VECTOR CABINET CONNECTIONS
Connect the VECTOR cabinet as shown above. Connect the speaker output of
the guitar amplifier to the input of the VECTOR cabinet using a speaker cable
with a ¼-inch jack connectors. Connect the IEC power cord to a proper AC
supply wall outlet using the power cable supplied with the VECTOR cabinet.
Turn on the guitar amplifier and then the VECTOR cabinet. Start with the SUB
LEVEL control on the VECTOR amplifier at the full counterclockwise setting and
increase the SUB LEVEL until the desired amount of bass is achieved.
Note: If you purchased the Vector Active Cabinet w/Celestion Vintage 30 12”
speakers, you will notice that a high resonance occurs when increasing the SUB
LEVEL on the back of the cabinet. This is normal operation because the
speakers’ sensitivity level is higher then that of the standard 12” speakers that
come with the Vector cabinet. When the head is powered on, the resonance
will cease.
