The SSW-351 contains a built-in crossover network.
There are several ways in which an additional speaker can be connected to the SSW-351.
Since the HIGH FREQ OUTPUT is routed
through the internal crossover network,
a signal from which the low range has
been cut will be sent to the connected
speaker.

The PARALLEL INPUTS can be used as an

a full range speaker. A full frequency
range signal will be sent to the
connected speaker.

The speakers can be driven by multiple
amps very simply with the internal
crossover network. When driving the
speakers with two power amps (bi-
amping), connect the speakers using the
parallel input jacks.

If you wish to use an external channel
divider (crossover network) instead of
using the built-in crossover network,
make connections to the DIRECT INPUT.
Pay attention to the crossover frequency
