ThrillseekerXTC is a contemporary exciter build around a parallel analog equalizer design.
It takes our hearing sensitivity into account especially regarding the perception of audio transients, masking effects and loudness. ThrillseekerXTC offers frequency boosting on three individual parallel bands with pre-selected frequency ranges for the low, mid and high frequency spectrum. The mid band also performs compression by an opto-electrical circuit. A dedicated output stage adds further idiosyncrasies typically found in transformer coupled tube stages.
Decoupling EQ from DRIVE/MOJO controls – the latter now controls a dedicated downstream output amplifier stage
Improved overall THD performance featuring effectively distortion-free compression for the mid-range as well as a silky top-end
Updated components, two new audio transformer circuits introduced, new inductor based (LC) filter network
