[. . . ] Owner's Manual E1 Precautions Location Using the unit in the following locations can result in a malfunction. · In direct sunlight · Locations of extreme temperature or humidity · Excessively dusty or dirty locations · Locations of excessive vibration · Close to magnetic fields Power supply Please connect the designated AC/AC power supply to an AC outlet of the correct voltage. Do not connect it to an AC outlet of voltage other than that for which your unit is intended. Interference with other electrical devices Radios and televisions nearby may experience reception interference. Operate this unit at a suitable distance from radios and televisions. Handling To avoid breakage, do not apply excessive force to the switches or controls. Care If the exterior becomes dirty, wipe it with a clean, dry cloth. [. . . ] Anyway, call `em what you will, these wondrous glass bottles lie at the tonal heart of each of our 16 models. As all the amps we've modelled hail from one of the two countries just mentioned, in honour of their heritage, the descriptions of all English amps will employ the words "valve" and "valves, " while the American ones will be tubular!QUESTION: What's the difference between an ECC83 preamp valve and a 12AX7 preamp tube?They're the same exact thing ­ namely the most popular preamp tube in ampland. See, I told you we were two countries divided by a common language! Amp/Effect REVERB DELAY MODULATION PEDAL CABINET TYPE AMP TYPE Power Amp Accuracy What happens in the power stage of any good tube amp is of paramount importance to the way the amp sounds, feels and behaves. The way the power amp operates (Class A or Class AB), the power tubes used (EL84s, EL34s, 6L6s, 6V6s), the exact nature of the negative feedback loop circuitry (if one even exists) and how the power stage interacts (a relationship called damping) with the speaker(s) it is driving - all these things play a vital role in the creation of tone. That is why we have fitted your ToneLab with our patented Valve Reactor Technology ­ a modelling breakthrough that is unique to VOX and infuses our critically acclaimed Valvetronix range of amps with life and feel. This revolutionary technology emulates a tube power-amp by using real tubes in a real tube amp circuit and ensures that all the important bases inherent in a tube amp are faithfully and accurately covered. For example: if you choose amp model AC30TB - an amp with a Class A power stage, EL84 output tubes and no negative feedback, that's exactly what your Valve Reactor power amp reconfigures itself to be. This all said, let's take a look at each of our amp models. . . 1. AC15 This is modelled on Channel 2 of an amazing sounding 1962 VOX AC15, which is part of our vast amp collection. This 1x12", 15 Watt, valve driven, dual channel combo was unleashed on the market in 1958 and was the first ever VOX amplifier. The reason for it being named the AC15 is simple: AC stands for Amplifier Combination, while 15 indicates the Wattage. Thanks to its compactness, power, built in tremolo/vibrato effects (on Channel 1 only) and tremendous tone, this combo was a huge hit with the popular British guitar bands of the time, including several chart topping acts, the majority of whom were only too happy to endorse Vox. One of the biggest reasons for the unique, signature tone of this amp is the fact that it employs EL84 output valves in a Class A circuit with no negative feedback. This is also true of the other three VOX amps, we've modelled - the AC15TB, 23 AC30 and AC30TB. In a nutshell, the result of this design is more power and more distortion - the latter of which gets thick with second and third order harmonics that become more and more prevalent as the amp is cranked. Thanks to our unique Valve Reactor Technology the power stage of your ToneLab is automatically switched to its "EL84s in a Class A circuit with no feedback" emulation whenever AC15, or any of the other three Vox models, is chosen. Like most amps of its era, the AC15 is the very essence of simplicity. In fact, the Channel we modelled, Channel 2 (remember!?), only has three controls Volume, Brilliance (really a bass cut) and Top Cut. When you select AC15, the ToneLab's GAIN control mimics the original's Volume control, while the PRESENCE control acts as the Top Cut. * FYI, the AC15's Top Cut control affects the high frequencies in a very different way than a "regular" Treble control. Deft use of it will help you dial in the exact amount of that instantly recognizable, world-famous VOX "sparkle. " The BASS control acts as the Bass Cut (Originally labelled Brilliance) with total variability instead of the Original two position switch.

NOTE: Never turn off the power while this reload operation is occurring. Tuner Program List Spec.
