FEBRUARY 18, 2024 - Pro Tools Expert / Production Expert: In the article, "Why Do Brands Kill Off Perfectly Good Hardware? We Investigate," Mike Thornton (bio) details the many challenges pro audio manufacturers face when designing products that last.

In the "Good Design Can Extend The Lifespan of Audio Hardware" section of this article, Metric Halo design is given a shout-out for developing products that stand the test of time:

"However, good design can increase the lifespan of a product and in the pro audio industry, there is one brand that stands out in this regard and that is Metric Halo. Their interfaces have been designed so that key elements can be replaced so that when computer technology moves on, you only need to replace the port card, rather than the whole interface."

"The 3d Card Upgrade is a user-installable hardware and software combination that completely refreshes your Metric Halo devices for the next leg of the digital revolution. It replaces all the digital & computer interfacing on your hardware with up-to-date, cutting-edge implementations.

Anyone who has bought a Metric Halo interface in the last 18* years can upgrade it to modern-day specs.
