QUANTUM

Superior Bass AMPLIFICATION

SUPERIO

The sheer physical force of a lowfrequency impulse. The breathtaking warmth of a tube power amp. The ultra precise response of a high-endstudio device. In a nutshell, superior tone and touch are what Quantum™ bass amps are all about. Nothing less will do.

An unprecedented union of classic and innovative technologies has birthed a new breed of bass amp. And it brings a hitherto unimagined measure of musicality, tonal authority and portability to the working bassist.

THE DynavalveTM Power

amp Technology

Seasoned players know the deal: 100 tubedriven watts simply sound louder than 100 solid state-poweredwatts. The reason for this is that tube power amps’ complex dynamic properties enhance audio signals with transients. These added frequencies enrich the spectrum, making each note more concise, more explosive, and louder. Hence, signal content is decisive in determining the perceived volume, touch and response – the very “feel” of an amp.

Though tubes are influential, tube power amp circuits have a far more formative hand in shaping these audio phenomena. With this fact in mind, the engineers who masterminded the Quantum™ series created a 21st century original - the world’s first tubeless power amps with totally tube-drivenresponse. A quantum leap in performance, thepatent-applied-forDynavalve™ technology delivers better tone, greater sound pressure and a mightier punch to satisfy even the most discerning bass player.

The Preamp Technology

Quantum™ amps’ inputs feature the

Tube Touch Circuit™. Extraordinarily saturation-resistant, this circuit makes the amp remarkably responsive to the players’ touch.

Another wonderfully practical feature is the Tube Growl knob that serves to dial insweet-and-soulfulsounding compression and tube saturation effects.

It sweeps smoothly from subtle to strident

– and all points in between.

Functionality of conventional serial EQs

Functionality of the parallel EQ

A breed of EQ otherwise found exclusively in high-endstudio gear, thePure Parallel EQ™ dramatically reduces undesirable filter effects, turning thefour-bandvoicing section into an awesomely effective soundsculpting tool. Tweaked specifically for the bass, it affords easy, intuitive handling and transcendent audio results.

Enhanced HF Neodym

Speaker Technology

All Quantum™ combos and cabinets are loaded exclusively with speakers featuring Neodym magnets. Not only does this technology significantly reduce

weight, it also creates a more concentrated magnetic field that considerably enhances response.

These speakers feature integrated HF systems designed to render the crucial overtone spectrum with utmost uniformity. While the 10" speakers use parallel membranes (that is a dual cone design) to this end, the 12" and 15" woofers feature a fresh new technology. A machined aluminum cone (Dura Dome™) renders the voice coil’s high frequency output. Both of these technologies deliver true response, a wide pattern of throw, and a rich overtone spectrum that blends perfectly with the low and mid-frequenciesproduced by the main membrane.

Tuned ResonanceCabinet

Technology

Many years experience designing, tuning and manufacturing speaker enclosures enabled the Quantum™ development team to build cabinets that – like fine acoustic instruments - make the most of resonances. Ingeniously engineered panels and bracings, as well as the robust, six-plyOkumé wood (with about half the weight of standard cabinet woods), deliver powerful, punchylow-endprojection and finely balanced, crisp midrange. Because the resonant enclosure is tuned to radiate uniformly across its entire surface area, the bass signal can be localized precisely from any position on the stage.

QT 600

The toasty warmth, brawny punch and intuitive handling of a classic all-tubetone machine, wed to the flexibility and precision of a premium studio device: This combination of qualities makes the QT 600 the first choice for bassists who refuse to settle for anything less than the best.

The amp’s mighty heart is a powerhouse 600 watts Dynavalve™ amp. Pumping out ample power for persuasive performance in every sonic scenario, it offers plenty of headroom to stress even the most fulminate musical accents. TheTube Growl knob affords total control over typicaltube-drivencompression and saturation, and an impedance selector matches output power to suit connected cabinets.

The two passive and active inputs are extremely responsive across the full

sweep of the gain spectrum, providing the perfect platform for launching even the most propulsive grooves. Powered by sophisticated parallel EQ technology, the four-wayvoicing section spares the rod to “spoil” the signal, gently tweaking frequencies for the most effective and musicalsound-sculptingimaginable. Four pushbutton filters shape the basic tonal character: Punch emphasizes the low and high ends without altering level. Bass Shape attenuates the bottom end, say, to suppress undesirable stage rumble. Mid Boost pumps up the mids for muscular metal tone. HF Character underscores the shimmering overtones at the top of the frequency spectrum.

The QT 600’s DI Out balanced is variable, sending either the instrument’s (PRE) or the amp’s signal (POST) to the mixing console.

This latest-generationbass cabinet offerstop-draweraudio quality in an astonishingly light package.

Neodym speakers are the pumping heart of the new Quantum™ PRO cabinets. Developed in a joint effort with Eminence®, this technology delivers faster, more direct and precise response to the bassist’s touch for more controlled and musically expressive playing.

All speakers ship with onboard HF transducer systems: The Dual Cone (in 10" speakers) and DuraDome™ designs render overtone spectrums unrivalled in depth, breadth and congruity – sans the phase and directivity problems commonly encountered with horns.

Built to withstand the rigors of the road, Quantum™ PRO cabinets’ robust plywood, rugged steel grilles, Speakon connectors and Old World workmanship ensure years of dependable service for even the hardest-touringplayer.

Can a classic be improved upon? Certainly, as the QS 810 PRO attests! Sporting a brand new set of Neodym loudspeakers, this 8 x 10" cab sounds fatter, sleeker and fresher.

The compact alternative to the 8 x 10" bin: Its high-performanceNeodym speakers pack the powerful punch of a classic

8 x 10" cab into a far more portable bin.

A well-rounded,very musical soundscape with wondrously woody mids - this incredibly lighthigh-performancebin puts the joy back into and takes the pain out of bass stacks!

A state-of-the-art4 x 10" bass cab, it pumps out crisp, tight low end, finely textured mids, and - courtesy of its Dual Cone Neodym speakers - expansive, shimmering top end.

This ultra compact, extremely light powerhouse is the perfect complement to bigger bins and a sweet standalone solution that delivers professional-classtone for smaller gigs.

The perfect partner for the QS 410 PRO or QS 210 PRO: The earthy low end and woody mids of its 15" woofer meld with these models’ 10" speakers’ frequency spectrum to yield a homogenous and very musical sonic image.

Combos

Introducing a new class of bass combo, this line for the first time unites uncompromising sound quality, extraordinary headroom, intuitive handling and sensationally low weight.

The Quantum™ Combo series comprises four models sporting identical preamp sections featuring an audiophile input stage with a vast gain range for active and passive basses, a Punch button for accentuating low and high end response, and a highly efficient four-bandEQ.

HF Character is another special feature. When this dual-purposetreble knob is twisted to the right, it gradually dials inhigh-frequencysparkle; to the left, it works like a classic treble pot. TheTube Growl knob controls the level of tube saturation, which serves to compress the signal and lend ittube-drivenpunch and assertiveness.

The rich, fat fundamental sound of the Quantum™ Combo is powered by Dynavalve™ technology. This brilliant

power amp circuit’s phase splitter tube is visible in a bright blue glowing window on the control panel.

Cordura bags with a pull-outhandle and casters are available as optional accessories for all Quantum™ Combos.
