jack becomes the output, which is not the intended functionality.
3.Impedance Mismatch: Audio devices have specific impedance levels, which affect the signal strength and overall audio quality. The impedance mismatch between the RCA output of your headphones and the 3.5mm input of the adapter can lead to signal degradation, noise, or distortion.
Connecting your device in this way may not only provide you with the desired audio conversion, but it may also adversely affect the audio signal's quality and potentially damage your equipment.
If you want to use your headphones with an RCA output, consider an adapter specifically designed for this purpose, such as an RCA to 3.5mm female adapter.
