HE OWER AMP AND THE LORY
The Valve Reactor circuitry in the SV-1 has been tuned-up especially for live per-
formance. Since conventional modeling effects for line recording are not used
directly with a speaker, they do not include a power amp circuit, output trans-
former, or speaker. In other words, they only have a preamp circuit.
A real valve amp sound, however, is produced not just by the preamp, but also by
the tone and distortion of the power amp, and by the constant changes in
impedance that are created by the power amp driving the speakers. The SV-1
contains an actual low-wattage valve power amp circuit, a virtual output trans-
former that uses solid-state components to simulate an output transformer, and
a dummy speaker circuit that simulates the varying impedance of a real speaker.
This means that although it's low-power, the SV-1 has the same circuit structure
of an actual all-valve amp.
This is great when playing live, because the sound arriving to the main mixer is
the same of a real analogue amp captured by high-quality mics.
