Frequencies lying above the TREBLE control range’s center frequency are dampened, which emphasizes the character of this voicing control. Pushing the PUNCH button clearly enhances the HF-CHARACTER knob’s effect. The illustration shows the curves for PRESENCE (top curve) and TREBLE (bottom curve) at extreme HF-CHARACTER knob settings. ENGLISH 3. Tube Growl 3.1 Tube Saturation & Compression More than merely a means to determine saturation levels, the TUBE GROWL knob is a complex circuit that controls peaks like a tube preamp does, converting the energy of spikes into overtones rather than allowing it to dissipate. TUBE GROWL is comparable to a string that generates a fundamental frequency and a series of harmonics generated by half the string, a third, a quarter and so forth. The relative levels of harmonics are decisive in shaping tone, so it takes the right mix to please the human ear. The figure shows the harmonic overtone spectrum generated for a fundamental tone of 500 hertz. Serving to harness distortion is an intelligent compressor that grants you precision control over tube saturation. It keeps your string attack up front without undesirable spikes in volume, while avoiding all the pitfalls of conventional compressors. This circuit does not mask attack, generate pumping sounds, or any other sonic side effects. But it does deliver truckloads of sustain, making your instrument easier and more fun to play. 3.2 Handling: Tube Growl: The TUBE GROWL knob is a particularly handy feature, allowing you dial in natural compression and tube effects: This tool puts at your fingertips the means to control the compressor parameters threshold, ratio, make-up gain, and attack and release, as well as tube saturation levels. QuantumTM-combo Manual 4 Power Amp 4.1 Dynavalve™ Technology Seasoned players know the deal: 100 tube-driven 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. These added frequencies enrich the spectrum, making each note sound more concise, more explosive, and louder. In other words, our perception of volume is shaped not only by pure output power; the content of the signal is equally important. Though the musical qualities of tube-driven power amps are heartwarming, their weight-related drawbacks are backbreaking and budget-busting. Due to the nature of tube designs, they are bigger, heavier, more expensive and more sensitive than their solid state kin. The ideal solution would be a solid state power amp with the dynamic, frequency-enriching qualities of tube circuitry. And that’s exactly what Dynavalve™ technology is all about. It is the product of many years spent researching tube power amps’ tone-shaping processes. Rather than coloring the sound of a solid state amp, the Dynavalve™ circuit "forces" the amp to behave just like its tube-driven counterpart. The result: In comparison to conventional solid state power amps with the same power ratings, Dynavalve™ yields far better tone, much more sound pressure and greater punch! In a nutshell, Dynavalve™ delivers truckloads of tone, satisfying the demands of even the hardest-core tube fanatic. 4.2 Handling: Master: Though the MASTER knob determines the amp’s overall level, it is more than merely a volume knob. In combination with the GAIN knob, it lets you dial in subtle tonal variations to shape a vast spectrum of sound ranging from squeaky clean to true grit.

Further Connections 5.1 Fx Loop The FX LOOP is a serial circuit, meaning that effect devices are inserted serially into the signal path. This loop is located post TUBE GROWL knob and pre LINE OUT. In other words, LINE OUT sends a wet or processed signal. Note that you must set the desired dryto- wet balance on the effect device because in a serial loop like this, the entire signal is patched through the effect device. The FX LOOP is footswitchable (Hughes & Kettner® FS 2). Send: Connect this output to the input of your effects device. Return: Connect the output of your effects device to this input. 5.2 Line Out: The wet (or processed) preamp signal is patched out via this unbalanced line output. Located pre Dynavalve™ power amp, it is independent of MASTER knob setting. Note: Signals sent via this output are not colored by the sound of the Dynavalve™ power amp, so this is the output to use when you want to route the signal to another power amp or an auxiliary rig. 5.3 Di Out: With the speaker providing the source signal, this direct out sends a balanced, hum-free and frequency-corrected version of the amp’s output signal to the mixer. Because the circuit is post MASTER knob, its signal is shaped by the reciprocal action of speakers and ...
