Hybrid USB2/AVB audio interfaces with 48-channel digital mixers and AVB Ethernet networking capability
 
The 24Ai and 24Ao are hybrid USB2/AVB audio interfaces with 48-channel digital mixers and AVB Ethernet networking capability. They can operate as audio interfaces for a computer, as stand-alone digital mixers, as gateways to an expanded studio system, as components of an extended AVB audio network, or as capable hybrid devices performing all of these roles simultaneously. Together, they are designed to be a central component of a modern, high performance recording studio or live mixing platform. The following sections provide a brief overview of their main features and characteristics. State-of-the-art A/D and D/A conversion The analog section of each interface employs stateof-the-art 24-bit DACs or ADCs, which deliver analog recording and playback with remarkably high dynamic range at sample rates from 44.1 to 192 kHz. Complementary I/O configurations Each interface delivers an exceptional amount of analog and digital audio. In addition, the interfaces are designed to complement each other, and MOTU’s other AVB-equipped audio interfaces, to deliver a wide range of I/O options; you can mix and match several interfaces and operate them as a unified I/O and mixing system. The following sections provide a bird’s-eye glance of the I/O configurations offered by each interface in the MOTU AVB family. Each interface provides a variety of analog and digital interconnects, all active simultaneously, designed to provide everything you need for a wellequipped recording studio.
