More info

es9018k2m audiophonicsThis new CADAUDIOPHONICS I-SABRE ES9018K2Mallows you to access the High Resolution 32bit 384KHZ directly compatible on Rapsberry Pi.

TheDAC I-SABRE ES9018K2Mincludes a power input directly to 5V micro USB input. This input has an isolator (voltage isolation 3000VDC).

Special attention is given to the power supply with two controllers followed by capacitors ensuring the necessary stability for the DAC ESS SABER 32bit.

Like all DAC dedicated Raspberry PI on GPIO support, The AUDIOPHONICS I-SABRE ES9018K2Mincludes a large number of options. It thus allows to adapt to all the possibilities and project DIY HIFI.

Advanced analog outputs on 3 AOP NJM 2114D:

JRC 2114 ES9018K2MThis DAC includes a voltage stage with two AOP NJM 2114D corresponding to the technical drawings of ESS. A final AOP NJM2114 buffer finalizes the output stage.

A fully programmed microcontroller:

es9018k2m audiophonicsThis DAC includes an integrated controller programmed by our development team. Depending on the firmware used, you can control the 32 bit digital volume of the ESS SABER DAC.

Ce 32-bit volume with 64bit accumulator is the most powerful on the market. It also allows the volume management of the ES9018K2m in hardware via a kit button soon available.

An optional high-quality display:

es9018k2m audiophonics This optional screen of the most readable indicates the bit-rate, volume and various information from the DAC. It will suffice to connect it on 4 wires on the card of the DAC. it is managed by the microcontroller on the card.

It shows the main sampling frequencies, the I2S input and the volume level at the Décibel pré. Several sizes of screens will be available depending on the project or the desired assembly.


Outdoor power supply:

es9018k2m audiophonics OLEDThis DAC has an input on the circuit making it possible to input a voltage of 5V DC regulated directly on the ESS SABER ES9018K2M without going through the internal regulation. It is thus possible to further increase the decoding accuracy by any quality linear power supply. This DAC ES9018 K2M also allows the supply of Pi 3 or Pi 2 via the GPIO connector avoiding multiple unnecessary connections simplifying the arrangement of a case.

This DAC IS COMPATIBLE with REclocker 44 / 48MHZ ALLO KALI

Aucun son à 16/44 bits
Ik gebruik de laatse versie van Volumio, maar geen sabre driver en geen geluid bij 16/44 bit
Message from Audiophonics service
Vous utilisez certainement un système sur base MPD posant des soucis de décodage 16bit.
Favorisez une solution comme Picoreplayer fonctionnant parfaitement avec ce DAC.
