QUANTUM COMBOS
The four Quantum combo models’ identical
preamp sections sport an array of impressive
features. Fine-tuned for active and passive
basses, the audiophile input stage with its
vast gain range provides the underpinning for
the amps’ tremendous performance power.
Instant and musical tone-shaping control
comes courtesy of the parallel four-band EQ
section. With these no-nonsense tools, dialing
in the sound you want is dead easy. Punch
and HF Character switches are on board to
enhance your sound-sculpting pleasure. And
perhaps best of all, the nifty Tube Growl knob
controls tube saturation level, compressing
the signal and endowing it tube-driven punch
and assertiveness. Quantum Combos are
truly in a class of their own!
Dynavalve
®
Power Amp Technology
A genuine marvel of audio engineering,
our patented Dynavalve technology
delivers the highly desirable
transient response of all-
tube power amps. This
unique technology serves up
enormous pressure and punch
and makes Quantum amps
way superior to conventional
solid-state designs. How can
an amp conjure such heavy-
duty tube tone yet weigh
even less than comparable
solid-state designs? The secret
to this sonic sorcery is a single
tube in the phase splitter stage.
