Technics SU-R1000 - Stereo Integrated Amplifier Manual

Features

High-Quality Audio Technologies Employed integrated amplifier

The JENO Engine transmits and processes audio signals in full digital and with minimal jitter from the input stage to the power stage. GaN-FET Driver for the linear speaker drive with highspeed lossless switching, and ADCT (Active Distortion Cancelling Technology) cancels the noise precisely are implemented to achieve the energetic dynamic sound with the superior drive function.
The low-noise and clear sound can be provided by the various technologies such as LAPC that conducts speaker load adaptive phase calibration for ideal gain and phase characteristics of any type of connected speakers.

Low-noise power supply with high responsive ability to the audio signal

"Advanced Speed Silent Power Supply" is embedded for high-speed lossless switching and noise reduction. The unique power supply function can supply the stable power with the lowest noise by the high speed switching feature for the better resolution of audio signal in full digital amplifier.
And this unit improves the potential of JENO Engine for the better playback.

The unique digital technology "Intelligent PHONO EQ"

improves the potential for playback of records.

"Accurate EQ Curve" which has a hybrid component for analog and digital circuits enables the equalizer process with high-precise and S/N. And this unit supports the various equalizer curve other than RIAA for accurate playback.

"Crosstalk Canceller" function which measures the crosstalk and optimizes it with DSP, and "PHONO Response Optimizer" function reduces the resonances on the cartridge are implemented to reproduce the audio signal from the record groove.
