TECHNICS SU-GX70 BLACK

SU-GX70 BLACK

Grand Class Series;
- Stereophonic integrated amplifier with Ethernet/Wi-Fi network streamer, Bluetooth, DAC converter for external digital sources including HDMI ARC interface, built-in DAB/DAB+/FM tuner and MM Phono stage;
- Innovative design resulting from a unique approach, a concentrate of highly advanced technology, meticulous design and construction with superior quality components, capable of surprising performance;
- Power output of 40 Watts per channel into 8 Ohms and 80 Watts per channel into 4 Ohms;
- Frequency response 20 Hz - 40 kHz (-3 dB, 4 Ohms) for line signals, 20 Hz - 80 kHz (-3 dB, 4 Ohms) for digital signals and 20 Hz - 20 kHz for Phono signals (RIAA deviation +/-1 dB, 4 Ohms);
- Compatible with load impedances between 4 and 16 Ohms;
- Extremely clean layout with rationalized separation of the different sections;
- Fully digital signal path from the input stage to the speaker output terminals;
- Discrete component input stage with low-noise FET and exclusive circuit with JENO (Jitter Elimination and Noise Shaping Optimization) processor, which performs high-precision Pulse Width Modulation (PMW) conversion using a clock generator in the noise-shaping system, capable of eliminating jitter across the entire frequency spectrum;
- Proprietary active technology Load Adaptive Phase Calibration (LAPC), capable of detecting the impulse returned by the speaker load and applying digital signal correction to perfect the amplifier's response system, whose power is delivered ideally with dynamic, detailed, very low-distortion transmission free from phase anomalies, with excellent driving capabilities for any speaker, regardless of impedance variations and across the entire frequency spectrum;
- Encapsulated and shielded high-quality MM Phono preamplifier stage;
- Twin Power Supply switching power supply stage with a fixed frequency of 130 kHz, highly reactive and efficient, with separate power supplies for the amplification stage and other circuits;
- Proprietary Space Tune technology to finely adjust acoustic emission characteristics to adapt them to the specific listening environment, equipped with effective and very useful presets for the most common positioning types and customizable in Custom mode (currently only on iOS devices) to obtain an extremely accurate and tailored response for your room;
- Pure Amplification mode, activatable at your discretion, capable of reproducing sound with maximum purity thanks to the ability to individually deactivate the power supply of the network and HDMI circuits;
- HDMI ARC interface uniquely designed to obtain crystal clear and jitter-free audio, with a direct signal path from the TV to the JENO circuit;
- Playback of digital sources with conversion of native DSD formats in ASIO and DoP up to 11.2 MHz and PCM up to 32 bit / 384 kHz;
- Roon Ready certification and streaming technologies Spotify Connect, TIDAL Connect (with native MQA decoding), Amazon Music, Internet Radio, Apple AirPlay 2, Google Cast with Multiroom functionality;
- Possibility of interfacing with a NAS or any network server installed on a device in the local network with support for DSD audio formats up to 11.2 MHz and PCM up to 32/384 (WAV, FLAC, AIFF, ALAC, AAC, MP3);
- USB Type-A port on the front panel for playing DSD audio files up to 11.2 MHz and PCM up to 32/384 (WAV, FLAC, AIFF, ALAC, AAC, MP3) from mass storage devices with a maximum capacity of 2 TB, formatted with NTFS, FAT32 or FAT file system;
