Intel Peavey ReValver MK III - Manual (Page 36)

Tweaking modules
One of the most powerful features of ReValver® MK III is the ability to tweak each parameter of a module
other than the usual knobs and buttons on the front of the module. In an effort to explain the Tweak
mode in ReValver, we’ve written some short explanations of each tweak in the tube tweak GUI.
TheTweak mode in ReValver was written on an engineering level using real schematics by a real tube
amplifier company, and it takes years to learn tube amplifier engineering, so the awesome “tweakability”
of ReValver MKIII will keep even the most experienced valve amplifier engineer busy for hours. Users who
don’t have any experience with tube amps will have fun, and you’ll learn a lot about how tube amplifiers
work.
Press the “+” butt on on the module, or select “Tweak Module” on the module menu to bring up the
general Tweak GUI. The Tweak GUI is a general GUI that holds specialized tweakable components that
differ from module to module. Some features include Frequency Analyzer, Oscilloscope, Total Harmonic
Distortion analysis and save Impulse Response.
The Frequency Analyzer runs a frequency response test of the module in question. It does so by
inserting a short “pulse” and performing a FFT (Fast Fourier Transform) frequency analysis of the
out put. Please note that such techniques may not yield expected results in non-linear modules
such as distortion modules. The Frequency Analyzer also accurately displays the phase response
of the module. The analyzer window is displayed in logarithmic mode with the lower frequency
shown in high resolution. This emphasis can be adjusted via the slider at the bottom of the win-
dow.
