CONNECTIONS
CAUTION: Make sure that all of the system's electrical components are turned OFF (and preferably
unplugged from their AC outlets) before making any connections.
Speakers and amplifiers have corresponding positive and negative ("+" and "–") connectors. The S3900 has two sets
of connectors; jumper bars connect the connectors to each other. The connectors are marked "+" and "–." Additionally,
the "+" connectors have red rings, while the "–" connectors have black rings. See the illustration below.
We have designed the S3900 so that a positive voltage at the "+" (red) connector will cause the speaker transducers to
move outward (toward the room).
We recommend using a high-quality speaker wire with polarity coding. The side of the wire with a ridge or other coding
is usually considered positive polarity ("+").
To ensure proper polarity, connect the left- and right-channel "+" connectors on the back of the amplifier or receiver
to their respective "+" (red) connectors on the speakers. Connect the "–" (black) connectors in a similar way. See the
owner's manual of your receiver or amplifier to confirm its connection procedures.
BASIC SINGLE-WIRE CONNECTION:
Connect the amplifier to each speaker as shown in the illustration below. You can use either set of connectors on
the speaker. NOTE: Do not remove the jumper bars from between the two sets of connectors when connecting the
speaker wires.

IMPORTANT: Do not reverse polarities (i.e., "+" to "–" or "–" to "+") when making connections. Doing so will cause
poor stereo imaging and diminished bass performance.
The S3900's gold-plated speaker connectors can accept a variety of wire-connector types: bare wire, spade
connectors, pin connectors and banana connectors.
