Product Code: SC-C70
The amp section of the OTTAVA™ f succeeds the Technics Reference System design concept and embraces a fully-digital amp configuration equipped with JENO Engine (Jitter Elimination and Noise-shaping Optimization) in order to deliver all of the audio data contained in the high-resolution sound source faithfully to the speakers without loss. Moreover, the OTTAVA™ f is equipped with three units of the same JENO Engine as those used in our high-end models to optimally drive the built-in speakers, thus achieving a high-quality, integrated hi-fi system that meets Technics standards. It adopts a bi-amp structure to separately drive the woofers (low-frequency sound) and tweeter/mid-range speaker units (mid-/high-frequency sound), and utilises the high-performance signal processing circuitry (DSP) mounted in the JENO engine to achieve precise channel dividing, adjustment of time alignment between speaker units, and correction of frequency characteristics.
The LAPC technology is applied even to the control of sound characteristics to realise "Space Tune™" for correcting changes in frequency characteristics that occur in actual use due to installation conditions.
LAPC is an original Technics speaker load adaptive technology. It measures the amp's frequency amplitude phase characteristics with speakers connected to the unit, and performs digital signal processing to achieve the ideal impulse response. Characteristic parameters optimised for the low-frequency and high-frequency speaker load characteristics of speakers are already pre-set in the LAPC computation circuit of the unit to realise ideal frequency and phase characteristics over the entire frequency range.
Regular power supplies use one transformer to supply power to the amp, CD drive, and digital circuits, and so if there is any load fluctuation or if noise occurs on a circuit, other circuits are affected, which results in degradation of the sound quality. This power supply system includes independently installed switch mode power supply circuitry for the amp and the other circuits, which eliminates mutual interference, thereby reducing degradation of sound quality caused by noise or power supply fluctuations. In addition, a layout with dedicated transformer and amp circuits enables the shortest possible connection to further reduce noise.
Space Tune™ delivers optimised sound for the customer’s listening environment.
