Manufacturer's Description

Upgrade your rig with the rackmountable UAC-8, and add 18 inputs and 20 outputs to your USB 3.0-equipped Mac or Windows computer—even your iPad.* Plug in a microphone, line-level device, or instrument and start bringing your ideas to life, or take the UAC-8 onstage to enable high-res audio playback, all the way up to 24-bit/192k.

The USB 3.0 SuperSpeed transfer protocol used by the UAC-8, with a speed of 2.0 ms roundtrip @ 96kHz / 32 samples, is ten times faster than USB 2.0 and six times faster than FireWire 800. That not only ensures low latency, it provides a data stream that's unaffected by computer jitter (slight variations in timing), so there's no need to connect an external master clock source.

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.
