Note: Shell Ground tab on XLR connectors is usually tied to ground at pin 1.
Choosing a Cable:
For unbalanced connections, use a good quality metal braid screened cable with two inner
wire cores; this will usually be clearly marketed as pro audio/microphone signal cable.
For long cable runs in excess of 6m/20ft, try to use cables with lower capacitance ratings, to
minimise any loss of sound quality. Keep cable runs short where possible, however be sure allow
a little bit of slack in the length of cable used to make the lead. Stretched, overstressed cables
tend to break at the most inconvenient moments
