Measure Anywhere with the New AudioConnect 2 Audio Interface

AudioConnect 2 is the first laptop-powered portable audio interface for field measurements of headphones, infotainment systems, and other devices. Compact, lightweight and portable, it offers sample rates up to 192kHz, 2 input channels to power most microphones, head and torso simulators and test heads, 2 output channels, a headphone amplifier and more. And what’s more, it interfaces to your laptop with a single USB-C cable that also provides power!

Whether you need to test the noise cancellation of headphones in real-world situations, make in-car audio measurements while driving, or test your products in noisy environments. AudioConnect 2 is a simple and cost-effective solution.

It’s also reliable and cost-effective for production line and laboratory use, with simple operation, automatic configuration with SoundCheck, and an optional power adapter.
