Audiophonics I-Sabre V4

DAC ES9023 TCXO Raspberry Pi 3 B / Pi 3 B+ / Pi 2 A+ B+ / I2S

Audiophonics I-Sabre V4 DAC ES9023 TCXO Raspberry Pi 3 B/B+ / Pi 2 A+/B+ I2S

New version of the I-Sabre TCXO, its architecture is designed to allow you to have all outputs on the same side when the Raspberry Pi is coupled to the DAC. Connectors have been added to make the integration of the various components of a DIY player as simple as possible.

I-Sabre is now equipped with an advanced power management (ATX type) for the clean shutdown of the software solution used. These functions are managed by a PIC and allow different shutdown modes according to the needs (software or hardware).

This converter with new features is ideal for turning a Raspberry Pi 2.0, A+ or B+ into a high-definition file reader. Equipped with the famous Sabre ES9023, a revised schematic, and OS-CON capacitors, this DAC will give you a musical, dynamic sound rich in micro details.

Intended for the many software solutions dedicated to audio playback on this platform, it allows an easier than ever implementation for an incomparable result in this price range.


Key Functions :

  • I2C port.
  • Simplified assembly (no welding required).
  • Low noise control with heatsink.
  • Integrated on/off/boot management.
  • Dedicated connector for screen connection (direct pinout HD44780).
  • Dedicated push button connector (momentary).
  • DC 5.5/2.1mm jack input on the PCB.
  • Optimization of the integration of the converter and the circuit.
  • Advanced power management.
  • Low noise regulation of the power supply allowing a maximum power supply of 7.5VDC (2A).
  • Feeding the Raspberry Pi via the GPIO, feeding the Pi separately is no longer necessary.
  • PCM analog/digital conversion (24bit 192kHz max).
  • 2Vrms stereo analog RCA output.

Detail on the operation of the power management system

Power on process :

Press the button. The DAC turns on the Raspberry Pi. The LED flashes waiting for the "BOOT OK" signal from the Raspberry Pi (GPIO 22). This signal happens because a script changes the state of the pin once the Raspberry Pi is started. Once the signal is received, the LED stays on and the system is in a stable state.

Switching off from the button :

Press the button. The microcontroller detects the switch-off command. It sends a "Shutdown" signal to GPIO 17 to start the shutdown script. Once the Raspberry Pi is turned off, the button turns off waiting for a new power-up.

Switching off from Volumio :

Click on "Power OFF". The Raspberry Pi sends a "Shutdown" signal to GPIO 4 to start the shutdown script. Once the Raspberry Pi is turned off, the button will shut down waiting for a new turn on.

Reboot from Volumio :

Click on "Reboot". The Raspberry Pi sends a "Reboot" signal to GPIO 4 to run the reboot script. Once the Raspberry Pi is restarted, the "Boot OK" will come back and the button LED will be fixed.

Performant
J'ai acheté ce dac afin de pouvoir streamer mes sources réseau sur mon advance paris A12. Je l'ai testé pendant 3h et je suis bluffé par la qualité de ce dernier. Le seul truc embêtant c'est le power button qui clignote sans cesse. J'ai installé la dernière version de volumio et je ne sais vraiment comment faire pour laisser ce power button fixe.

I'm dissapointed. No volume control on volumio (version 2.x and 3.x). Huge problems with installing the power button. In Volumio 3.x, I was unable to get the button to work. Only the downgrade to 2.x helped. It gives 2 stars instead of 0 only because the sound quality generated by this DAC is very good.

Hi,
This DAC doesnt have an hardware built in volume control but you can always use the embedded to volumio software volume control.
This feature has been removed we are not responsible of that ...

Simplement excellent
J'ai acquis ce produit il y a peu, plutôt par curiosité et je ne m'attendais pas à une telle finition.

PCB épais et propre qui semble de très bonne facture. L'idée de l’alimentation filtrée qui alimente aussi le Raspberry est géniale car ça apporte une sorte de mode ATX.

J'ai aussi acquis le bouton poussoir et l'alimentation qui sont les compléments qui apportent un confort non négligeable et relativement intuitifs à mettre en œuvre (voir la doc dans le Wiki).

Question du DAC lui même, comparé à mon vieux et énorme Burr Brown, bien le Sabre l'enterre aisément. je suis surpris de voir ce PCB peu peuplé faire mieux que mon vieux gros Burr Brown des années 90. Des graves bien présents et des aigus très propres. Une belle stéréophonie, bref un régal. Pas d'acidité, ni d'agressivité.

Bref, me voici convaincu et très probablement enclin à d'autres achats sur ce site.

Excellentt!
Excellente qualité sonore. Facile à installer. Mon seul point négatif est que le bouton d'alimentation clignote et c'est ennuyeux. Voir le projet sur ma chaîne YouTube (hélas en anglais). https://www.youtube.com/watch?v=WJsnQq3P-kQ
