ISP Technologies VECTOR - Manual (Page 3)

VECTOR CONCEPT
The VECTOR 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,
as you would for any other speaker cabinet, and get ready to unleash the most
unbelievable low-end punch and bass performance you have ever heard. The
internal amplifier of the THETA head drives the two twelve inch guitar speakers
directly 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 cabinet. The
internal 400-WATT RMS Active 15-inch subwoofer delivers more deep, low-end
punch than any other guitar cabinet available. The VECTOR ACTIVE cabinet is
high on innovation, incorporating novel Line Array geometry and the patent
pending Dynamic Current Amplifier Technology “D-CAT” powering a 500-watt,
4-inch voice coil, 15” woofer. With two 12” guitar speakers in vertical Line
Array geometry, ISP solves the problem of horizontal dispersion. Not only does
a typical 4x12 guitar cabinet deliver poor bass response but the high frequency
response also beams like a flashlight. Directly in front, your ears get shredded
yet, move slightly off center and you lose all the high frequencies. The
VECTOR cabinet solves this problem through use of Line Array geometry
providing excellent off axis dispersion at the higher frequencies. The VECTOR
Cabinet is flat all the way down to 50Hz 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 continues to perform. The VECTOR cabinet can also be
used with any existing amplifier. To all this performance, add three-way power
amplifier protection and you have the most reliable active guitar system ever
made. The VECTOR’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, 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 delivers a level of
performance never before available.
