1.0 THE THREE AMPS IN THE TRIAMP® MK II

Three totally different amps in a single housing? Until the mid-‘90s, this was thought to be an impossible dream.

The Hughes & Kettner team was undeterred: Years of intense development efforts and research culminated in the TriAmp®, and this magical combination debuted in 1995. To make the dream reality, we developed an unprecedented switching technology that delivers totally indepen- dent fundamental sounds of the highest quality. Each of the three preamps is dual-channel

in design so a total of six sounds are available at the touch of a button.

How does TriAmp® MK II produce such funda- mentally different sounds with just one power amp and a common master section?

TriAmp's tonal potential lies primarily in its puristic tube design. Highly advanced new switching technology developed by Hughes & Kettner for this amp reconfigures the multiple tube stages with each new sound you select. This new design pulls every drop of tone out of the all-tube circuitry, lending TriAmp® MK II incredible tonal flexibility without any reliance on solid-state compromises. The power amp design further supports TriAmp® MK II's vast range of tones:

In each channel, the Presence attenuation factor is switched automatically via a special capacitor. This lends each channel its trademark power amp characteristics and explains why they are so easily adjusted using just one Presence knob in the MASTER section.
