[. . . ] AdvancedValvestateTechnology AVT20X, AVT50X & AVT50HX Owners Manual ENGLISH From Jim Marshall I would like to thank you personally for selecting one of our Valvestate AVT amplifiers. Ever since its initial launch in the early 1990's, the original Marshall Valvestate technology received worldwide acclaim and set a new standard in affordable quality amplification. However, my dedicated team of designers are constantly looking for methods to make our amplifiers sound even better. As they are all guitar players themselves this process has become a passion within the design department. [. . . ] Due to the remarkable realism of our Advanced Valvestate Technology, once the Volume control is turnedup past a certain point, the preamp will start to push the power amp section into creating its 7. CD Input Jack Socket The CD input will take a stereo signal from an external source, such as a CD or tape player, and mix it into a mono format. Because this input is after the preamp stage, its volume has to be controlled from your CD or tape player. 2 3 8. Emulated DI Out Jack Socket This jack socket carries a specially treated output signal from your AVT20X which accurately emulates the sonic signature of a guitar loudspeaker. This output can be used in both live performance and recording situations to achieve authentic guitar amp tones without having to use a microphone. Furthermore, if you wish to mute the loudspeaker, for `silent' recording, then merely insert an unused jack plug (a short patch cable will do fine) or a set of headphones into the Headphone socket. 9. Headphone Jack Socket In addition to providing a specially filtered output signal for a set of headphones, this jack also disconnects the main loudspeaker, enabling you to practice in `silence'. 5. Channel Push-switch Your AVT50X has two channels - Clean and Overdrive. This switch selects the channel you desire - `out' for Clean and `in' for Overdrive. When using the supplied footswitch, the channel push-switch must be left in the `in' position for the footswitch to operate. The Clean channel of the AVT50X has the warm, responsive action normally associated with a valve amp, rather than the relatively sterile, one-dimensional sound that is typical of many solid-state type guitar amps. At lower Gain settings this channel remains very clean but will evolve into bluesy/rock type crunch at higher Gain settings. When the Overdrive channel is selected it will take you from mild crunch to aggressive `modern' distortions and all-points in between. The many sonic palettes available from both channels are dependent on the exact settings you choose on the front panel controls for Gain, Volume and EQ. 10. External Speaker Jack Socket This socket allows you to connect your AVT20X into an external loudspeaker system, provided it has an impedance of 8 or 16 ohms. By using any one of our comprehensive range of extension cabinets, you will be able to unleash the massive amount of tonal options that extra loudspeakers will provide. designed to achieve maximum tonal variation from your AVT50X and, just like our famous allvalve amps, are highly inter-dependent on each other. As a result, the way each one functions depends on the exact position of the other two controls. This is especially true of the Bass and Treble controls in relation to the Middle control. The lower the Middle control, the more reaction can be obtained from the others. As tone is very much down to personal taste, experimentation and experience is probably the best way of learning how these three controls will affect your sound. Some suggested settings are shown later. ENGLISH ENGLISH * Points to remember are: A) The tone and output level coming out of the guitar is as widely variable as there are guitars themselves, guitars are not designed (nor intended) to be equal. Therefore, amp settings will vary to suit your guitar and playing style, and, by necessity, are at your discretion. [. . . ] ENGLISH ENGLISH Blues Clean Here the preamp Gain is increased and what you start to hear is pure, harmonically rich break-up and compression from the internal Marshall ECC83. Again the neck pick up on a single coil guitar or the neck / bridge combination on a humbucker-loaded guitar will deliver the warmest tones. 2. Loudspeaker Jack Socket i. Combo Version (AVT50X) This socket allows you to connect your AVT50X into an external loudspeaker system, provided it has an impedance of 8 or 16 ohms. By using any one of our comprehensive range of extension cabinets, you will be able to unleash the massive amount of tonal options that extra loudspeakers will provide. [. . . ]
