Balanced XLR inputs and current source output connections

If your preamplifier has XLR outputs, it

can be connected to the XLR inputs as
shown. This diagram also shows the current
source output connections to the speaker
inputs. (The voltage source outputs can be
used instead, as shown on the previous
page).
