The SU-GX70 Stereo 80-Watt Network Integrated Amplifier in black from Technics is a heavily featured streaming amplifier for your digital, analog, and wireless audio sources. With a discrete amp circuit redesigned and adapted from Technics Grand Class components, the SU-GX70 is designed for high-quality audio, no matter what you're listening to.
The SU-GX70 can play back high-resolution music wirelessly from the source stored in a smartphone, tablet or PC. It supports not only Bluetooth and AirPlay 2, but also Spotify Connect, Internet radio, and Chromecast built-in so that a wide range of music streaming services can be enjoyed. In addition to wireless streaming, you can connect to your network with the Ethernet LAN input, or connect a PC or flash drive directly via USB.
Technics thus developed a speaker impedance adaptive optimization 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 technique enables flattening of the frequency characteristics of amplitude and phase, which had previously not been achieved by amplifiers, while also delivering a sound with rich spatial expression.
As such, the video signals are output from the SU-GX70 at a lower rate, and the digital value of the color of each pixel is set to zero. This ensures low-load operation between the HDMI transmitting/receiving devices, preventing any unwanted noise generation from the video signals.
This also reduces any impact on sound quality. Further, transmitting the signals from the TV to the JENO Engine via the shortest possible route minimizes any further impact from jitter. This is a mechanism unique to Panasonic/Technics as HDMI licensors.
By using the Technics Audio Centre app for iOS devices or by selecting a setting from the four presets—Free, Wall, Corner and In a Shelf—using the main unit according to the installation location, the user can achieve the most suitable sound quality for a specific acoustic environment.
Furthermore, the L/R Custom feature lets the user enter the setting independently for the left and right speakers when the speakers are set up in different installation conditions. This brings out the best sound reproduction in any installation conditions.
