VECTOR SL CONCEPT
The VECTOR SL was designed for ease of use; simply connect the speaker
output of the THETA HEAD, or any other guitar amplifier, to the input of the
VECTOR SL like you would any other speaker cabinet. Connect your favorite
speaker cab to the external output, set the impedance switch to the impedance
of your cabinet, and get ready to unleash the most unbelievable low-end punch
and bass performance you have ever heard in a guitar system. The internal
amplifier of the THETA head or other guitar amp drives the external speakers
directly after being high passed by the VECTOR SL and simultaneously delivers
the input signal for the internal power amplifier that drives the internal active
subwoofer. The subwoofer level is adjustable via the sub level control on the
back of the VECTOR SL cabinet. The internal 600-WATT RMS Active 15-inch
subwoofer delivers deeper, low-end punch than any other guitar cabinet
available. The VECTOR SL Cabinet is flat all the way down to 45Hz delivering
enough low-end bass to match the frequency response of any 7-string guitar.
Tune down as far as you want and the VECTOR SL continues to perform. To all
this performance add three-way power amplifier protection and you have the
most reliable active guitar system ever made. The VECTOR SL’s internal D-CAT
amplifier has global thermal protection, thermal protection built in the power
transformer, and an on board distortion limiter circuit to eliminate the possibility
of feeding square waves to the woofer. This means that, as long and hard as
you drive the VECTOR SL, even to its maximum limits, you never have to worry
about failures. Whether you use the THETA head or any other guitar amplifier
the VECTOR SL delivers a level of performance never before available.
