Buffalo III - SE
 
1 Attachment(s)
Hey Folks,

As you may know Brian and I have been busy prototyping and testing several new modules. Some of them are still in the works but one on them we are proud to announce now.

Say hello to the Buffalo III - SE (SE for Stereo Edition). The B-III-SE is basically a Buffalo III, with some cool new features and it was designed from the start to be friendly toward the most common DAC use case. Stereo and dual mono. Never fear we still plan on stocking the B-III for 8 channel apps, but this new DAC has some very compelling new features.
  • It requires no jumpers for setting it up in stereo mode. Mono requires minimal setup.
  • It has simple input options - including being able to switch between PCM/DSD and SPDIF remotely - no more signal carrying switch as we had on the B-II.
  • On board comparator for SPDIF input.
  • It is designed to utilize our purpose build Trident and the newly redesigned AVCC module(more on that later).
  • Even more configuration options via the on-board firmware.
  • Flexible input options including optional UFL connectors for master clock, and audio data/clock inputs.

Take a look!

And when do you predict this would be actually availabe for sale?

The motivation behind this new module is that we wanted to bring back much of the simplicity of the Buffalo II (this is actually much simpler) while taking advantage of the most significant new features of the Buffalo III.

We got a lot of feedback from users of the B-III - and one thing we hear consistently is that for the two most common use cases (stereo and mono with stereo being far the most common use case) the Buffalo III was a bit more work to configure than many users really wanted. In fact some people said they liked the Buffalo II better than the Buffalo III simply because it was easier to use.

We also got a lot of requests to make it easier to supply any master clock and to integrate coax type connectors, so we added UFLs and made it easy to disable the on board clock (just don't power it).

We also listened to past B-II users who did not like the "fiddly" (as one put it) switch for switching between PCM/DSD and SPDIF. In its place we have added a more sophisticated yet simpler to use BUSS switching system. No mechanical switching involved. All that is needed to switch between the two types of sources is an external switch, a controller, or a simple shunt type jumper (for fixed use). Very easy. :)

Also because we have freed up some of the port expander's I/Os we are able to offer even more flexibility in configuration.

We still retain all of the power of the on-board controller including volume control.

The result is the ability to create a very compact installation with fewer external modules required compared to the B-III.

Cheers!
Russ

We are getting a batch manufactured right now - so it will be a matter of weeks. I will let Brian fill us in on the details there as I am not exactly sure the turn around time.

Hi Russ, very nice!
Since this is stereo board, does the above mean you are taking advantage of input remap to free some pins for SPDIF input? (i.e., "unground" the input pins that were grounded in the BII?)

No - because I didn't intend this module to be used in that way. Also the datasheet is emphatic about grounding unused input pins.

We have a much better solution coming for muxing spdif signals into the BUF II or BUF III-SE. :) Very much like the OTTO-II but 4 selections instead of 2.

Would it still be possible to switch between S/PDIF, I2S and DSD?

RollE2k 18th September 2012 09:19 PM

And will that "mux" come at the same time as the "new" buffalo? When can we expect the new board? (since i'm looking to order pretty soon)!

Absolutely.

Yes - we are just ordering those boards in the next few days.
