Newly developed "ADCT", power supply with both fast response and low noise.
New "Intelligent PHONO EQ" and other technologies that revolutionize pre-amplifiers
High-precision signal processing amplifies audio while maintaining a high level of purity, and transmits it to speakers. To achieve this, Technics has developed a full digital amplifier technology centered on the JENO Engine. ADCT (Active Distortion Cancelling Technology)," which achieves a high drive capability for the speakers and realizes a magnificent, energetic playback sound, and the adoption of a power supply that achieves both high-speed switching and low noise for high responsiveness that instantly follows the music signal. The adoption of a power supply, for example, has dramatically improved the perfection of the digital amplifier. In addition, in order to fully support analog sources as well as digital sources, the discrete-design analog input section and the "Intelligent PHONO EQ," which incorporates a high-precision A/D conversion circuit and digital processing for PHONO input to enhance precision, have been adopted. In addition, the PHONO input uses an intelligent PHONO EQ that incorporates a high-precision A/D conversion circuit and digital processing to enhance precision, in pursuit of high-quality sound reproduction for all music sources. The SU-R1000 is the result of uncompromising development for high sound quality, including circuit design and chassis design that separates the preamplifier and power amplifier sections into separate layers and ensures the separation and independence of each block. The SU-R1000 is the result of the integration of Technics' technologies with the aim of becoming the reference amplifier of the future.

The evolution of Technics' full-digital amplifiers
The "JENO Engine" achieves low-noise, high-purity, dynamic sound through full digital processing.
Full-digital amplifiers have the advantage of being free from noise and distortion, but the jitter inherent in digital processing has a negative impact on sound quality. The JENO Engine is equipped with a unique jitter reduction circuit to solve the sound quality degradation caused by jitter. This circuit consists of a noise-shaping clock regeneration circuit that suppresses jitter in the low-frequency range and a high-precision sampling rate converter that suppresses jitter in the high-frequency range, ideally reducing jitter in the entire audible range. Combining this with our original high-precision PWM conversion circuit, we have achieved an outstanding expressive power that reproduces not only the high-resolution sound of digital sources, but also the soft feel of analog sources.
ADCT (Active Distortion Cancelling Circuit) to suppress distortion and convey the dynamism and energy of music
ADCT (Active Distortion Cancelling Technology) is a newly developed technology that precisely eliminates distortions generated in the power amplifier section due to causes such as instantaneous drops in supply voltage and back electromotive force when speakers are driven. Unlike the negative feedback circuit (NFB) used in analog amplifiers, which feeds back the music signal itself, this technology precisely extracts only the distortion components in the digital domain and cancels only the distortion, thus improving speaker drivability without compromising the transient characteristics that affect sound quality. This improves speaker drivability without compromising transient characteristics that affect sound quality, thereby reproducing the dynamism and energy of music signals as they are.
LAPC (Load Adaptive Phase Calibration)" for ideal impulse response
The impedance of a speaker varies with frequency. It is necessary to drive the speaker without being affected by its characteristics. However, in general digital amplifiers, the speaker is connected through a low-pass filter in the output stage, so the amplifier is more strongly affected by the impedance characteristics of the speaker. In addition, general amplifiers use negative feedback to improve the amplitude characteristics, but they cannot improve the phase characteristics. To solve this problem, we developed a speaker load adaptation algorithm that measures the frequency-amplitude and phase characteristics of the amplifier with a speaker connected, and corrects them to an ideal impulse response through digital signal processing. This enables the flattening of the amplitude and phase frequency characteristics, which was not possible with conventional amplifiers, and realizes the reproduction of sound with excellent spatial expression.
High-density mounting of the JENO Engine minimizes the signal path.
FPGA (Field Programmable Gate Array)
The JENO Engine of the SU-R1000 is mounted in a high-density FPGA to minimize the signal path inside the FPGA and to reduce the operating noise generated by the digital circuit. The FPGA is strictly enclosed in a copper shielded case to block out even the slightest noise. The FPGA is placed near the power amplifier to shorten the signal path. In addition to realizing a straight signal path, the left and right power amplifier sections, including the power supply circuit, are symmetrically laid out with the JENO Engine at the center, reducing mutual interference and enabling the reproduction of a rich sound field with excellent channel separation.

