QUANTUM SERIES

Superior Bass Amplification

Gravity-defying groove monsters:

Light weight, sound great!

Amazingly light, every pound of a Quantum amp packs a very big punch. And with awesome tube tone to boot, they are engineered for instant gratification today and sustained satisfaction for many tomorrows to come. From the 250-watt QC 310 combo to the 600-watt flagship QT 600 head, these amps put many a heavyweight to shame! For the first time, our unique Dynavalve® power amp technology weds the warmth and expansive sound of traditional all-tube machines to the precision response of leading-edge solid-state amps. This ingen- iously engineered power amp circuit features a phase splitter tube, lending every amp its trademark tone and bright blue glow.

For a more profound musical experience, take the Quantum leap!

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.

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!
