Project update time
For initial accounting purposes, the MDAC2 / FDAC has been called “DacX” – The names grown on me, so from now on the design will be referred to as the DacX – as I was never sure wither to call it the MDAC2 or FDAC…
Over the past month I’ve been working on the DacX mechanical and “System” design, its been uplifting to finally see the product take shape in its pending “physical” form – rather then a collection of “development” PCB’s…
Mechanically, 80% of the 2D drawings are complete – over the past month I’ve ordered over 60 “Small” items from China (from Screws / grub screws, washers, bearings, connectors, displays etc.) – only 3 items have arrived so far (China shipments are VERY slow ATM), I need to physically measure some of these items before I can complete the 2D drawings, then turn them into a 3D Solidworks project.
Once the 3D drawings are completed I will open 4 extrusion tooling’s, with possibly 2 more (6 custom tooling’s) – it’s an investment to realise the design to the quality I’m visualising.
A bigger investment is the custom front panel display, originally the vendor requested an MOQ of 500pcs at about US$100 – US$120 each, and that was a real concern, however after working with the vendor on the designs, the vendors CEO agreed to an MOQ of 100pcs – so a far less painful upfront cost, I honestly have no idea how many of the original development sponsors are still interested in the DAC.
A confirmed features of the design – the DacX can support upto 8 audio channels over a single USB link (192KHz max in 8 Channel mode) – these can comprise of any mixture of “Slaved” DacX’s or the far cheaper 2 channel digital expansion module DAC’s for those of you who are experimenting with Active speaker systems etc.
I forgot to mention the ADC module WITH Phono Stage (using MC step-up transformers) – this will be a x2 slot wide module (DacX has 5 rear expansion slots).
Also, later there will be an FM/AM/DAB + APTX BT module… Not HiFi, but people keep asking if I can support Bluetooth… pains me to offer a “Non HiFi” source on this DAC I’ve worked so long and hard on…
The Microprocessor module now includes USB input + option to install a CM4 module so there will be no need to purchase an USB module – the CM4 module option when installed and enabled can add streaming services such as Roon and Spotify Connect, Tidal, DLNA etc.
I’ve also been asked about R2R Dac, I will offer a R2R DAC board once the discrete 1Bit DAC and HiBit DAC boards are released – the DacX can be “upgraded” to any versions by the owner.
After all this time and work – its really nice to see the DAC’s “physical” outline coming together.
Once the 3D is drawn up, I will design the front panel PCB as its going to take a few spins to get the design correct.
Hopefully over the next month the items will arrive from China and the drawings can be completed – then I’ll issue the Custom display + extrusion drawings…. Taking us to the prototype construction stage.
