MOTU 1248 Thunderbolt Audio Interface


The MOTU 1248 is a versatile 1U rack-mountable audio interface designed for studio recording, live sound, and installed sound applications. It features four mic inputs with switchable +48V phantom power, two hi-Z guitar inputs, 32 inputs, and 34 outputs. Additional I/O can be added through AVB networking. 

 

High Quality Audio 

This interface uses ESS Sabre32 Ultra converters for high-quality audio with a dynamic range of 123 dB and low THD+N. It connects via Thunderbolt for 128 in/out channels, USB 2.0 (3.0 compatible), or AVB audio network streams. A 48-channel digital mixer with DSP-powered EQ and compressor models is included. 

 

Flexible Signal Routing and Network Expansion 

The digital routing matrix allows flexible signal routing, and an AVB Ethernet port provides low-latency networking. You can expand the system with a MOTU AVB Switch for up to 512 channels. Control and monitoring can be done via a web application on various devices connected to the local network. 

 

Quick setup presets are available for different applications and can be customized using the digital routing matrix.
