Delivering the Ultimate Emotive Musical Experience to All.
At Technics we understand that the listening experience is not purely about technology but the magical and emotional relationship between people and music. We want people to experience music as it was originally intended and enable them to feel the emotional impact that enthuses and delights them. Through delivering this experience we want to support the development and enjoyment of the world's many musical cultures. This is our philosophy. With a combination of our love of music and the vast high-end audio experience of the Technics team, we stand committed to building a brand that provides the ultimate emotive musical experience by music lovers, for music lovers.



A Music Experience Like No Other.
New encounters with sound
The audio landscape has undergone many changes over the years. From recording techniques and equipment to playback devices and types of media, the audio environment is constantly evolving and diversifying with listening convenience becoming a central need. The rise of the Internet, and in particular broadband speeds, has made it possible to send and receive huge amounts of data allowing music to be digitally obtained at lossless quality. It is now time to enter the era of digital networks, not only putting into place our decades of audio experience, but pushing the boundaries of sound reproduction and enabling new encounters with sound for music lovers.
Technics - A lifetime partner
Over 100 years of analogue audio history, sound quality has matured to a level where people are satisfied with their listening experience. However, the digital era has much more to offer. We will utilise our decades of experience striving for the best sound reproduction possible, through both technology and design, to bring to the market a product with superior audio quality. However, this is just one step in our ultimate goal of bringing the world’s highest-class audio experience to music lovers, who will not settle for anything less than the Technics listening experience.

When Technics was relaunched several years ago by their parent company Panasonic, the company launched three new range:

Premium Class

Grand Class

Reference Class


Premium Class is centered around All-In One Compact Music Systems, while traditional 2-channel HiFi is reserved for Grand Class and Reference products.

Dooleys-HiFi support both Premium and Grand Class products

The Grand Class SU-G700 Integrated Amplifier inherits Reference-class High-quality Audio Technology

Inheriting the reference-class audio technology concept, the JENO Engine transmits and processes audio signals in full digital and with minimal jitter from the input stage to the power stage. Speaker load adaptive phase calibration (LAPC) ensures ideal gain and phase characteristics for any type of speaker. The newly developed low-distortion switching power supply realises accurate power supply by suppressing switching frequency fluctuations caused by load shifting.

JENO Engine
(Jitter Elimination and Noise-shaping Optimization)
Concept of JENO Engine, Block Diagram of Digital Amplifier
In order to faithfully transmit the massive amount of audio data sent to the speakers without loss, the SU-G700 power amp section uses full digital amplification employing the JENO Engine, based on the design concept of reference systems. In order to solve the issue of sound quality degradation due to jitter, which poses problems for conventional digital amplifiers, the SU-G700 has an original jitter reduction circuit that eliminates jitter over the entire audible frequency range. Also, a unique, high-precision PWM (Pulse Width Modulation) conversion circuit is used for PWM conversion, which is important for sound quality. By optimising items such as the noise-shaping speed, degree, and quantization number through our unique expertise, data even in the wide dynamic range contained in high-resolution sound sources is converted to PWM signals without loss. These technologies provide reproduction of natural and finely detailed sound, enabling perception even of delicate music nuances.

LAPC
(Load Adaptive Phase Calibration)
Concept of LAPC, Gain and Delay by Conventional Amplifier / LAPC
Speaker impedance changes with each frequency and a power amplifier is required to drive speakers without being affected by the speaker’s characteristics. However, conventional digital amplifiers are connected to speakers through a low-pass filter at the output stage, so they are even more strongly affected by the speaker impedance characteristics. Also, although the amplitude characteristics of conventional amplifiers due to negative feedback were improved, the phase characteristics could not be enhanced. We thus developed a speaker impedance adaptive optimisation algorithm that performs correction to the ideal impulse response through digital signal processing by measuring the frequency amplitude-phase characteristics of the amplifier with the speakers connected. This new technique enables flattening the frequency characteristics of amplitude and phase, which had previously not been achieved by amplifiers, as well as delivering a sound with rich spatial expression.

High-speed Silent Hybrid Power Supply
Concept of High-speed Silent Hybrid Power Supply
With a conventional switch mode power supply, the switching frequency changes in response to the load fluctuation in order to control the switching ON time for stabilising the output voltage. This fluctuation component in the switching frequency has a negative impact on sound quality. The newly developed power supply reduces the noise component harmful to sound quality by fixing the switching frequency. In addition, the latter stage in the switching power supply is provided with a linear regulator to stabilise the output voltage. The linear regulator uses custom, high-definition electrolytic capacitors.
What's more, our current resonance-type power supply decreases the level of switching noise. The parts used for absorbing noise, such as capacitors, were carefully selected. All possible measures were taken to achieve low noise and reproduce clear sound.

Three-section Configuration

In integrated amplifiers there are a variety of circuits, including circuits that handle the micro-signals of inputs and those that handle a large current, such as output circuits and power-supply circuits. The SU-G700 uses a three-section construction with partitions installed between the circuit blocks according to the signal level handled. This eliminates interference between circuit blocks, thus achieving clear sound quality. Also, the chassis rigidity due to this construction suppresses the vibration of electrical parts, thereby suppressing deterioration in sound quality.

Low-noise PHONO Input

The PHONO input achieves low noise by using a differential parallel connection configuration of a first-stage, low-noise FET. In addition, four-level gain adjustment enables selection of the best gain according to the cartridge output. This enables optimal playback of high-grade analogue recorded sound sources tailored to the user's environment.

Class AA Headphone Amplifier

Concept of Class AA Headphone Amplifier, A:Voltage amplification is performed without any load current so the input signal is faithfully amplified. B: The necessary current is supplied to the load according to the output voltage of the voltage amplifier.
The SU-G700 uses a Class AA headphone amplifier with separate amplifier circuits for voltage amplification and current amplification of the audio signal. The voltage is amplified by a high-grade operational amplifier, the current is amplified by an operational amplifier with high current-supply capability, and the high-grade PWM signal output from the JENO Engine is converted to analogue with high precision, thus enabling headphones to be ideally driven. This makes it possible to reproduce music with low distortion and a wide frequency range no matter what the load impedance of the headphones is.
