The K-05 and K-04 are the cassette decks developed under the ultimate yet essential proposition to realize ultimate fidelity reproduction of original sound. Most of the decks said to sound good accompany a certain colouration, and in many cases such particular atmosphere delivered by colouration is preferred in actual listening. Dissatisfaction at such present status urged LUXMAN to design the top-notch deks K-05 and K-04. Tape travel mechanism is life of tape deck and determines whole sound quality. Good tape transport is a precondition for a good deck. With the K-05 and K-04, the tape trasnport mechanism has been reviewed from the very begining not by means of such temporizing measure to provide ostensible reduction of wow & flutter with Direct Drive motor but by means of newly designed robust "G.T. Transport" - Grand Trust Mechanism, which eventually brought about a dramatic improvement of total tape travel mechanism. Rustic, sturdy chassis made of thick die-cast zinc alloy is moulded and integrated with 2 pairs of capstan bearings, which assures perfect parallelism between the shafts of pinch-roller and capstan as well as their strict verticality to the chassis. 3-DD Motor Configuration, exclusive motor is arranged for each function of capstan drive, reel drive and head-assembly movement.
High quality recording and playback are made possible only by an accurate 3-dimensional control on tape contact. Many manufacturers put great emphasis on the zimuth adjustment (to parallel both the head gaps for recording and playback and to set them perpendicular to tape) With the K-05 and K-04, all of these conditions are fully satisfied on the basis of ultra-precison R/P combination head. In the case of discrete 3-head system, the most critical point is in the azimuth control for the recording and playback heads. On the contrary, the R/P combination head has a big advantage that it can be fixed at the exact position in addition to its close positioning between the recording and playback head-gaps. To make the most of this merit, during the manufacturing process of the head, its azimuth is aligned in the strictest manner by the unit of microns. As commonly known, cassette tape has quality variations even in the same kind supplied under the same brand. To make most of its recording potential, an optimum value has to be selected for each bias current, tape-referenced recording level and equalization. In the case of the K-05 featuring automatic calibration system, the on-deck computer calibrates all of these 3 items individually then correlatively to locate the optimum points, confirming the result of each calibration step in the form of frequency response.
