The MOTU 24I/O audio interface is the solution for those with extensive collections of external hardware and sound modules to finally do away with a mixer and streamline their DAW setups. The MOTU 24I/O 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. MOTU fulfills the promise of host-based hard disk recording. You can record, edit, mix process, and master multitrack recording projects entirely inside the computer with a 24I/O.

The 24I/O Core System provides you with the 24I/O box and the PCIe-424 card and Audiodesk workstation software. The 24I/O box offers 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 24 analog I/Os are pro-grade TRS (balanced/unbalanced) connectors operating at either -10 dB or +4 dB. The input level can be switched via software in banks of eight inputs. CuemixDSP provides continuously variable input trim with up to 12 dB boost per channel. The 24I/O’s front panel serves as a dedicated meter bridge for your hard disk recording system. Audio activity for every I/O is represented by its own five-segment LED bar graph.

The 24I/O audio interface provides industry standard word clock sync on a single BNC connector that can be programmed for input or output via software. When operating as a word clock input, the word connector allows the 24I/O to synchronize smoothly with today’s digital audio studio. When operating as a word clock output, the word connector can be used as a master clock to drive other digital devices in your studio, such as a digital mixer.

MOTU’s PCIe-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 24/I/O 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. The PCIe-424 card is fully compatible with legacy MOTU interfaces originally designed for the PCI-324 card, so you can connect any MOTU PCI interface.

Plus, you get AudioDesk, a full-featured audio workstation software package for MacOS with features like 24-bit recording and real-time, 32-bit effects processing. The software includes multi-track waveform editing, sample-accurate placement of audio, a complete virtual mixing environment with up to 64 stereo busses, automated mixing, graphic editing of mix automation, scrubbing, trimming, spotting, crossfades, support for third-party effects plug-ins (in the MOTU Audio System and Adobe Premier formats), unlimited digital track bouncing (including effects and automation), and much more.

The MOTU 24I/O’s PCIe card allows you to take advantage of the next-generation functionality of PCIe architecture; the bus technology that will dominate the personal computer for the coming decade. The MOTU 2408mk3’s PCIe card allows you to take advantage of the next-generation functionality of PCIe architecture; the bus technology that will dominate the personal computer for the coming decade. Unlike older parallel technologies, PCI Express guarantees each device dedicated bandwidth to and from the system controller. PCI Express cards and slots are defined by their bandwidth, or number of data lanes - typically one lane, four lanes, eight lanes, or 16 lanes. At 250 MBps per lane, a four-lane slot can transfer data at up to 1 GBps and an eight-lane slot, up to 2 GBps - almost twice as fast as a 133MHz PCI-X slot at a maximum throughput of just over 1 GBps. The new PCIe-424 card can be installed in any PCI Express slot (regardless of its number of lanes). PCI Express delivers more than enough bus bandwidth for the 424 card, while ensuring that other PCI devices won’t "steal" bus cycles from the 424 card. PCIe means more bandwidth, less noise, and a vastly improved scheme for high-speed data transfers - just what you need for high-quality audio. PCIe means more bandwidth, less noise, and a vastly improved scheme for high-speed data transfers - just what you need for high-quality audio.

The 24I/O provides cross-platform compatibility with Macintosh, Windows 98SE/Me/2K/XP and all of your favorite audio software and host-based effects via WDM/ASIO/Sound Manager drivers. Or you can use the included AudioDesk workstation software for Macintosh, with 24-bit recording/editing and 32-bit mixing/processing/mastering.

The 24I/O can be purchased as an expander for an existing PCIe-424-based MOTU Audio System, or as a core system, which includes the PCIe-424 card and Audiodesk workstation software. Best of all, if you already own an older PCIe-424-based 24I/O or other MOTU interface, your existing hardware will work with the new PCIe card!
