Audio GD NFB-27 DAC Vorverstärker mit Widerstandsnetzwerk Sabre ESS9018

Ausstellungsstück in technisch einwandfreiem Zustand in Originalverpackung! Optisch ebenfalls in sehr gutem Zustand (Siehe Fotos) Konfiguration: I2S Schnittstelle über RJ-45 auf Input 1 (siehe Foto von Rückseite), Ansonsten Standardkonfiguration Zubehör: Stromkabel, Originalfernbedienung, Originalverpackung Fully Discrete DAC+ Head amp / Preamplifier DSD , DXD support from USB 32bit / 384K Sabre ES9018 32bit / 384K Asynchronous Transfer USB-32 Chip 5 groups digital & 3 groups analogy inputs OCC wires and TCXOs built in Summarize Fully balanced design built by discrete analog stages without any OPA and couple caps in the signal channels. Non- feedback ACSS analog output stage . Uses three R-core transformers (135W total) separate power supplys for the digital part , right channel and left channel. More than 50,000uf audio grade NOVER capacitors are used to ensure ample and smooth power feed. A total of 11 class A PSU groups are used to purify the power supply. To achieve high S/N, the control circuit is powered with separate regulator. Uses most Hi-end grade parts and exact match transistors. Four-channel digitally controlled relay-based volume control to avoid channel imbalance and improve sound quality. NFB-27 has 99 steps volume level control in both high gain mode and low gain mode. 5 groups digital input : BNC / BNC+RCA coaxial / RCA coaxial / Optical / USB 3 groups analog preamp input : XLR / RCA / RCA Preamp / DAC output : XLR / RCA / ACSS (variable) Headphone output : 4 pins XLR / 6.3MM SE Memorizes all settings and resumes the last setting when powered on (see user manual). Belegung der I2S RJ-45 Schnittstelle: I2S-RJ45 input format: ( 3.3V level , we can''t guarantee the I2S input can cooperate with all I2S output devices. ( The I2S transmit want to take care the transmit cable ) Pin 1 : SDATA Pin 3 : LRCK Pin 5 : SCLK Pin 7 : NC Pin 2,4,6,8 GND Please note: Don''t hot push / pull of the I2S cable. Any time must power off the units then push or pull the I2S cable.
