The pin configuration for all XLR connectors is:
Pin 1=Ground, Pin 2=High (+), Pin 3=Low (-)
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 input
There is one XLR connector for the fader line input. This balanced input will accept a +4dBu reference
signal. The XLR active-balanced input is suitable for any high level line source.
5. XLR Line output
There is one XLR connector for the fader line output. With a ba4dBu signal present at the line
input and the slide fader set to the “0” mark, the balanced XLR line output will be +4dBu.

Operation Section
NOTE - All active-balanced output circuits of the Fader 1 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.
