implementers just use the chip as it is. But we tweak that technology within our own FPGA platform to make it more suited to our purposes: to get a higher sampling rate, certainly, but also to support the Direct Stream Digital (DSD) format. We’re still flying the flag for DSD. Some might question its validity today, but we believe there will be
SOLID GOLD
A RANDOM check reveals that leading US supplier Sweetwater Sound’s most expensive converter is the Solid State Logic Alpha-Link Live-R MADI-AES/EBU A-D/D-A model, featuring 24 balanced analogue inputs, support for up to 24bit/96kHz audio, word clock I/O and analogue metering. The Alpha-Link Live-R is a significant breakthrough for SSL, combining the company’s decades of expertise in
analogue signal processing with more recent digital know-how in order to breach the gateway of high-end digital conversion. The Alpha-Link Audio I/O series as a whole offers new options in multichannel audio conversion for the studio, live and broadcast sectors, with four models carrying 4-channel ‘SSL enhanced’ A-D and D-A technology and a wide range of digital audio formats on tap. Yours for $4,681.25.

of what’s physically possible, so the chip market is under scrutiny all the time.” Many manufacturers are now pulling their conversion
technology out of the mixer, or DAW, or whichever piece of the jigsaw they own, and placing it into rackmount products made available to the wider market.
