Amanero into Ian Canada's i2S to Simultaneous PCB, no fS higher than 96kHz

[percival007]

Hi All,

I am using an Amanero PCB feeding IanCanada's i2S to Simultaneous PCB feeding two TDA1541A's.

I was using a DIYINHK PCB (which worked perfectly up to 384kHz) but this failed and the friend who I built the DAC for asked if an Amanero could be used.
The Spec's seemed as though it should but I cannot get it to work above 96kHz.
The three LED's still light at 176/192 but the Audio is distorted.
The i2S LED goes out at 352/384
The BCK coming out of the Amanero drops in Amplitude at the higher fS's so I am wondering if this is the cause. If so, any thoughts on buffering this ?

Ian says he has run his PCB with an Amanero OK.

Any thoughts appreciated.

The DIYINHK boards will hit 49Mhz for MCLK. Not so sure the kosher Amanero will. The knock-offs might but I wouldn't know.
See extract from the Iancanada board manual below.

MCLK

Hmm, thanks for this.
You have re0iterated what Ian said, and lets face it, he would know !!!

The only thing I thought strange was, that I could have sworn I used a DIYINHK board of the Spec'n shown in the attachment and it worked.

Their 768 pcb does indeed O/P 49 MHz (approx) MCLK but I don't think it was this type of PCB I used.
I will have to check more thoroughly.

Thanks anyway.
