Press release

Achieves powerful speaker drive and dynamic low-frequency reproduction

Panasonic Corporation will release the SU-G700M2 stereo integrated amplifier with full digital configuration as a technics brand grand class integrated amplifier from November 26th.

This product inherits the high-resolution and information-rich musical expression of the conventional model SU-G700, and is a high-speed response and low-noise power supply "Advanced Speed ​​Silent Power" developed with the SU-R1000, which is the reference class of the highest class. "Supply" is adopted, and powerful speaker drive and dynamic low-pass reproduction are realized. In addition, while inheriting the structure in which the inside of the chassis is divided into three and the high-rigidity chassis with the bottom chassis as two layers of steel plates, the parts that contribute to improving sound quality have been thoroughly reviewed and adopted in various places, resulting in higher purity and higher resolution. Achieves improved sound. With these, you can enjoy clear and energetic music playback. Furthermore, the PHONO input is compatible with MC type cartridges in addition to MM type cartridges, and is compatible with various sources and peripheral devices from analog sound sources to digital sound sources. Silver and black are added to the lineup, and you can choose the color that matches your audio equipment.

We will propose this product to audio users who pursue discerning sound as a full-scale integrated amplifier that inherits the high-quality sound technology of high-end models.

This product is an integrated amplifier with the latest full digital configuration of Technics, which inherits the technology developed in the reference class SU-R1000. In order to further draw out the potential of the full digital amplifier "JENO Engine", the high-speed response and low-noise power supply "Advanced Speed ​​Silent Power Supply" developed with the SU-R1000 is adopted, and a high-speed operation device similar to the power supply section of the SU-R1000 is adopted. GaN-FET and SiC diodes are used to improve the responsiveness of high-speed switching power supplies. In addition, a wide variety of speakers can be driven with ideal amplitude and phase characteristics by using the load matching algorithm "LAPC" that optimizes the characteristics of the amplifier according to the characteristics of the speakers.

Inheriting the technology obtained in the development of SU-R1000, we adopted the power supply "Advanced Speed ​​Silent Power Supply" that combines a high-speed switching power supply and a low noise regulator. Similar to the SU-R1000, the switching frequency has been increased from the conventional 100 kHz to approximately 400 kHz, reducing the generation of ripple noise and noise interference in the audio band. The high-speed response instantly supplies stable energy to the power amplifier section and enhances the drive capability. In addition, by using a low noise regulator circuit and thoroughly reducing the noise of the power supply, high-purity music playback is realized.

Technics' original full digital amplifier "JENO Engine" and "LAPC (Load Adaptive Phase Calibration)" that optimizes the characteristics of the amplifier according to the characteristics of the speaker by measuring and analyzing the characteristics of the speaker, the resolution and It realizes music playback with excellent spatial expression.

Similar to the conventional model SU-G700, the power supply unit, power amplifier unit, and digital / analog input unit are divided into three parts. In addition, this product has a two-stage upper and lower power supply unit and is surrounded by a steel plate. It has a shield case structure. In addition, the steel plate that partitions each part uses a high-rigidity chassis with excellent vibration damping, which has a two-layer structure in which a 1.2 mm-thick steel plate bottom chassis is overlaid with a 2 mm-thick steel plate. These reduce the interference between each part, suppress unnecessary vibration, and eliminate the loss of detail due to the influence of noise.

In order to further improve the sound quality, we have selected high-quality sound parts by utilizing the know-how gained in the development of SU-R1000. The capacitors of the power supply section for the power amplifier have been changed to high-grade parts. In addition, the parts that contribute to sound quality improvement, such as using non-magnetic brass screws for the connection between the speaker terminal and the amplifier block and increasing the purity of the transmission signal to the speaker, have been thoroughly reviewed in various places. Adopted for.

"LC power filter" and "power conditioner" that realize high-purity sound reproduction by noise reduction, "Battery Driven Clock Generator" that reproduces clear sound image localization and clear space with thorough noise countermeasures, unnecessary circuits Equipped with various high-quality sound technologies such as the "Optimally Activated Circuit System" that stops and suppresses deterioration of sound quality, it can reproduce high-purity sound from analog sound sources to digital sound sources.

In addition to silver, a new black model will be released this time. This allows you to choose a color that matches other audio equipment you are using, such as players and speakers. In addition, the volume and input selector knobs made of solid aluminum are spin-processed not only on the front but also on the sides, and the exterior design inherits the SU-R1000 for a higher quality finish.
