BI-WIRE CONNECTION:
The S3900 connection assembly has two sets of input connectors that are connected by jumper bars. The upper set
of connectors is for the high-frequency/ultrahigh-frequency drivers, and the lower set of connectors is for the woofers.
This arrangement allows you to bi-wire the speakers using a single stereo power amplifier or to bi-amp the speakers
using two stereo power amplifiers. Bi-wiring and bi-amping can offer performance advantages and more flexibility in
power-amplifier selection over a conventional single-wire connection.
