The Hughes & Kettner TriAmp Mark 3 is a 145W tube amplifier head designed to provide versatile tones, multiple tube configurations, and MIDI programmability for guitarists in rehearsals, recording sessions, and live performances. It features fifteen tubes, six channels, and three power amps capable of driving 4, 8, or 16 Ohms speaker cabinets via four 1/4" speaker outputs. By choosing different combinations of power tubes via three dedicated switches, the output power can be set to 72, 84, 126, 132, or 145 watts. Utilize the front-panel buttons or the supplied 7-button MIDI board to select channels, boost, and more.
Each of the six channels offers treble, mid, bass, gain, and master controls, while the master section includes volume, presence, and resonance parameters. Use the adjustable noise gate to minimize hiss and hum when you're not playing. Integrate stompboxes via the selectable 1/4" effects loop, which can be run in series or parallel. An XLR 3-pin jack delivers a balanced DI output for direct connection to a mixing console or audio interface. Red Box AE (ambience emulation) brings configurable cabinet emulation with choices including low cut and two cabinet modes.
Integrated TSC (Tube Safety Control) keeps the tubes biased properly and shows tube status via rear-panel LEDs. You can even swap the factory-installed tubes for different models; TSC automatically adjusts the bias. For increased protection during transport and storage, the TriAmp Mark 3 is supplied with a protective cover.
