So, the new Pro Tools HD interfaces were released today. I have been wondering when Avid would release these, given that the last model came out almost 8 years ago. Here’s an overview of what’s new.

The HD I/O.

At first, these don’t appear to have changed much from the old models. For starters, the names have changed. The old HD interfaces were almost some variation on the 96 I/O and the 192 I/O (referring to their sample rate capabilities). The new interfaces are the HD I/O 8x8x8, the HD I/O 16x16 Analog, and the HD I/O 16x16 Digital.  The other big changes appears to be internal. New power supply and circuitry.  Better converters. Other than some expanded I/O, there really aren’t’ many new visible  features to sell on these, other than the promise of improved sound quality. But isn’t that the most important thing? Here are the types:

HD I/O 8x8x8

This interface  is named for its 8 analog inputs, 8 analog outputs, and 8 digital inputs/outputs (either AES, TDIF, or ADAT). As with the previous models of Pro Tools interfaces, there is an expansion slot for more I/O to be added later. These run about $4000.

HD I/O 16X16 Analog

This new Pro Tools interface comes with 16 analog inputs and 16 analog outputs. Note that these are not 1/4 inch jacks, but rather DB25 connectors that need to be broken out as a snake or to a patchbay. In fact, the analog I/O on all of these new interfaces is DB25, unlike the older models. Though you can exchange analog cards for digital ones, you cannot actually expand this model with additional cards. All 4 are already in use. These run about $5000.

HD I/O 16x16 Digital

You could probably guess this, but this new Pro Tools interface has 16 channels of digital I/O. This can either be AES, TDIF, or ADAT, depending on your needs and what gear you will be interfacing with. This unit has two expansion card slots for more I/O. These cost about $2500.

The expansion cards can be for an extra 8 analog inputs, 8 analog outputs, or 8 digital outputs.

I’ll be interested to get my hands on one of these to do a new vs. old Pro Tools HD comparison. I’ll let you know as soon as I have the chance! As always, contact me if you’re interested in beginner to advanced Pro Tools tutorials and classes, or for anything related to audio engineering.
