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.
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.
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.
This Buffer reclocker is compatible with the DAC Audiophonics I-Sabre ES9023, ES9018K2M and the majority of DACs that support HIFIBERRY DAC drivers.
