Buffalo III - flexibility without compromise.

[merlin el mago]

Connected again the B3 & still the same problem can't reach 5.25Vout

It's possible a cold solder in jumpers?

 

[NicMac]

sounds more like a short to me. What resistance do you measure on the BIII +/- terminals?
I would not power the BIII anymore before having located the problem.
Did you already use the 3V3 BiB's on BII or were you using Tridents?
Are you sure you did not connect the BiB 3V3 supplies to Vd on BIII?

 

[merlin el mago]

Only can reach 3.37 Vout with B3 connected.

Photos are needed.

 

[merlin el mago]

No photos needed, I fixed the problem: was inversed polarity in the Trident clock reg. Now is going on perfectly well, BTW I measured B3 power consumption & is aprox. 440mA as per Leon manual.

 

[necplusultra]

As a sidenote: one of my BII's with the Tridents, Mux and Toslink module pulls 450 mA from a Placid (CSS=+50mA), the other side with just Tridents uses slightly less.

How much total current for BIII, sidecar and toslink?

How much total current for BIII, sidecar and toslink?

Can't measure that as I don't have a BIII. According to the numbers specified it should be slightly above 500mA.

 

[NicMac]

Sidecar will add about 60 mA (20 mA/relay) when I2S/DSD is selected (relay coils powered). Zero consumption with S/PDIF selected.
To my best understanding....

Very close.

You were correct with the ~60ma when relays are active. When wired normally if they are active the SPDIF 4 module is switched off so it is not drawing current. When the relay are not active the SPDIF 4 is drawing current. (though I don't remember exactly how much off the top of my head). In other words the relay also switches power on/off to the SPDIF/4.

Is there a date decided for the next stampede?

Very neat Russ
There will never be the load of both SPDIF/4 module and the relays at the same time. Any significant "click/pops" when switching between the two?

None that I have ever experienced. That the nice thing about switching in the digital realm.

Why is the latest post deleted ?

 

[Russ White]

Only because we are trying to keep all support posts on the support forum to keep this thread a little more clean. It makes it possible to better track issues since they get their own thread.

 

[goodwill]

hi everyone, for the sidecar, trigger position GND-B-VD, can I connect with a SPDT switch to toggle between I2S and S/PDIF inputs?
thanks!

Russ,

Is there a way to get out an information about sampling rate frequency that DAC operates? I would like to use simple LED indicators that will show sample frequency of currently playing file.

JKC.

Not in a simple manner. You have to query a register in the DAC chip.

Is done by this software H i F i D U I N O

 

[LeonvB]

I think it'll be a standard feature of the AC2.

BIII bandcable

Where can buy 1 metre of bandcable could someone give me exact reference Mouser, Digi-Key, Farnell, RS, etc.
