Aux port t o alignment t one headset w iring
A standard 32 ohms stereo headset can be connected to the Aux port to use the audio alignment tool. The
diagrams of the adapters for RJ45 and RJ12 are provided in Alignment Tone Cable and RJ12 Alignment
Tone Cable respectively. The recommended values for both resistors are 220 ohms, 0.25 W. Different
resistor values can be used to optimize the level of the audio signal depending on the headset
characteristics and the level of ambient noise.