GaN-FET Driver" for output stage configuration with excellent linearity and drivability
High-speed, low-loss switching is essential for faithfully amplifying power from accurately generated PWM signals. To achieve this, a high-speed GaN-FET driver with extremely low internal loss is used as the switching element. Even a single push-pull configuration can be used to construct a high-power amplifier, thus minimizing the high-current signal path and enabling speaker drive with excellent linearity that can track both low and high volumes with high precision.

Thorough noise countermeasures improve clock accuracy and reduce jitter.
Battery Driven Clock Generator & Low Jitter
In order to increase the accuracy of the clock, which is the standard for operation in a full digital amplifier, the "Battery Driven Clock Generator" is used for the power supply of the clock circuit. By using a battery as the power source for the clock circuit, it eliminates the adverse effects of power supply noise on the clock circuit, and enables a high degree of clarity in sound image localization and spatial expression with good visibility. In addition, the clock itself uses a low phase noise type to ensure high precision.

Advanced Speed Silent Power Supply
While switching power supplies have excellent instantaneous power supply capability and can produce a powerful sound, they also have the harmful effect of generating noise due to switching operations. In order to further reduce this noise, we have developed a new, more advanced high-speed switching power supply. In the past, Technics focused on reducing this noise and fixed the switching frequency, but in the SU-R1000, the frequency has been increased from approximately 100 kHz to approximately 400 kHz, keeping the effect on the music playback band to an extremely low level. The SU-R1000 is also equipped with an ultra-low noise regulator in the rear stage to achieve low noise and stable power supply at a high level. A wide-band, low-noise reference voltage generation circuit and a control circuit that ensures stable gain achieve flat, ultra-low noise characteristics down to the low frequency range. Stable power supply output is realized.
High-speed GaN devices and SiC diodes for rectification
GaN-FETs, which are high-speed devices with extremely low internal loss, are used as switching devices for the power supply circuit. In addition, SiC diodes are used in the rectifier circuit, which have high withstand voltage and can significantly reduce recovery loss, and other high quality parts are used sparingly to construct a powerful power supply unit.

The preamplifier and power amplifier sections are separated into two stages.
Separated Power Supply": Separate and independent power supply sections for each circuit
In the SU-R1000, the preamplifier section, which handles fine input signals, and the power amplifier section, which handles amplified output signals, are separated into two floors. The preamplifier section in the lower stage has a structure that separates the analog signal processing block from the digital signal processing block, and each is supplied from a dedicated power supply. The power amplifier section in the upper stage has a symmetrical independent structure with separate power supply circuits for the left and right sides. By making the power supplies of each block with different functions independent, unnecessary interference between the blocks is prevented, and high S/N and high separation are achieved.

In addition, the PHONO input and analog input sections are fully discrete, and an ideal symmetrical layout has been achieved, and every detail has been thoroughly tuned. This suppresses interference between the left and right channels and improves channel separation. In addition, the XLR input section of the PHONO input section is fully balanced to reduce the influence of noise and provide a fresh signal transmission.

Digital Noise Isolation Architecture
The SU-R1000 supports the input of a wide variety of digital music content. However, many storage media, such as NAS and PCs, do not have sufficient low noise performance required for pure audio. Therefore, each interface line is isolated and equipped with a jitter remover to prevent jitter. The digital input section is equipped with capacitors made of high quality ruby mica and a power conditioner using non-magnetic carbon film resistors to block electrical noise from PCs and other connected devices and reduce the influence of external noise.

