CONNECTING TO THE AMPLIFIER
For bi-amping,
connect the
ampli
fi
er driving woofers
to
the poles +1 and -1, and the
ampli
fi
er
driving midrange &
treble drivers to poles +2 and -2.
For single wiring
, the plus wire from ampli
fi
er should be
connected to the both plus poles (+1 and +2) and the
minus wire similarly to the both minus poles (-1 and -2).
This goes easiest with a four pole cable (like Supra Rondo).
If a two pole cable is used, please c1 and +2 poles
together with a short piece of insulated wire to avoid short
circuit (-1 and -2 poles similarly).
In Both cases we recommend you to use high quality louds-
peaker cable of 1,5 - 4 square millimeters (12-16 Gauge).
