You can drive unbalanced loads with the 565E’s outputs by using the XLR connector with pin 3
left open. In an emergency (the show must go on), you can ground pin 3, but if you have the
choice...leave it open. If you must ground pin 3, it is must be grounded at the 565E, rather than at
the other end of the cable. The price, regardless of whether or not pin 3 is grounded is 6 dB less
output level. If your system is wired with pin 3 hot, and you are driving an unbalanced load, pin 2
must float .
The 1/4-inch input jack is paralleled with the XLR-input. In a large installation, it is permissible to
use one of the connectors as the input connection and to use either or both of the remaining
connections for paralleling other inputs with the 565E.
The 1/4-inch output jack is a TRS (tip-ring-sleeve) jack wired for balanced operations. This jack may
also be used for unbalanced operation. The unbalanced output is always 6 dB lower in level than the
balanced output.
