The UAC-8 uses high-end components such as the AKM AK5388 analog-to-digital converter and AKM AK4413 digital-to-analog converter. In addition, the UAC-8 performs 4-times upsampling during both analog-to-digital and digital-to-analog conversion. In other words, when the sampling frequency is set to 44.1kHz or 48kHz, the UAC-8 processes the signal at high resolution 176.4kHz or 192kHz.

For A/D conversion, this means less aliasing noise; for D/A conversion, this means increased clarity and fidelity.

In standalone mode, the UAC-8 can be used as an 8-channel mic preamp and analog-to-digital or digital-to-analog converter without being connected to a computer.

UAC-8 MixEfx is a free Macintosh and Windows compatible application designed specially by Zoom for the UAC-8. It provides a comprehensive onscreen mixer, with independent level, phase reversal, and panning control for each channel. UAC-8 MixEfx also allows you to freely route all inputs to all outputs and to create custom mixes. In addition, MixEfx features effects like reverb and echo, and complete mixes can be stored in three different memory slots, allowing instant recall.

The Zoom UAC-8 comes with a free download license for Sternberg’s Cubase LE music production software, providing not just the ability to capture incredible high-resolution / low-latency audio in every box, but to do spectacular things with it.

Take your recordings to a more professional level. Steinberg’s powerful and state-of-the-art audio software used by creators around the world now comes with every Zoom UAC-2 and UAC-8 purchase.
