I see that a few months ago MiniDSP released a new product, the U-DIO8 Multichannel USB to AES-EBU or SPDIF interface.
Originally Posted By miniDSP
The miniDSP UDIO-8 is a pocket size USB Asynchronous interface with support for up to 8 channels of audio recording and 8 channels of playback. Inputs and outputs are digital and available in 2 versions (AES/EBU or SPDIF). A standard TASCAM pinout DB-25 connector to XLR (AES-EBU version) or DB25 to BNC (SPDIF version) is used for connectivity.

Thanks to 8 channels of high quality sample rate converters on all inputs, the UDIO-8 supports recording of any input rate (44.1~192k). On the output side, the digital output matches the playback sample rate selected in the driver.

The UDIO-8 is an ideal solution for high-resolution multi-channel audio, computer-based (HTPC) home theater, live sound, surround-sound mixing and mastering.
So it looks like finally there is a cost effective way to hook up a computer using a 5.1 channel digital output to the multiple SPDIF input of a Meridian Processor. A USB to SPDIF audio only alternative to an HD621!

I wonder has anyone tried this yet? I'll definitely be buying one later this year.

It seems to offer 8 discrete channels of digital output on BNC. The Meridian multi-channel processors expect multiple stereo channels on their digital inputs. If the device can combine channels correctly it would be rather useful, otherwise I cannot see a way of integrating it without further boxes. The AES/EBU outputs seem to be stereo digital feeds - is there a way of converting those to SPDIF passively?

May be all good - the Tascam interface is input and output so 8 plugs is 4 in and 4 out, ie hopefully 4 x stereo each input/output Tascam - DB-25_Pinout.pdf.

Needs confirming though.

Yes, it's four two channel inputs and four two channel outputs. The snake is available with XLR connectors (AES/EBU) or BNC (SPDIF)

In the software one can choose which of the 8 outputs is assigned to what channel (front right, rear left, centre etc.

The user manual is available at USER MANUAL

Thanks Ian.

The manuals and product specification seem to hint at that for the BNC/SPDIF option, the AES/EBU option is clearly that format.

Just to clarify, there's two output options, you specify the output at time of ordering. Either AES/EBU format on XLR or SPDIF format on BNC. As they say:

Quote:
To insure correct impedance matching, note that UDIO comes in two versions. (AES-EBU or SPDIF) with different internal PCB assemblies. Please make sure to select the correct format you'd like to use.


So the SPDIF output is genuine SPDIF format. You can't just change the AES/EBU snake for a SPDIF snake or vice versa.

The user manual only shows the AES/EBU connections.
