3. Power Inlet
The cable from the PS4-F power module connects to this 4 pin square connector. This connector and its
respective plug are keyed so they will only fit in one direction. For power module installation
instructions, refer to the Installation Section on page 4 of this manual.
As shown in the connector illustration “Power Inlet Pins” the 16VAC from the external power module is
connected between pin 1 and pin 2.
4. XLR Line inputs
There are two XLR connectors for the fader line inputs. These balanced inputs will accept a +4dBu
reference signal.
The XLR active-balanced inputs are suitable for any high level line source.
5. XLR Line outputs
There are two XLR connectors for the fader line output. With a ba4dBu signal present at the line
inputs and the slide fader set to the “0” mark, the balanced XLR line outputs will be +4dBu.

NOTE - All active-balanced output circuits of the Fader 2 were designed for balanced lines and
should only be connected to balanced inputs. If that is not possible and it is necessary to
connect to an unbalanced input, care must be taken not to connect the low (-) terminal
to ground. If the low (-) terminal of these outputs is connected to ground, the result may
be a high level of audio distortion.
