Unbalanced inputs
: Connect the
conductors to the connector as
shown. Make sure that the unused
side of the balanced input is
connected to ground, as shown.

XLR Connectors:
Each channel has active balanced "Euro-style" terminal block and
XLR input jacks wired in parallel. The input impedance is 20k
ohm balanced or 10 k ohm unbalanced. Unused input jacks may
be daisy chained to additional amplifiers.
Balanced connection is recommended. Balanced signals are less
prone to AC hum and other electrical noise. Unbalanced signals
can be suitable for short cable runs. The signal source's output
impedance should be less than 600 Ohms to avoid high fre-
quency loss in long cables.
If the DataPort V2 is being used for the input signal source, the
XLR and terminal block connections should not be used for
inputs. However, they may be used for daisy chaining the
DataPort V2 input signal to other amplifiers. The signal available
from the XLR and terminal block connections will be about 10 dB
lower than the DataPort V2 signal.
