Luxman T-12


The Luxman T-12 is an exclusive FM tuner of Accutouch Quartz Lock system. The most eminent feature of this Accutouch system is to seize the exact tuning points even including that at the RF stage even if such ambient condition as temperature fluctuates.

In conventional quartz lock system this operates only to keep stable the local oscillator, and provides no effect to the RF stage. Therefore, tuning accuracy depends on the actual tuning operation, which may cause deterioration of such characteristics as distortion, IF response ratio or separation etc. While, with the T-12, an accurate center point is detected by use of quartz circuit and the exact point is mechanically locked, thus possible tuning error is completely removed.

Naturally, the primary target of the T-12 is placed at the sonic excellence. At the front end, a five-gang tuning capacitor exclusively made for FM is adopted to utilize every superb characteristic obtained at the IF and its following stage. High selectivity at each RF amp ensures sufficient inter-
ference rejection performance.

IF bandwidth selector is provided, which realizes ultra low distortion characteristic in the wide position thanks to two pairs of LC block filter of good phase characteristic, and in the narrow position, high selectivity is obtained by coupling a ceramic filter with a block filter. Also the quadrature wideband detecting circuit contribute to lower the distortion.

The multiplex circuit with pilot canceller, improvement of the phase characteristic of the low-pass filter, and adoption of DC-amp configuration at the audio output stage, all of these help realize superb sonic quality.

The T-12 represents the finest standards of design and craftsmanship, but the proof is in your handling and listening.
