MOTU 24I/O audio interface

MOTU 24I/O Overview

The MOTU Audio 24I/O interface fulfills the promise of host-based hard disk recording: to record, edit, mix process, and master multitrack recording projects entirely inside the computer. It provides 24 high quality, 24-bit/96kHz analog inputs and outputs in a cost effective, single rack space package, allowing you to connect and record from 24 simultaneous analog sources.

The 24I/O can be purchased as an expander for an existing PCI-424-based MOTU Audio System, or as a core system which includes the PCI-424 card and Audiodesk workstation software.

MOTU 24I/O Expansion

The 24I/O uses the same PCI-424 card that comes with the 2408mk3. You can connect up to four audio interfaces to a PCI-424 in any combination to create a system that fits your needs.

An ideal companion for the 2408

The 24I/O adds 24 channels of high quality analog input and output to your MOTU Audio system. With that much I/O available, you can keep the outputs of your synthesizers and outboard effects patched into your computer at all times. It is a snap to route the output via the PCI-424 Console Software.

MOTU 24I/O CueMix DSP

The PCI-424 card features a powerful DSP chip dedicated to creating a custom tailored monitor mix of up to 96 channels of 96kHz audio. Because the mixing takes place on the card itself, instead of making the round trip from the PCI bus to the host processor, the system provides the same near-zero latency performance as today's latest digital mixers. CueMix DSP completely eliminates the buffer latency associated with monitoring on host-based systems. Because the DSP is mixing for you, your computer's CPU is free for other tasks.

Cuemix DSP is the most flexible Cuemix ever, allowing you to mix multiple channels into multiple mix busses or directly assigned outputs. Manage your monitor mix with the intuitive Cuemix Console software included with the 24I/O.

Cuemix console greatly now provides independent level and pan controls for each input on every mix. Also, CuemixDSP does not limit you to four stereo mixes. You can configure a unique mix for every physical stereo output you have available. This means you can have up to 48 separate stereo mixes on a 96 output system.

Any MOTU Audiowire interface plugged into the PCI-424, including the original 2408, can take advantage of Cuemix's flexible monitoring.

MOTU 24I/O Legacy Compatibility

The PCI-424 card included with 24I/O core systems is fully compatible with legacy MOTU interfaces originally designed for the PCI-324 card. Connect any MOTU PCI interface, including the 2408mk3, 2408mkII, 2408, 1296, 1224, 24I/O, and 308. Mix and match new and legacy interfaces as you please. All connected interfaces can take full advantage of the PCI-424's CueMix DSP features.

MOTU 24I/O Setup Wizard

In a perfect world, your 24I/O system would arrive a week before your next recording project. But chances are, it will be only a few hours. That’s why the 24I/O includes a setup wizard for both Mac and Windows based systems. The Setup Wizard is an interactive application that helps you connect everything together. It even configures the 24I/O driver for you when you’re done! With the 24I/O, you’ll be up and running in minutes.
