Top class, quality sound

The SL-G700 Super Audio CD Network Player is a feature-packed digital player that delivers the highest quality audio from most of today's audio transmission and storage media, from traditional CD/SACD to today's high-resolution audio media and streaming services.

High quality premium D/A converter based on dual mono circuit

The circuit of the digital-to-analog converter is the most important element of the device that outputs an analog audio signal: it is in this circuit that the digital signal read from the carrier (for example, from a CD) is converted to analog with the original waveform. High-quality DAC AK4497 devices from Asahi Kasei Microdevices were chosen as converters for the right and left channels, which are distinguished by a high level of signal to noise and low distortion. The power supply is supplied separately to each converter and is divided into five sections depending on the purpose. To ensure the accuracy of signal conversion, the clock generator is connected to a separate battery power circuit. The use of two asymmetrical mono circuits avoids mutual interference between the left and right channels, raising the bar for reproducing recorded sound and sound space to a new level.

External amplification module

The filter circuit, located behind the D/A converter, determines the quality of the audio coming to the analog output. Instead of an IC op amp, the SL-G700's filter circuit contains a special amplifying module of an original design. The use of low noise transistors and thin film resistors suppresses noise generated in the circuit. Fine-tuning operating parameters such as operating current improves response, signal-to-noise ratio, and distortion. All this ensures high linearity and fidelity of sound reproduction by the SL-G700 device, including the smallest nuances of the recording.

High speed quiet hybrid power supply

To reproduce sound with high fidelity, the quality of the power supply is of particular importance. Noise in the power supply and the stability of the power supply directly affect the sound quality reproduced from audio signals, especially for analog channels. The SL-G700 has a dedicated open-loop analog audio output power supply capable of suppressing modulation frequency fluctuations. Combined with an ingeniously designed stabilized power supply, this dedicated power supply delivers stable, low-noise power. This dedicated circuit does not use general purpose ICs; in addition, the parameters of this circuit have been carefully tuned to provide the high signal-to-noise ratio and therefore the faithful sound reproduction that Technics products are known for.

High quality headphone output

Typically, the analog output signal (balanced or not) and the headphone output signal come from the same digital-to-analog converter circuit. At the same time, the SL-G700 has a separate headphone transducer circuit that uses Technics' proprietary audio signal processing LSIs, JENO Engine digital amplifiers to eliminate distortion and optimize noise shaping. Separating the analog output and headphone circuits eliminates interference between the two circuits for different purposes. In addition, in each circuit, the sound is adjusted in the most appropriate way, which improves the signal quality at both outputs. The SL-G700 is also equipped with a performance optimization system that automatically starts the JENO amplifier when headphones are connected. This eliminates the undesirable influence of the analog output signal on the sound quality when headphones are not connected.

In addition, the Class AA headphone amplifier uses separate circuits to amplify the audio signal: the first increases the voltage, the second - the supply current. This allows the high-resolution PWM output from the JENO output to be converted to an analog signal with high accuracy, ideal for a wide range of headphone load impedance. Such a signal is characterized by low distortion over a wide frequency range.
