14. e Audio Inputs Since the audio inputs are unbalanced single ended the ground reference of the source has to be the same as the matrix Of course the cable connecting the two is tying the grounds across but if there are currents flowing in the ground it can create potential differences that would manifest as noise The quality of grounding at the audio source and the matrix are important For example if the input source is a desktop PC as long as the PC is properly grounded and the audio cable length is not excessive you can expect good results On the other hand if the input is a notebook PC running on battery there is no ground reference at the source so it gets its reference through the audio and video cable connection to the matrix This should also be okay However if it is plugged in through its external power brick noise can be induced This is because most notebook power supplies do not properly provide an AC ground path to the system ground some only have only 2 prong AC cords The switching power supply circuit will inject noise into the audio lines In this case the solution may be to attach a low resistance ground strap to the notebook The other option for eliminating the noise is to use a stereo audio Balun or isolator The Balun essentially couples the audio through a transformer so the audio grounds are isolated Baluns can also cure noise pickup in long cable runs 2 2 Output Audio amp Video Connections Figure 3
