Reclocker I2S FIFO for Sparky and Raspberry Pi 44/48MHz 384kHz

reclocker allo kali

Outstanding precision

This is ALLO's KALI, a Reclocker I2S FIFO 44 / 48MHz I2S Reclocker that allows you to perfectly process digital signals and send them to your DAC. It is part of the range working with the ALLO Sparky SBC universe.

Indeed, each SBC (Sparky or Raspberry Pi) has a clock that is used to send digital signals to your DAC. The accuracy of this clock is very important in transforming the digital signal into analogue. SBCs very regularly use "first price" clocks to limit costs that are not suitable for audio use.

Example :
The Raspberry Pi3 features a 19.2 mhz clock derived from its BCM2835 processor. It cannot be clocked correctly at the frequency of 16 bit 44.1kHZ not being an exact multiple of 19.2mHZ.

It will be necessary to use a Recloker like the Allo Kali to bring a real precision to 44.1kHZ and 352.8kHZ or from 48khz to 384kHZ.

A better clock therefore means better sound and performance. The Kali will thus play this role of improving, thanks to its very weak Jitter clock fed by LDO and an ultra silent power supply.

Thanks to the KALI your music will "open up", your stage will be extended and more "three-dimensional". You will hear sounds, words and instruments that you did not previously hear when your digital signal was not processed properly.

COMPATIBILITY:

This version uses a Upsampling multiplier coefficient of X8 = 352.8kHZ for frequencies of 44.1kHZ and 384kHZ for mutliple frequencies of 48kHZ. It is therefore dedicated to DAC:

Es9016, Es9016, Es9018, Es9028pro, Es9038pro, AK4490, AK4495, AK4497, PCM1793/91/96/98, PCM1792/94/95, PCM5100/01/02, PCM5122/41/42, Wolfson 8740,8741,8742 CS4398.

For R2R and multi-bit DACs, the ALLO KALI 22/24Mhz version must be compatible with the following versions :

PCM1702, PCM1704, PCM1704, PCM56, PCM63, AD1865, TDA1541, TDA1543, TDA1387.
As well as the DAC AUDIO GD: R2R1, R2R2, DAC19, DAC 19 Singularity, DAC19 NOS, HE-7, R2R7, HE-7NOS, Master 7 Singularity, AK4399, AK4396.

hat size

The KALI ALLO must be powered by 5V / 3A via its jack plug, it cannot be powered directly by the SBC (Sparky or Raspberry Pi). However, it will power the DAC which will be connected to it.

This ALLO KALI Reclocker is HAT type and is therefore Raspberry Pi compatible. It is also Sparky SBC compatible.

C'est le Top!
DAC ISabre ES9028Q2M, avec le reclocker Kali et l'alim linéaire régulée, cable Mogami 3104 en bi-cablage sur des Tannoy D700. C'est le top.
Je n'aurais jamais cru que mes CD étaient aussi bons.

Bluffant !
J'étais un peu sceptique quant à l'amélioration que pourrait apporter ce reclocker. J'ai été bluffé. Je l'ai installé entre mon raspberry et mon dac I-Sabre DAC ES9018K2M J'ai énormément gagné dans la définition des aigus, les basses et médium sont encore plus propres et la scène musicale s'est agrandie, comme si les musiciens étaient plus "ecartés". La dynamique est elle aussi meilleure.
Un régal !

Not worth the money
Sounds with Piano really synthetic like mismatched frequencies.
AUDIOPHONICS I-Sabre V2 DAC ES9023 TCXO sounds much much better for less money.

Message from Audiophonics service
To our taste the Kali works very well with most of slaves DAC allowing them to deliver their full potential
