BII with TentXO3 and CDPRO2 don't lock

Not open for further replies.
hi guys,
I've a problem with my BII; it don't lock.The MUTE led is on and the LOCK one is off. I take the SPDIF from the Tent XO3 + CDPRO2. I read that BII lock only the frequencies of 256fc and higher. Do I've to put an ASRC between the XO3 and
the BII?

best
 
I' m talking about SPDIF not I2S, this is my set up:
-the PS is the Placid at 5.5V and 350mA
-all the voltages on the BII are correct, the leds are on
-the SPDIF switch is closed ( checked with tester), and the signals are connected to SPDIF
and GND terminal inputs
- all four the dip switches are in the ON position
-the BII sink only 260mA and not 290mA
-before the BII , my dac was the RAKK DAC II and everything worked fine
- I made a mistake when I powered the BII. I used a variac, and for a moment (less then
a second)the Placid out voltage was 5.8V. Can this damaged the dac?
Can you help me? I' m going crazy, cause I don't understating what goes wrong.
thanks
 
Ok, then as much as you might not like to hear this the problem is not with the Buffalo II.

You need to be sure that the SPDIF from your XO3 is clean standard consumer level SPDIF.

Your best chance to get support about the XO3 is to query its creator. I will not support it.

For now I would simply use your other source. 😎
 
Guido Tent tell me that I have to change the XO at 8.42 MHz with a one with double frequency. I don' t understand; he says that certain dac don't lock the lower frequency,
but why the CDPRO without the XO3 lock , and with it don't? The frequency it's the same!
Can you tell me why?
 
Today I mounted the Tent's module and the BII lock perfectly. I put a pulse transformer (Lundhal) at the BII' input, and this improved sensibly the sound. I like very much the definition , the sense of air and the soundstage.Also the bass have more extension.
I don't like the percussive bass,i.e. the drums. They lack impact and autority.Probably putting some capacitors between Placid and BII , I can solve the problem.
 
Hello Orelli

Given that the Buffalo reclocks on its own, how much difference do you think that the Tentlabs XO3 makes to your system?

It appears that you have used it with the clock, and without?

I am about to start a build with Buffalo II and a Cambridge Audio CD500SE. I have a Tentlabs XO3.2, but I am wondering whether to leave it out.

Your experience would be appreciated.
 
I suggest that XO3 is better than the direct Spdif output. I tried the CDPRO directly, and via the XO3 and the later is better. The XO3.2 is even better, cause it have the shunt PS. I like very much the pulse transformer at the input.

best, orelli
