Alchemy Mastering has bought four NTP Technology DAD AX24 analogue-to-digital and digital-to-analogue audio converters as part of an upgrade to its facilities in Shepherd’s Bush.

“We’ve tested pretty much everything in terms of mastering grade digital/ analogue converters over the past five years,” said engineer Matt Colton.

The kit was supplied by NTP’s UK distributor, eMerging.
