(18) OUT 3
XLR output for balanced power amplifiers. 1 = ground, 2 = posi-
tive, 3 = negative ground lift XLR. With the ground lift, the XLR
outputs can be isolated from the signal ground for the preampli-
fier. Setting O corresponds to the ground isolation. In setting I,
the ground of the XLR outputs over 3.3 ohms is connected to the
preamplifier ground. Isolating the ground is useful when multiple
devices in the system have a power supply with a three-pin
grounding plug to prevent ground loops.
