High Precision Coherent D/A Converter
The SL-G700M2 is equipped with the High Precision Coherent D/A Converter, which is the result of the accumulation of these technologies, converts digital values to analog signals with the utmost precision and outputs them to an amplifier. It is composed of coherent processing, a high-performance D/A converter in dual monaural configuration, and a proprietary discrete amplifier circuit.
The dual ESS ES9026PRO is newly adopted for the DAC chip. The symmetrical placement of one L/R unit on each side and their independent transmission structures reduce mutual interference and faithfully reproduce the sound image and musical space contained in the sound source. The filter circuit after the D/A conversion uses an amplifier circuit with a unique discrete configuration instead of an operational amplifier IC. This realizes even higher responsiveness and S/N and reproduces even the most subtle sounds.
Coherent Processing Technology
Technics' new proprietary coherent processing technology improves the reproducibility of impulse signals by minimizing amplitude and phase deviations that occur throughout the D/A conversion process for signals up to 192 kHz PCM using proprietary digital signal processing*. With this processing, purity of the sound is increased, and the sound image is clearer.
*DSD signals such as Super Audio CD are input directly to the DAC without performing this processing.
Multi-Stage Silent Power Supply
Digital audio players that handle small signals require thorough noise suppression because even the slightest noise can significantly affect sound quality. The Multi-Stage Silent Power Supply provides thorough noise suppression in three stages: (1) High-speed switching power supply, (2) low-noise regulator, and (3) current injection active noise canceling. The SL-G700M2 uses a high-speed switching power supply of approximately 300 kHz, which is also used for the analog circuits of the SU-R1000 reference-class integrated amplifier. By increasing the switching frequency, the interference of noise on the music playback bandwidth is reduced and a highly responsive power supply is achieved. The low-noise regulator also provides low noise at a high level and a stable power supply are realized with the fine-tuning of circuit patterns.
Current Injection Active Noise Canceling
This newly developed technology, current injection active noise canceling removes unwanted noise components by applying an inverse phase current to the detected noise. More effective current noise rejection can be achieved by using the push/pull method in combination with conventional noise rejection by drawing current.
Super Audio CD and MQA, and New USB-B Input is Supported
The SL-G700M2 supports playback of Super Audio CD, which is a high-quality audio disc format. For further sound quality enhancement, a "Pure Disc Playback" mode, is dedicated for Super Audio CD/CD playback. This model also supports MQA and is capable of full decoding playback of MQA files and MQA-CDs. Various other high-resolution formats are also supported, including WAV/AIFF, FLAC/ALAC, and DSD file playback.
In addition, the SL-G700M2 is equipped with a new USB-B port that allows constant connection to a network audio server or PC for playback of high-resolution sound sources from the connected device.
Supports a Wide Variety of Music Sources and High Connectivity
The SL-G700M2 supports Chromecast built-in, which enables a wide range of music streaming services from Google Chromecast-enabled apps, as well as AirPlay 2. Wi-Fi® and Bluetooth® wireless connections are also supported.
Housing and Chassis that Support High Sound Quality and High-quality Design
The SL-G700M2 is divided into four sections inside the chassis, with the power supply, digital interface, analog circuitry, and disk drive sections, each being independent of the other. This suppresses mutual interference between circuits and reduces sound quality degradation. The disc drive adopts a three-layer chassis configuration. Powerful vibration-damping and quiet construction, including a disc tray made of die-cast aluminum, ensures high-precision disc playback. The exterior features a hairline-finished 7 mm-thick aluminum front panel and 3 mm-thick aluminum side panels, as well as an engraved Technics logo for a high-grade design and finish.
