Chord Mojo(1) DAC-amp ☆★►FAQ in 3rd post!◄★☆

Was it pre implemented there for the purpose of the coming modules which chord has in place when they initial design the mojo ? Bluetooth ? Micro sd card modules ?


I don't think so, unless the firmware and (apparently) software already supports it.... I don't see a programming interface on the Mojo. Loading these devices requires some special programming pods and licensed tools, so we wouldn't be doing it at home anyway.

With the new intro Micro site like these for the mojo .

http://www.chordmojo.com

The creative sound blaster E5 sure got itself a worthy competitor , to go head to head with .
Ha now , chords should introduce the upcoming Bluetooth module to the mojo faster .

In my honest opinion , mojo is quite complete . Just short of a aptx enabled Bluetooth .

Oic , thanks understood .
But 1 thing for sure is , if it is there , then for sure it would serve a purpose . Which apparently , no one could figure out what its purpose for now ..

For Bluetooth ? Micro sd card modules ?
Sorry that's not correct the amtel chip is for the USB we have another consultant based in Italy who does this work for us.

Ok ,thanks understood .

Can u share with us here , when will be the aptx Bluetooth module intended for the mojo ready for the mass ?

Any heads up you could enlighten us ?

Many thanks

Is there a disadvantage to buying a Mojo from Amazon UK as an American?

 
 
  Yes the cost of returning it if you have a problem with it when you receive it.

 
True.  It all depends on your risk tolerance.  I purchased mine new from Chord / Amazon UK for $425, vs $599 from a local dealer, and I'm quite thrilled with it.  It depends if you're willing to accept the (small) risk for the discount.

This is true, I'm considering the 2qute in the future if I can import for a reasonable price. I'm not a fan of how VAT effectively get's included in U.S. retail, especially with the current exchange rates. I could justify the 2qute at around $1000 to $1200. Not at $1800 retail. Same with the Hugo. It could be around $1400.

But to be fair, Europe has the same problem with high value American gear like Schiit.

Notwithstanding JF's correction, above, just to add that there is, nonetheless, a programming port on Mojos PCB, albeit not for consumer/end-user use.

  Anyone know what this port could be for ?
 

 
I don't know much about electronics but looks like a pin set port to plug something into - apologies if I'm way off


Its the programming port so the FPGA flash can be re-programmed.

Ah there is a JTAG header... But you still need a licensed copy of Vivado and a Xilinx programming pod. Most people don't have that. Taking apart the product for a FW update isn't all that reasonable anyway. Maybe if they used one of those Digilent daughter cards (SMT2 I think) and brought the USB connector out updates would be more practical for the user. Still needs a license for the tools though.

What would really be nice is if the top level of the RTL was purely structural with nothing proprietary in it and the RTL for the submodules were encrypted and everything was released... Then we could really have some fun.

I think we already have plenty of fun with Rob's code, without the need for tinkering with it - and Rob's code is the result of some quite unique thinking and experience.
 
Doesn't mean anyone needs to idol-worship Rob - he's a normal bloke, but one who just happens to have a wealth of experience and some rather unique perspectives on ADC and DAC design.
 
Whilst there are many with knowledge of how to program FPGAs, there are far fewer with the sheer depth of intricate knowledge that Rob has in the aformentioned facets of digital signal 'construction' and 'deconstruction'.

I don't want to tinker with his stuff... Particularly because it's proprietary, I have no business tinkering with it. That's why I mentioned encrypting the source.

But I would have fun, for example implementing my own FIR filter at the output to change the frequency response. Or using a DDS based up/down converter to shift the frequencies and see what my favorite songs would sound like. Simple little weekend projects...
