Axia StudioCore™ Overview
StudioCore is an integrated console engine for Axia iQ, Radius, RAQ, and DESQ mixing consoles that combines audio I/O, a console power supply, a mixing engine, and a dedicated five-port AoIP network switch with PoE into a single fanless 2RU rack-mounted package.
StudioCore provides four selectable mic/line inputs, eight dedicated line inputs and outputs, and three digital inputs and outputs that are user-configurable as AES/EBU, S/PDIF, and USB Audio, which eliminates the need for an IP driver for stereo applications. It also includes two headphone outputs with independent DACs and built-in amplifiers, a built-in audio file player via USB data port, and four GPI/O ports. The Option Board slot provides the option to install a CAN bus board with three CAN ports, providing connectivity for up to three Axia iQ surfaces.
The optional Core Soft remote control solution provides HTML5 browser-based control of StudioCore, allowing it to function as a standalone mixer (with or without a hardware control surface), control a connected iQ surface, and serve as an in-browser monitor for the control room monitor output.
A second redundant internal power supply is optionally available.

Axia StudioCore In Depth
StudioCore is an integrated console engine for Axia iQ, Radius, RAQ, and DESQ mixing consoles. It combines an abundance of audio I/O, a robust internal console power supply (with a redundant supply available as an option), a full-featured 24-channel mixing engine, and a dedicated five-port AoIP network switch with PoE into a single 2RU rack-mounted package.
Its front panel boasts a 5” color IPS LCD touchscreen display that is viewable from any angle. Its UI provides complete local control of routing, I/O, and audio levels. Two dedicated headphone outputs with independent DACs and built-in amplifiers easily and cleanly drive low- and high-impedance headphones. Its fanless design ensures studio-friendly silent operation.
StudioCore’s easy-to-configure built-in 5-port Ethernet switch with PoE makes connecting to other compatible devices on the AoIP network simple and straightforward.
StudioCore provides plenty of input and output options for small- to medium-sized studios. There are four selectable mic/line inputs, eight dedicated line inputs and outputs, three digital inputs and outputs that are user-configurable as AES/EBU, S/PDIF, and USB Audio, which eliminates the need for an IP driver for stereo applications. Its generous Livewire+ AES67 stream capacity offers thirty-two inputs and thirty-two outputs. An eight-output monitor matrix system provides for flexible monitoring. StudioCore also includes a built-in audio file player via its USB data port and four GPI/O ports. Optionally, three CAN bus ports provide connectivity with up to three Axia iQ consoles.
The optional Core Soft license provides HTML5 browser-based control of StudioCore, allowing it to function as a standalone mixer (with or without a hardware control surface), control a connected iQ surface, and serve as an in-browser monitor for the control room monitor output.
