Heritage Audio i73 Pro 固件更新支持 NAM A2

Heritage Audio have just launched a firmware update that makes it possible for their i73 Pro audio interfaces to host NAM (Neural Amp Modeler) A2 captures on their internal DSP. Free to all existing owners, the update allows users to track through high-quality emulations of guitar amps, pedals and outboard gear. 

NAM is an open-source technology that captures real amps, pedals, outboard gear and even full signal chains as neural models. A2 is its second-generation architecture, which was officially released on 2 June 2026 and was built from the ground up to deliver improved sound quality while using fewer computational resources. Thanks to the update, users can now host .nam files directly on the Heritage Audio’s i73 Pro’s built-in DSP, making it possible to track through captures without using any CPU resources or incurring any additional latency. 

Key Features

• Built-in loader for NAM A2 models/IRs and TONE3000 captures.
• Loads amps, combos, effects and outboard captures.
• Zero latency, processed on the interface’s own DSP.
• Access to hundreds of thousands of models from the NAM community.
• Free firmware update for i73 Pro interfaces available now.
• Built-in mixer also runs any Heritage Audio plug-in on the interface’s DSP, free for owners, plus any VST3 plug-in for monitoring.

“Our goal with the i73 Pro range has always been to make the front end of a home studio as good as it can be. With the built-in loader, an i73 Pro owner can play through any amp, pedal or piece of outboard in the NAM universe, with no plug-in, no extra device and no latency to worry about. And, as always with our i73 Pro community, we’re giving it to you for free.” — Peter Rodriguez, Founder, Heritage Audio
