MOTU 24I/O-CORE-SYSTEM

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.

Metering
The 24I/O's front panel is essentially a dedicated meter bridge for your hard disk recording system. Audio activity for every input and output is represented by its own five-segment LED bar graph.

Front Panel Power Switch
Useful in the unlikely event you wish to turn off your 24I/O. An interesting fact about MOTU Audio interfaces is that they are hot swappable. This means you can power off, plug-in, add and remove interfaces without turning your computer off or restarting. In fact, if you already have a 2408mk3 or other PCI-424 system, adding a 24I/O is as easy as plugging in an AudioWire cable.

24-bit analog TRS Input and Output
The 24 analog inputs and outputs are professional-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. In addition, CumixDSP provides continuously variable input trim with up to 12 dB boost per channel.

Word Clock I/O
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.

AudioWire
The 24I/O uses the second generation AudioWire we introduced with the 2408mk3. It is a high-bandwidth digital audio format capable of carrying up to 24 channels of 96 kHz digital audio in and out of the computer at the same time. AudioWire can readily handle the 24 simultaneous inputs and outputs of the 24I/O audio interface.

Power Supply
Like all MOTU hardware products, the 24I/O comes with an internal power supply and standard detachable IEC power cable. No wall warts or line lumps.

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.

Features:

• Expandable - connect up to four 24I/O units to aPCI-424 audio card for a total of 96 inputs and outputs. Use as manysimultaneous 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 exactI/O needs.
• ASIO drivers for Mac OS and Windows - providesmulti-channel 24-bit I/O for all leading ASIO-compliant audio software on bothcomputer platforms.
• Multichannel WDM driver - provides simultaneousinputs/outputs for all Windows audio applications that support standard WDMand multi-channel Wave drivers.
• 100% compatible with VST, MAS, Premiere, DirectX, andall other host-based native plug-in formats supported by today's popular audioprograms. Does not require proprietary plug-ins.
• Word clock - resolves to time code or any otherexternal time base via MOTU's Digital Timepiece synchronizer or any otherstandard digital audio synchronization device.
• Resolves directly to SMPTE time code (LTC) with fast lock-up and sub-frameaccuracy.
