Terminating the speaker cable

To terminate the cable, strip the end of the cable 0.2 inch (5 mm) and secure the

wires into the supplied 4-pole captive screw connector.

Speaker Conﬁguration

When setting up a speaker conﬁguration, the correct speaker impedance loading

must be observed.

By default, the ampliﬁer is set for dual mono output. Use the Extron software or SIS (Extron

Special Instruction Set) commands to change the setting to stereo if desired.
