User manual HUGHES & KETTNER QUANTUM

[. . . ] In a nutshell, superior tone and touch are what QuantumTM bass amps are all about. 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. R Technol THE DynavalveTM Power amp Technology Seasoned players know the deal: 100 tubedriven watts simply sound louder than 100 solid state-powered watts. The reason for this is that tube power amps' complex dynamic properties enhance audio signals with transients. [. . . ] A machined aluminum cone (Dura DomeTM) 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-frequencies produced by the main membrane. Tuned ResonanceTMCabinet Technology Many years experience designing, tuning and manufacturing speaker enclosures enabled the QuantumTM 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-ply Okumé wood (with about half the weight of standard cabinet woods), deliver powerful, punchy low-end projection 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. 15" duraDomeTM Neodymium SPEAKER HEAD QT 600 The toasty warmth, brawny punch and intuitive handling of a classic all-tube tone 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 DynavalveTM 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. The Tube Growl knob affords total control over typical tube-driven compression 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-way voicing section spares the rod to "spoil" the signal, gently tweaking frequencies for the most effective and musical sound-sculpting imaginable. 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. · 600 watts · 14, 5 kg/32 lbs · 2. 8-16 ohms Power x TonE / Weight This latest-generation bass cabinet offers top-drawer audio quality in an astonishingly light package. Neodym speakers are the pumping heart of the new QuantumTM 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 DuraDomeTM 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, QuantumTM PRO cabinets' robust plywood, rugged steel grilles, Speakon connectors and Old World workmanship ensure years of dependable service for even the hardest-touring player. Qs 81o PRO Can a classic be improved upon? [. . . ] Its 12" Neodym woofer weds the hairtrigger response of a 10" speaker to the beefy punch of bigger membranes. Even in loud bands, it lends bass signals plenty of oomph to cut through. · 400 watts DynavalveTM Power Amp · 1 x 12" DuraDome Neodym Speaker · Parallel EQ · Effects Loop · Headphones Out · 20 kg/41 lbs QC 415 The big bark of a classic 15" combo, the assertive bite of a stack, and the light weight of a practice rig - QC 415 is the new benchmark for every bass-slinging scenario. · 400 watts DynavalveTM Power Amp · 1 x 15" DuraDome Neodym Speaker · Parallel EQ · Effects Loop · Headphones Out · 24 kg/53 lbs QC 421 The loudest, punchiest and most versatile QuantumTM Combo: From classic picked rock riffs to stinging slap attack and smooth walking jazz bass, the QC 421 does it all with amazing aplomb.
