AUDIO-GD NOS-19
NOS / DAC / DSP / 24bit - 192kHz / USB AMANERO / HDMI (I2S)
Very High Fidelity ...
The NOS-19 adapts to your needs by offering you this time a version equipped with an HDMI (I2S) and a USB Amanero.
Of course, it still benefits from the upgrade of its DSP, its additional clock dedicated to the management of the asynchronous transfers and the management of the sampling rates up to 384kHz.
As usual, Audio-GD and its technicians offer you a top-of-the-range product offering outstanding performance. 
Mode without OverSampling "NOS"
The strength of this NOS-19 is its OverSampling mode "NOS". The DSP 1 thus includes two distinct operating modes. This new DSP makes it possible to get rid of the noise problems related to the NOS mode while keeping its advantages in terms of musical pleasure thanks to a non-destructive -6dB filter.
Mode 1 favors the speed of data transfer, the second allows processing on DSP FIFO with algorithm.
A particularly efficient connection
The integrated PCM1704UK converter allows you to manage sources up to 24Bit / 192kHz. The NOS-19 has 4 inputs: Coaxial S / PDIF, Optical Toslink, USB Amanero and HDMI (I2S), as well as 2 analog outputs: RCA and ACSS. Its SPDIF interface is extremely powerful in terms of data processing for better audio quality.
Great musicality and exceptional dynamics
24bit / 192kHz / USB AMANERO / HDMI (I2S) / TCXO / ACSS
Every product of the brand is scrupulously tested in all seams with one of the most powerful systems in the world: the Audio Analyzers 2700 Series from Audio Precision.
The NOS-19 is equipped with an R-Core transformer, WIMA capacitors, and Date resistors. It is designed around the PCM1704UK and the Altera Cyclone DSP that work in parallel, as well as a Class A ACSS discrete circuit without any PDO with separate power supply.
TCXO - 100MHz
Usually the Audio-GD devices are equipped with the standard 80MHz clock, except this Audio-GD NOS-19 includes the 100MHz TCXO Ultra Low Jitter option. This TCXO (Temperature Compensated X (Crystal) Oscillator) clock is more precise and significantly reduces the jitter.
PCM1704UK
This analog digital converter makes use of the R2R conversion which consists in directly using the bits of the digital signals to reconstruct the analog signals, all this acting on a network constituted solely of resistors having a given value (R) and its double (2R ), without going through an over-sampling phase.
