Terminate The Speaker Cables From The Pvca 452 Amplifier - Extron electronics PlenumVault Installation Manual

3. Terminate the Speaker Cables from the
PVCA 452 Amplifier.
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 (see
image at right).
ATTENTION:
• DO NOT short the speaker wires together
as it may damage the controller amplifier.
• NE créez PAS de court-circuit entre
les fils de l'enceinte ; vous risqueriez
d'endommager l'amplificateur/contrôleur.
NOTE: The correct speaker impedance loading
must be observed when setting up a speaker
system. See images below for examples.
