allo isolator + kali i2s reclocker input i2s audio gd NFB-1 2015 model
this combination works perfectly.
note! make sure that the switch on the allo isolator is on slave mode and put i2s output device in voumio on dac model on R-PI dac.
and separately give 5 volts for the raspberry pi and 5 volts for the kali reclocker and make sure the jumper is on.
I used a 30 cm long rj45 cat 5 cable.
I also connected the mclk signal to the audio gd nfb-1 015 dac.
note! if that does not work cut the mclk cable in the audio gd dac and make a ground connection, see also link diy audio gd.
recently everything in a different box built in, only the aluminum edge nicely finishing.
in the future I will use even better linear power supplies.
there will be a coax input to use a hifiberry digi + pro.
In the meantime I changed my setup, I sold the audio gd (i2s constantly gave a plop with start and stop music) an allo piano 2.1 came back for it.
built everything in a new cabinet and added an r-core and toroidal transformer and provides the new studer900 regulator with power.
also a 5 volt 3 amp regultor for the raspberry pi 3b + gets power from the r-core transformer.
the setup now consists of raspberry pi 3b + / allo isolator / kali reclocker / allo pioano 2.1.
in the meantime replaced the switching power supply for the 7 inch touchscreen with a linear, added an extra toroidal transformer, shielded all transformers, also used a better 5 volt 5 amp regultor for the raspbery pi, all cables better shielded.
a few holes in the top for heat dissipation and a usb input on the front.
on one side a larger heatsink for the studer900.
I am working with a project of my own. The output of the I2S from the Kali appears to contain a lot of ripple / spikes. Have I caused damage by hot connection?
I’m using the Allo Kali Reclocking unit with a RasPi3 feeding a digital I/O board. This provides AES/EBU, SPDIF, TOSLINK and I²S via HDMI (LVDS) acc. to PS-Audio-Standard.
No problems feeding I²S to my PS-Audio Perfect Wave DAC.
