Allo Isolator Isolateur Galvanique

Pollution of the I2S digital audio signals on Raspberry Pi 3 or SBC ALLO Sparky via its GPIO connectors is the main problem of poor reproduction of the 24bit and DSD High Definition files. The I2S Allo galvanic isolator provides the ultimate solution reducing the stability of the I2S signal on GPIO connectors.

Equipped with aALLO KALI (limited to 192khz) and a DAC for Pi3, here is the ultimate Hifi High End solution for Raspberry Pi 3 and ALLO Sparky.

The Allo Isolator is compatible with many DACs (master or slave) compatible GPIO PI3 by the 2 switch selectors.

To perfect the qualities of the Isolator ALLO, using a linear power supply 6.2-12V 3A or battery is a great upgrade:

Power Supply Audiophonics linear low noise

Warning: This product only corresponds to the Allo Isolator. Neither the Raspberry Pi 3, the Allo Boss DAC or the Audiophonics I-Saber ES9028 are provided.


  • Compatibility: SBC ALLO Sparky, Raspberry Pi3 / DAC GPIO master or slave, ALLO KALI (limited to 192Khz)
  • Galvanic Isolation I2C and GPIO
  • Power: Jack DC 5V 3A - 5.5 / 2.5mm or lithium battery.

j'utilise un raspberry avec picoreplayer depuis longtemps raccodé au minidsp sharc solution parfaite en 2x3 voies aux qualités indéniables par la suite j’ai acheté le module allo kali le bon qualitatif est énorme… par contre des craquements apparaissaient de temps à autres même des microcoupures ,vraiment détestable au point que j’envisageais de supprimer le module allo kali malgré la qualité apportée ,puis j’ai découvert le module isolator , la voilà la solution !!! pas vraiment de bon en avant pour la qualité audio ,des timbres un peu plus juste ,mais par contre fini les craquements et plocs en tout genre , une stabilité et fluidité à toute épreuve . Donc ce module est indispensable,
