John - is there a list where I can check what payments I've made so far please?
Cant seem to track them all in my paypal statements.
I am pretty sure I've paid up till FDAC L3 and want to pay for the ADC as well, but wanted to check if I need to pay any more installments as well
 
John
Can you clarify the following re the new spec sheet:
1. It mentions using DSP in the future for room eq but does not mention using DSP for active crossover duties. Will the latter be in place from the get go?
2. Previously you indicated that you would not be able to use an SD card as a music source, but it now says for recording/replay. So will you be able to store music files on such a card and play back from it ? Also why is it it limited to 32 GB?

I've lost track of what I've paid. I think I've paid the L2 installment- can you confirm. I'm a Fusion owner but not sure at what stage that comes into play?

Nothing public as most people prefer to have there information kept confidential.

Just drop Renata an Email of you have lost track :) it has been a while....

I've Just confirm with Renata that you have fully paid up todate to L2 - so L3 / L3 MM/MC pending if required (L3's the ADC version).

From a Hardware perspective the units will be DSP ready for Room EQ / active Crossover - but we are at the mercy of MiniDSP once the units are in production.

2. Previously you indicated that you would not be able to use an SD card as a music source, but it now says for recording/replay. So will you be able to store music files on such a card and play back from it ? Also why is it it limited to 32 GB?

With Jarek expertise once he joined our little Lakewest design team has made it possible to include an ARM CPU with an SDcard slot etc. The ARM CPU SD controller can only support upto 32GB. It is only meant as a storage device for local recording sessions / test file playback etc. not as a full blown music server (although 32GB holds upto 50CD's)....

I've lost track of what I've paid. I think I've paid the L2 installment - can you confirm. I'm a Fusion owner but not sure at what stage that comes into play?

Please send no funds (You have paid to L2) - IIRC I still owe you so I'll confirm over Skype and add you to the L3 list (MC/MM option)?
 
I guess this is the connection to the Shell - and its hard to say as it depends on the systems Grounding - I suggest trying first without the any connection to this pin.

Hi John
The tuner is not grounded to mains if it makes any difference.
I have paid the L3 Development £ 100.00
Thanks for all your good work
 
Channel D specialise in turntable / RIAA transcription software (Pure Vinyl) for Apple OSX machines they also have a range of MC / MM Pre-amplifiers.

The FDAC's internal Phono stage emulates the feature set of there Seta Model L / Model H Pre-amplifier (Gain settings / RIAA and Non RIAA modes) etc.

Thank you :)

As for the Grounding with Tuners you never know what's going on with the External Antenna Ground....

Hi John
There is no grounding on the aerial either so think its best I dont ground the XLR case.
Sorry if I have been a nuisance, I know you are busy
 
We are not certain at this time... We might use the MDAC style AC adaptor - safety certifications runs to about US$5K, something we can avoid if we use an external adaptor...

We are also aiming for a small footprint DAC - an internal transformer significantly increase the size.... we are still "Up in the air" about the FDACLite PSU.

Jarek's here tomorrow - we will better define the FDACLite.

I think the last spec sheet led me to believe that all FDACs would share the same internal PSU. Please don't use something like the MDAC PSU, the long fixed cables are pain in the ass ;)

Maybe there are nice linear power supplies with sockets to fit custom length cables. Or even better, you come up with an internal PSU :D
 
Hi John, all

Long time no post in here!
Crazy, exciting developments for the FDAC!

If i read the latest specs correctly, there will be a a processor, a card reader, 2 usb ports wifi dongle possibility (do you supply it as well?), ethernet… (sounds RPi-like, correct?) and future internal squeezebox support.

Does this hint at a future LMS client? FDAC as a DAC-streamer (further, further down the road)?

I understand all this would happen in the future, so, no rush for answering!

Pierre
 
Apparently you missed this in the specs: "Future internal Squeezebox Touch support via software update".

Yes, future LMS client :)
 
Pierre,

Not so much RPi as the RPi the hardware is too compromised and not open - but based on the open hardware Beaglebone Black:-

https://en.wikipedia.org/wiki/BeagleBoard#BeagleBone_Black

We are using are own optimised hardware design (not a BeagleBone PCB).

I guess we will recommend or supply "at cost " a recommended WiFi dongle - Jirij here warned me that USB WiFi dongles are poorly supported in Linux - so its best to provide a tested part.
 

Corr!....its getting exciting again....I'm in for the FDAC-L3....L3 development fee payment sent:D ...I don't have a TT or any vinyl now otherwise I would have definitely gone for the L3 MM/MC option.

John, on the payment options it should say:

'FDAC Slave units (L2 or L3) Development fee £300.00 GBP' and NOT : 'MDAC2 Slave units (L2 or L3) £300.00 GBP

I may 'need' (I always 'want') some slaves....so I'm considering this for now!
 
Hi John,

As Renata confirmed last March I was then paid upfront up to Level 3, I have now funded the FDAC L3 MC/MM additional optional development payment. Keep up the good work.

Best wishes to you and Renata.

Roger.
 
Hi JohnW,

FDAC L3 and MM/MC payment made. The spec looks great. Not sure I will need MM/MC but I like to keep my options open.

Also, I would greatly appreciate an update on DETOX box.

Thanks for all you hard work.

Just made remaining payments via paypal - for both L3 and MM/MC

Thank you for the Payments - prototype will be completed by the end of this month - the Chassis will be shipped from China around the 15th (CNY from 15th Jan to 15 Feb).

It gives me a month to get any updates required and the paperwork together - I plan to fly to China early March to arrange Detox production.

We also plan to have the FDAC Digital PCB prototyped by March.
 
Hi johnW,
My understanding is that the std in front of "Optional CNC Full internal electrical screening Chassis" means it will not add cost to L3 mm/ mc while for L3 it can be purchased as an add-on. If this is correct can you please provide an estimation of the cost to have the cnc chassis on an L3 version?
Thanks
