The technology behind the Black Spirit 200’s core
Unlike a full digital modelling amplifier, Hughes & Kettner says the Black Spirit’s core sounds come from analogue solid-state circuits under digital control. It’s ironic that even the simplest valve circuits can take many lines of code and thousands of transistors to recreate in the digital domain; high voltage means there are all kinds of complex interactions going on in between components, as well as the obvious ones that exist between output valves, transformers and loudspeakers. It’s easy to make some varieties of transistors behave like valves, but controlling them dynamically so they can mimic things like power amp sagging isn’t. H&K is keeping it to itself, but we have an inkling that this may be what’s going on inside the Spirit Tone Generator.
