User manual MARSHALL VALVETEST AVT100X

[. . . ] AdvancedValvestateTechnology AVT100X 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. [. . . ] The higher settings of the OD2 gain control can be likened to driving the front-end of an already raging Marshall valve amp with a high gain, overdrive stomp box. If you've already experienced the tonal pleasure of `front ending' a Marshall valve amplifier in this way, you will appreciate the energy and dynamics of this type of set-up!Turning the OD2 Gain control clockwise will see more of the already smouldering signal being sweetly compressed and `rounded' by the unique characteristic of the AVT's Valve Drive stage as it is driven over the top into total saturation. This channel can also be as nasty and `in-yer-face' as you would like. Engaging the OD2 `Scoop' button (13) will take this channel onto a new level of cranium crushing crunch, perfect for modern (a. k. a. OD1 Gain Control This rotary control can be best described as the `sonic brain' of the OD1 channel. Lower Gain settings will produce well-defined, natural sounding overdrives which have a nice `cut, ' making them perfect for funky, blues rock. Higher gain settings will see the sound start to get more `rounded' as the AVT's pre-amp valve is pushed into saturation. 18. FX Loop Mix Control (Clean & Overdrive) When an effects unit is hooked-up to the aforementioned FX loop, this control adjusts the FX Mix for all three channels. Turning it clockwise increases the amount of effect you hear - from `dry' (0) to `wet' (10). Please note that the FX mix on your external processor should be set to maximum (i. e. The Master Section These controls adjust the power amp section of your AVT and determine the overall Volume and Presence of the amplifier. 16. Master Volume Once you have set the relative volumes of your AVT's channels, this control governs the overall volume of the amplifier. 9. OD1 Scoop Switch Fine tuned to create the most awesome mid `scoop' imaginable, OD1's Scoop circuitry is more than just a pre-set middle control. Instead it actually reconfigures the whole post-EQ voicing of the channel - from low to high. Because of this, even though the resulting `scooped' sound that occurs when the switch is activated (pushed `in') is totally extreme, the channel's overall tone still remains tight and focused. B. Internal Digital FX As mentioned in the introduction of this manual, the AVT100X features a DFX (Digital Effects) section which adds digital effects to all three channels. The DFX section boasts 16 on-board effects and three controls - DFX Mix, Adjust and Program. We chose these particular effects algorithms to give you a comprehensive palette of natural sounding options. Overdrive Tone Controls Your AVT is equipped with rotary Bass, Middle, and Treble EQ controls which are shared between the two Overdrive Channels, OD1 and OD2. This EQ section boasts a tone circuit identical to the one used in legendary Marshall 4 5 The first 10 programs offered are all Reverbs. Reverberation effects recreate the natural echo reflections found in physical environments such as halls and rooms or, in the case of plate reverbs, a mechanically vibrating metal plate. [. . . ] 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 Sockets There is one speaker jacksocket on the AVT100X, marked Internal (8 Ohm), this is where the output of the AVT power amplifier is connected to its internal 8 Ohm Celestion loudspeaker. 7. FX Level This should be set to match the level of the processor being used (generally -10dB for a stomp box, +4dB for a professional, rack unit). Jazz Clean A warm rounded clean ideal for `comping' and walking bass progressions. Brit Crunch ! 8. FX Send WARNING: For connection to the input of the external device being used. Always provide the AVT100X with a load equal to, or greater than, 8 Ohms. * FX Loop Hints 3. [. . . ]
