Hello, I want to know about the application scenarios of multi-channel DACs and are there any special requirements? I personally have a benchmark DAC2008, a very good old DAC (using TDA1547), it only has 4 AES inputs and 8 Analog outputs, no other functions, technically, we can indeed do 8-channel DAC, according to our current understanding of ES9038PRO, we can achieve 8ch, each channel can reach -123dB (@5Vrms)
Hello SMSL_Liu,
Let me join our OP
@B&WTube in greatly welcoming you on this thread!
I have OKTO DAC8PRO (one ES9028 for 8-Ch DAC processing) using in
my multichannel multi-driver multi-way multi-amplifier "stereo" project consists of five SP drivers in L and R,
i.e. sub-woofers (SWs), woofers (WOs), midrange Be-squakers (Be-SQs), Be-tweeters (Be-TWs) and metal horn super tweeters (STs). You can find
my latest system configurations here (post #636 on that thread).
Although my system is actually 5-way 10-Ch stereo, OKTO DAC8PRO gives maximum of 8-Ch DAC processing so that I inevitably drive
Be-TWs plus STs by the 7th(L) and 8th(R) channels of DAQC8PRO (and further splitting the signal in analog SP level into separate two amps for Be-TWs and STs). This means that, even at present, I would like to have HiFi 10-Ch USB-DAC to replace my OCTO DAC8PRO...
I am further planning to add a few SP drivers (and amps!) in this system which should be fully in sync with other SP drivers currently singing in full sync by DAC8PRO. (Very fortunately, the digital software XO/DSP/EQ "EKIO" I am using have no limitation in numbers of output channels.)
In my rather "extreme" multichannel system/project, therefore, I would like to have simple HiFi 16-Ch multichannel USB-DAC of similar performance and spec of DAC8PRO; I do not need any XO/DSP/EQ capabilities in such 16-Ch USB-DAC since I do XO/DSP/EQ in upstream digital domain within PC.
I do believe you at SMSL have enough knowledge and technology in developing such 16-Ch USB-DAC using two of ES9038PRO with common clock and XMOS firmware.
As I wrote in
my above post #143 on this thread,
Danville Signal has concrete plan for developing/manufacturing 2-In 16-Out USB-DAC+XO/DSP/EQ in one box using two of ES9038PRO (I believe so) in it. The coming Danville's
dspNexus 2/16 will look like onebox alternative for the extraordinary expensive Trinnov Altitude 32; we (at least myself), however, do not need all of the XO/DSP/EQ functions, and we/I need only the fully sync 16-Out (XLR balanced) excellent HiFi multichannel USB-DAC unit.
For the
possible SMLS's simple HiFi 16-Ch USB-DACs, of course we need reliable low-latency USB ASIO driver (in Windows PC, Linux, and MAC) which should recognize all of the 16 channels of the USB-DAC as output channels looking from digital software crossover XO/DSP/EQ software in PC through single USB 2.0 cable connection.
Thanks in advance for your kind attention and consideration.

As
@somebodyelse kindly pointed
in his post below, I would be really happy if I can use two of your possible 8-Ch USB-DACs (XLR balanced out), Unit-1 and Unit-2,
having clock sync mechanism between them, and if the OS and PC software would recognize (by your possible ASIO driver) all of the 16 channels independently as the output channels (hopefully by single USB 2.0 cable into the Unit-1).
