AUDIO-GD NOS 11 - MASTER

DAC Symmetry / Headphone Preamplifier / Amplifier

Audio-GD MASTER-11

Power and versatility side by side ...

Audio-GD presents us this time a symmetrical DAC ultra efficient all in one, associated with a preamplifier and amplifier headphone. The NOS 11 MASTER is a perfect fusion of the MASTER 7 and the MASTER 9. It is thus logically destined to become a cult DAC in the history of Mr. He Qinghua's firm.

Even if Audio-GD had already given their nobility to MASTER 7 and 9, the best engineers of the brand offer here a 3-in-1 DAC in its most accomplished form with outstanding performances.

Oversampling modes and a "NOS" mode

The great novelty concerning the MASTER 11 is the mode without Oversampling "NOS". DSP 1 includes two separate operations. This new DSP makes it possible to get rid of the noise problems associated with 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 mode allows processing on DSP FIFO with algorithm.

An interior and connectivity particularly provided

This NOS 11 is designed around 4 PCM1704UK converters and an Altera Cyclone DSP that work in parallel, as well as a Class-A ACSS discrete circuit without any PDO with separate power supply.
It has 6 digital inputs: BNC / RCA / Toslink / I2S optics via RJ45 / USB-B (AMANERO), as well as 3 analog inputs for preamplification: XLR and 2x RCA. The DAC and preamp outputs are in RCA and XLR, and the headphone output stage consists of an XLR 4 PIN, two XLR 3 PIN, and a 6.35mm jack output.
TheThe result is a great musicality thanks to an exceptional dynamic and an extremely rich rich sound.

A sophisticated and sharp architecture

PCM1704UK / I2S / USB AMANERO / TCXO / NOS

The NOS 11 is equipped with no less than 3 R-Core transformers (195W total), NOVER capacitors (50000uF in total), and famous Dale resistors. Separate controllers are responsible for developing one of the best signal-to-noise ratios for a DAC in this category.

A clock haa precision TCXO is present in this NOS 11 in order to significantly lower the Jitter. Each Audio-GD product is scrupulously tested in all seams with one of the most powerful systems in the world: the Audio Analyzers 2700 Series.

Amanero Isolated

As usual, Audio-GD integrates an excellent Amanero Combo 384 asynchronous USB chip into its product, supporting sampling rates up to 32bit 384kHz. In addition, Audio-GD upgrades its Amanero module by adding an isolator, making it possible to obtain a more transparent and accurate reproduction.

DSP Altera Cyclone 2

DSP - Altera Cyclone II

The French definition of DSP would call it "Digital Signal Process", or "Digital Signal Processing". This mini processor is optimized to process a large amount of data in parallel with each clock cycle. It is very efficient to process the digital signals that arrive to it. The Altera Cyclone in this Audio-GD NOS 11 makes it a very high fidelity product.

4x PCM1704UK

These four analog digital converters (DAC) use the R2R conversion which consists in directly using the bits of the digital signals to reconstruct the analog signals, all thisby acting on a network consisting solely of resistors having a given value (R) and its double (2R), without going through an over-sampling phase.
