6. SINGLE-AMPLIFIER DRIVE AND BI-AMPLIFIER DRIVE
The SR-S4 series speakers are factory-preset to be driven by a single amplifier, however this setting can be
changed to a bi-amplifier drive system by changing the speaker's internal wiring.
(See p. 12; Changing Single-Amplifier Drive to Bi-Amplifier Drive System.)

7. INTERNAL WIRING DIAGRAM
When shipped from the factory, the speaker is internally connected as shown below.
• Since the Neutrik NL4MP connectors and screw terminals are internally connected in parallel, either one can
be used for connection.
• The Neutrik NL4MP connector's pins are wired
as shown at right.
The connector (connection cable side) suited to
the Neutrik NL4MP is the Neutrik NL4FC.