By shutting down unnecessary circuits, the noise generated within the device during music playback is minimized and the purity of the sound is enhanced.
High Rigidity Metal Double Chassis
High Rigidity Metal Double Chassis
In order to eliminate vibrations from the chassis, which are a source of noise, the chassis has been made highly rigid. The inner chassis has a two-stage separate structure with the upper floor for the power amplifier section consisting of the amplification circuit and its power supply circuit, and the lower floor for the preamplifier section consisting of the analog input section including the phono equalizer section, the digital input section, and its power supply circuit. The upper and lower sections and each circuit block are divided by a steel plate shield. The upper and lower sections, as well as each circuit block, are divided by steel plate shielding, which also functions as a reinforcing material to strengthen the rigidity of the entire chassis. The exterior front panel is made of 10mm thick, and the side and top panels are made of 6mm thick anodized aluminum to improve rigidity and vibration control. In addition, the insulator supporting the chassis is made of cast iron, which is highly rigid and has excellent signal damping characteristics. These features reduce internal vibration and eliminate external vibrations at a high level.
A traditional large double-needle meter is used.

A hybrid configuration of analog and digital circuits.
Accurate EQ Curve" for accurate EQ curves
The SU-R1000 takes advantage of the unique characteristics of a fully digital amplifier to combine digital signal processing with the newly developed "Intelligent PHONO EQ" to achieve higher sound quality than can be achieved with analog circuits alone. It consists of three technologies: Accurate EQ Curve, Crosstalk Canceller, and PHONO Response Optimiser, and is compatible with MM and MC inputs. Full-discrete circuitry with balanced transmission in all stages reproduces the minute signals of MC cartridges without being buried by noise. The Accurate EQ Curve, which processes the phono equalizer, uses a hybrid configuration of analog and digital circuits for the equalizer. The analog circuitry amplifies the minute signals from the record, suppresses conversion errors during A/D conversion, and the digital filter creates an accurate equalizer curve with no left/right levels or variations, resulting in a highly accurate phono equalizer. In addition, it supports 7 types** of various correction curves, including RIAA curve. This allows for more faithful reproduction of the vast and diverse sound of analog records.
All EQ curves except RIAA are simulated by us based on various references.

Crosstalk Canceller" measures and improves cartridge-specific crosstalk characteristics
Since a cartridge uses a single needle to pick up the stereo signals engraved in the grooves of a record, the occurrence of left-right crosstalk is inevitable and affects the sound quality. The "Crosstalk Canceller" uses the included "Calibration Record" to measure your cartridge*** and improves its characteristics by cancelling the crosstalk using DSP, thus reproducing the original sound of the record groove more faithfully. **** In addition, the following "PHONO Response Optimiser" also measures and corrects at the same time. You can save three cartridge correction data in the built-in memory and enter their names, and switch between them according to the cartridge.
If you are using a mono cartridge, please do not use this function. This function is only for stereo cartridges. This function is designed for stereo cartridges only.
This function is designed for stereo cartridges only. ＊＊＊＊ The effect has been verified using the "Calibration Record" included in the package. Please note that the sound quality effect may vary depending on the type and condition of your player, cartridge, and record, as well as other operating environments.
PHONO Response Optimiser" for correcting disturbances in cartridge frequency response
In addition to measuring and correcting crosstalk characteristics, the PHONO Response Optimiser uses DSP to correct for the effects of impedance matching between the cartridge and phono equalizer. In addition to measuring and correcting crosstalk characteristics, the PHONO Response Optimiser uses DSP to correct the effects of impedance matching between the cartridge and phono equalizer. The addition of a switch for impedance matching eliminates the possibility of noise contamination, enabling playback that brings out the true sound of the cartridge.
PHONO XLR" reduces the influence of noise and realizes highly pure signal transmission.
USB-B" for improved usability with support for two connections
In addition to the standard pin jack terminal, the PHONO input terminal is also compatible with the PHONO XLR input (MC only) used in high-end phono equalizers. This greatly reduces the effect of noise in signal transmission from MC cartridges with low output voltage, and enables highly pure signal transmission.
In addition, two USB-B ports are provided for constant connection to a network audio server, and for connection to a notebook PC for improved usability.
