Voxengo Tube Amp User Guide
Introduction
Tube Amp is an audio effect plug-in for professional music production applications
that applies asymmetric tube triode overdrive usually found in single-tube
microphone pre-amp boxes. The sound this plug-in produces varies from a mild
“warm” overdrive to a fuzzy distortion.
Tube Amp also includes a -6 dB/oct low-pass filter that is built-in into plug-in’s
tube/valve modeling equation, and can be used to imitate a lower-quality tube triode.
Beside that, Tube Amp has a switchable output saturation stage which can be used to
additionally overdrive the output signal.
Tube Amp features all standard advanced Voxengo plug-in features like full multichannel operation, channel routing, built-in oversampling and other functions.

Compatibility
This audio plug-in can be loaded into any audio host application that conforms to the
AAX, AudioUnit, VST or VST3 plug-in specification.
This plug-in is compatible with Windows (32- and 64-bit Windows XP, Vista, 7, 8, 10
and later versions) and macOS (10.7 and later versions, 64-bit Intel processor-based)
computers (2.5 GHz dual-core or faster processor with at least 4 GB of system RAM,
SSE4.2 instructions support required, e.g. any Intel Core i-, AMD Bulldozer- or Zenbased processor). A separate binary distribution file is available for each target

User Interface Elements
Note: Most interface elements (buttons, labels) located on the top of the user
interface and on the bottom are standard among all Voxengo plug-ins and do not
require much learning effort. For an in-depth description of these and other
standard user interface elements and features please refer to the “Voxengo Primary
User Guide”. Learned once it will allow you to feel comfortable with all pro audio
plug-ins from Voxengo.
Parameters
The “Mode” parameter selects processing mode. While “Mode 1” is mostly suitable
for moderate saturation only, “Mode 2” can be used to produce a very strong
distortion, suitable for guitar overdrive processing.
The “Drive” parameter specifies overall tube amp gain setting (in decibel).
The “Bias” parameter adjusts tube amp’s grid bias providing a mean to control
proximity of the half-wave to the tube triode’s cutoff point (parameter is defined in
percent).
The “LP Freq” parameter controls low-pass filter’s corner frequency (in Hertz).
Output
The “Out Gain” parameter adjusts the overall output gain of the plug-in (in decibel).
