User manual MARSHALL VALVETEST AVT150X

[. . . ] AdvancedValvestateTechnology AVT150X, AVT150HX & AVT275X 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. [. . . ] Gated Reverb: by `chopping-off' the end of the reverb's decay `tail' via a Noise Gate, this program is great for spicing-up chord stabs without cluttering up your sound. Chorus: splitting the signal and then mixing the dry signal with a detuned version creates this popular effect. To add to the subtle `widening' this creates, the detuned signal is modulated by an LFO (Low Frequency Oscillator) which causes the detuning to vary. The result is a subtle, lush sound that is equally effective on both clean and dirty tones. The delay time is adjustable in 10 millisecond (ms) increments and can be set to be as long as 1270ms which is well over 1 second. Chorus/Room: as the name suggests, this combines Chorus and a large room Reverb. Chorus/Delay/Room: if program 14 isn't dramatic enough for you then this is definitely the one for you, as it adds Delay to the Chorus & Reverb mix!Modulation: this effect is similar to the chorus effect but is less subtle and can be used to create rotary speaker-like effects. 23. DFX Mix Controls (Clean FX & Overdrive FX) These determine the level of the internal effects selected by the pair of Program controls (25). The top DFX Mix control works on the two OD channels while the bottom one works on the Acoustic Simulator and Clean channels. Digital FX Program/Adjust Table This lists the 16 programs selectable via the Program control (25) and also indicates which parameter the Adjust control (24) modifies for each one. Adjust Controls (Clean FX & Overdrive FX) For each of the 16 selectable DFX a particular parameter is adjustable. For example, when a Reverb is chosen, the decay (how long the reverb will be heard before it fades away) is adjustable via this control. The `Program/Adjust' table (26) on the front panel of your amp lists what the Adjust control does for each of the 16 programs. As was the case with the DFX Mix controls, the top Adjust control works for the two OD channels and the bottom one for the Clean & Acoustic Simulator channels. 25. Program (Clean FX & Overdrive FX) These select each one of the 16 on board digital effects - the top Program control works on the two OD channels and the bottom control works for the Clean and Acoustic Simulator Channels. The DFX available include single effects such as Reverb (9 types), Delay or Chorus and also multi-FX such as Chorus/Delay/Room. To add further to the flexibility of these two DFX sections, they can be switched on and off via the sturdy, LED foot-controller which comes supplied with each amp. 27. Advanced power amplifier muting circuitry provides anti-thump protection on power up and down. Important Note: As is the case with an all-valve amplifier, there will be no signal heard until the amp's ECC83 preamp valve warms-up and starts to pass signal. This can take up to 15 seconds so don't panic! 12 13 14 15 16 6 7 AVT150X & AVT150HX Rear Panel Features 1.
