5 CONNECTIONS AND SETTINGS
We suggest to use high quality wires, well protected, and balanced connections to avoid external EMD.
If ground loop problems are encountered, never disconnect the mains earth, but instead, try disconnecting
the signal screen on one end of each of the cables connecting the outputs of the Parrot to the loads. If such
measures are necessary, balanced operation is recommended.
5.1 AUDIO INPUT
The equipment features electronically balanced XLR female inputs (line level).
Pin 1 Gnd
Pin 2 Signal
Pin 3 Return
If no balanced connection is possible, please connect the cold pole (Pin 3) to the
ground (Pin 1). Factory preset input impedance is 10 kΩ. Input impedance of 600 Ω
is also available, simply setting jumpers on the rear I/O board (see next Section).
5.2 INPUT IMPEDANCE
At the delivery, input Impedance is set at 10 Kohm. The impedance may be set to 600 Ohm by moving the
jumpers located on the rear board (J2 and J3) close to the XLR input connectors, as shown in the following
figure:
