Dear kp93300:
Could you please remove this iso board, and check the sound again see if hiss still appearing ?
thanks

Hi peterpopo,
I power the input segment of the iso7240 by another power power supply with 4.7 V dc . the hiss disappeared and sound quite nice in my test speaker but there is intermittent dropout that may be due to cold joint. will troubleshoot after work tonight.
i think the 3.3 v from the amanero combo board is not enough to power the isolator.
thanks

I redo the joints and the intermittent drop out persisted.
Could the drop out due to intermittent unlocking of the i2s signal ?
Any suggestions anyone ?
Have anybody use this isolator successfully with the Buffalo 2 dac ?
I may populate the other board at a later date if there is no other suggestions .

I have tried the IL715 before with no negative effects in my setup: Experiments with NVE IL715 Isolator | H i F i D U I N O

Someone have one or two components set that don't use and want to sell?

 

[kp93300]

thanks glt for the helpful post.
I alos used dedicated power supply for both the input and output pins of the isolator.
I have not populated the other board and awaiting more feedback from othe rusers of this board.

Received the pcb's today. Thank you diyhnk!
Anybody running this board yet?

 

[merlin el mago]

Yes, works like a charm🙂

 

[neskor]

Hi

Could someone post pics of his build 😉
Merlin are you the one who will ?
Thanks

Hi some news
Finished my board, I've soldered all parts as mentionned in Post#1.
The Amanero stick works fine, but used with the isolator it gives no sound 🙁
I've missed something, but don't know what ?
Do I need to supply 3.3v ?
I've populated U2 & U3, do both chips needed to be removed.
Thank you for your help.
Regards

Phil

Do you have to supply 3.3V from USB-I2S converter to the input of the isolator & 3.3V at the output of the isolator from the DAC.

 

[merlin2069er]

Ok, I've sent a payment for a couple of boards.

 

[tubesguy]

Got my boards today. Thanks again.

Hi merlin

Thank for the tip, forget to supply 3.3v from DAC...
Works perfectly now !

 

[merlin el mago]

I'm glad to hear that works OK, how about the sound?

 

[korben69]

Sound is more detailed, deeper scene, very clean soundstage.
I've taken 3.3v from Subbu DAC V3, unused WM8804 PSU line.
Forgot to mention that in my previous pic I've mismatched connector soldering side...
