    Product Description

    Premium Class C700 Series System:

    System consists of Stereo Integrated Amplifier SU-C700, Network Audio Player ST-C700, Compact Disc Player SL-C700 and Speakers SB-C700.

    SU-C700:
    JENO Engine
     (Jitter Elimination and Noise-shaping Optimization)

    Just like the R1, the SU-C700 is a fully-digital amplifier and delivers high-resolution digital signals without any distortion being introduced between the input stage and output to the speakers. Technics has developed an original jitter-reduction circuit, avoiding the sound quality degradation due to jitter common to conventional digital amps. It uses a clock generator for the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter to suppress jitter in the high-frequency range.

LAPC (Load Adaptive Phase Calibration)

Technics has developed a speaker impedance optimisation algorithm, using digital signal processing to flatten both the amplitude and phase-frequency response to make the most of your speakers. The result is a sound with better focus, spaciousness and definition.

High-speed Silent Linear Power Supply

Using a large-current Schottky-barrier diode, a rectifier circuit with electrolytic capacitors, and a stabilised power supply circuit, the SU-C700 ensures ample power supply at all times, even when dynamic music demands high current.

Battery Driven Clock Generator

Technics used battery power for low-noise applications in analogue amplifiers in the past: here, this same technology is used to improve digital clock precision, enhancing the definition of the sound.

Various Inputs

The SU-C700 supports a wide range of inputs, such as SPDIF, Analogue and Phono, as well as USB-DAC for connection of a PC. The digital input terminal supports coaxial 192-kHz/24-bit PCM and optical 96-kHz/24-bit. The USB DAC input terminal supports 192-kHz 32-bit PCM and 2.8-MHz/5.6-MHz DSD native playback (analogue output) and asynchronous transmission. The SU-C700 converts analogue signals to high-precision 192-kHz/24-bit PCM signals using the A/D converter. The full-digital system achieves high-purity reproduction from any content.

Speakers:

Point Sound Source Speaker System

Technics’ newly developed flat coaxial two-way speaker unit combines a tweeter for high frequencies and a woofer for mid-range and bass. Because the tweeter is at the centre of the woofer, the speaker acts as a point sound source, providing a coherent, integrated sound across the frequency range, without directional anomalies. As a result, the Technics Speaker System deliver a live superb soundstage focus, excellent imaging and the ambience required to deliver the ‘live music’ experience.

Phase Precision Driver (Flat Coaxial 2-Way Speaker Unit)

The flat coaxial two-way speaker drive unit is an original Technics development, designed for the faithful reproduction of mid-range and high-frequency sound. The flat woofer diaphragm has a sandwich-structure using lightweight, high-rigidity carbon fibre skins and a honeycomb core, and is designed for a highly accurate pistonic motion over a frequency range extending beyond the crossover frequency with the tweeter, thus ensuring smooth integration.
The flat design eliminates the frequency anomalies due to the cavity effect caused by conventional cone diaphragms, while the magnetic circuit employs a large magnet, copper cap and shorting ring, and a short voice coil with concentrated edgewise winding for high power with low distortion. The drive unit chassis is in highly rigid die-cast aluminium, with the chassis ‘legs’ having a resonance dispersing structure to eliminate even the smallest unwanted vibration, to help the drive unit deliver accurate and powerful bass.

High Rigidity Entasis Form Cabinet

The SB-C700 cabinet is designed to support the Point Source drive units securely, preventing unwanted resonance and ensuring a smooth flow of sound without diffraction or reflection. The front baffle is designed for maximum stiffness and resonance-damping, while the side panels are convex high-rigidity boards with a maximum 42-mm thickness, designed to damp down resonance while also preventing internal reflections.
The monocoque cabinet offers high rigidity, as each side of the cubic structure reinforces the adjacent panels. This reduces unwanted resonance by controlling the movement of the individual panels, as well as that of the structure as a whole, while internal acoustic absorbent material was selected, and its position optimised, to suit both a drive unit and the cabinet volume, thus suppressing undesired standing waves.
The bass reflex port on the rear panel is of a ‘parabola’ design, its curvature continuously varying from the inlet to the outlet to suppress turbulence at the exit as well flow-noise within the port, thus delivering smooth and powerful bass sound with minimum noise.
The glossy cabinet is created by repeated coating, sanding, polishing and finishing with a high degree of craftsmanship. This creates a cabinet not just attractive to look at, but also able to suppress fine vibrations generated at the enclosure surface, thus contributing to the accuracy of its sound.

High Quality Network Circuit

The High-quality Network Circuit was created as a result of extensive designing and listening, in order to maximise the performance of each speaker unit and achieve a balanced sound. To prevent interference between the drive units and minimise the effect of vibration, separate network boards for woofer and tweeter are optimally arranged inside the cabinet.

Ultra Wide Range Reproduction

The Technics Speaker System is capable of reproducing sound over the ultra-wide frequency range of up to 100 kHz to deliver the vast frequency spectrum offered by high-quality, high-resolution music sources. The result is a faithful reproduction of audio signals with all nuances intact.
