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.Full Digital Amplifier The SU-GX70 uses a fully digital amplifier that incorporates Technics' renowned digital audio technology. Its digital transmission system processes signals fully digitally in all stages from input to output. Compared to analogue transmission, this system is less susceptible to signal degradation caused by external noise, ensuring more precise signal transmission. Accurate signal processing not only delivers high-resolution digital audio but also maintains the soft texture inherent in analogue recordings.Abundant Input Options, Diverse Network Functions This full digital amplifier features a wide variety of inputs including, Optical, digital coax, and HDMI ARC to seamlessly integrate into a home theater system with a TV. Analog sources include built-in FM radio, an MM Phono input, and two stereo RCA inputs with Pure Amplification Mode.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.JENO Engine (Jitter Elimination and Noise-Shaping Optimization) A JENO Engine has been used in the HDMI ARC (Audio Return Channel). This helps to reduce any degradation in sound quality caused by jitter during the transmission of digital audio signals, ensuring unparalleled levels of clarity in TV audio.Ideal Impulse Response through LAPC Speaker impedance changes with each frequency, and a power amplifier is required to drive speakers without being affected by the speaker s characteristics. However, conventional digital amplifiers are connected to speakers through a low-pass filter at the output stage, so they are even more strongly affected by the speaker impedance characteristics. Also, although the amplitude characteristics of conventional amplifiers due to negative feedback were improved, the phase characteristics could not be enhanced.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.Twin Power Supply Circuit System The design of the power supply is extremely critical in audio systems containing amplifiers, digital circuits, and other such components. To eliminate any adverse effects on the amplifier, the SU-GX70 is equipped with a dedicated power supply for the power amplifier circuits that is independent from all other circuits. As such, the same electrolytic capacitors installed in high-end models have been used in the dedicated amplifier power supply and the power amplifier components.HDMI ARC (Audio Return Channel) For the SU-GX70 to receive audio signals through the HDMI ARC (Audio Return Channel), due to the specifications, video signals must first be output from the SU-GX70. However, the output of these signals can cause unwanted noise.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
