Single-ended (SE) power output stages are probably the simplest form of power amplifier design and usually used for relatively small amplifiers, e.g., less than 15W. SE can only operate cleanly in Class A mode and produce an output rich in even harmonic distortion.
The T-USB interface supplies both a dry signal and the processed signal – split left and right to your DAW – directly into either your PC/MAC or iPad*.
In order to let you operate your tube amplifier silently we have included an internal dummy load. This means that you can use your amplifier without the need to connect an external load (speaker) to it, without fear of damaging your amplifier.
