XLR inputs and outputs
We used exclusively Switchcraft/Neutrik XLR input and output plugs to guarantee perfect
connectivity in the studio. They provide an optimal connection thanks to their electrome-
chanical design and large contact surface.
The image shows the XLR connectors pinout. They are balanced and have three conductors
or wires. Conductor 2 (Pin 2) corresponds to the (+) or hot Signal.
In case an unbalanced connection is necessary, the correct polarity of the conductors
needs to be observed.
Ground Lift switch to avoid ground loops
On the rear panel of the PASSEQ Mastering Equalizer (see page 10) is also a „GND LIFT“
(Ground Lift) switch to avoid any ground loops. Ground loops take place when gear con-
nected in the same network have different potentials.
The GND LIFT switch disconnects the equipment ground from the service ground to avoid
such problems. The Ground Lift function is activated (= equipment ground disconnected)
when the switch is depressed.
