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.

The front panel of the 24 I/O is a dedicated meter bridge for your hard drive recording system. Levels are represented in a 5 segment LED bar graph for accurate and precise recordings.

The rear panel of the 24 I/O has 24 analog inputs and outputs which are professional grade TRS(balanced and unbalanced) connectors. The input level can be switched via software in banks of eight to either 10dB or +4 dB, while the outputs operate at +4dB. In addition, CumixDSP provides continuously variable input trim with up to 12 dB boost per channel.


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

Features:

• Expandable - connect up to four 24I/O units to a PCI-424 audio card for a total of 96 inputs and outputs. Use as many simultaneous channels as host software and computer allow.
• 100% compatible with all MOTU Audio Wire interfaces. Mix and match MOTU audio interfaces (up to four at once) to meet your exact I/O needs.
• ASIO drivers for Mac OS and Windows - provides multi-channel 24-bit I/O for all leading ASIO-compliant audio software on both computer platforms.
• Multichannel WDM driver - provides simultaneous inputs/outputs for all Windows audio applications that support standard WDM and multi-channel Wave drivers.
• 100% compatible with VST, MAS, Premiere, DirectX, and all other host-based native plug-in formats supported by today's popular audio programs. Does not require proprietary plug-ins.
• Word clock - resolves to time code or any other external time base via MOTU's Digital Timepiece synchronizer or any other standard digital audio synchronization device.
• Resolves directly to SMPTE time code (LTC) with fast lock-up and sub-frame accuracy.
