Can I use Cuemix DSP for effects processing?
No. CueMix DSP is dedicated to monitor mixing. Host-based effects such as those included with Digital Performer are designed to run on your computer's CPU. However, Cuemix DSP allows you to integrate external effects processors with the same near-zero latency performance as a dedicated digital mixer. You can also combine Cuemix DSP monitoring with signals processed by host-based effects.

Can I use my original 2408 with the PCI-424 card included with the 2408mk3 core system?
Yes, older legacy MOTU Audiowire interfaces (2408, 2408mkII, 1224, 308, 24i, 1296) are fully compatible with the PCI-424. Even the new Cuemix DSP and synchronization features can be used with legacy interfaces.

Can I buy a 2408mk3 expander to use with my PCI-324 card?
No, the 2408mk3 only works with the latest generation design of the PCI-424.

Can I use the digital I/O on the 2408mk3 with my 96kHz digital mixer?
Yes. The 2408mk3 supports the TDIF and lightpipe 96kHz standards which halve the number of channels in order to accommodate the additional bandwidth. Therefore, a 2408mk3 supports up to 12 channels of 96kHz digital audio over TDIF and lightpipe.

Can I still use my MTP-AV or Digital Timepiece with the PCI-424?
Yes, use the sample accurate ADAT sync connector on the PCI-424.

What operating systems are supported by the 2408mk3?
MacOS 9, Windows 98SE, 2K, Me, XP

Will the 2408mk3 support OS X?
Yes, OS X drivers for the 2408mk3 are in development. You'll be able to download OS X drivers from the MOTU web site.

What is the difference between a core system and an expander?
A core system includes the PCI-424 card and Audiodesk software.

Can I plug my MOTU 828 or 896 Firewire interfaces into the PCI-424 card?
No. Like the PCI-324, the PCI-424 is an Audiowire interface only.

Can I plug my MOTU 2408mk3 directly into my computer’s firewire port like the 828 or 896?... without using the PCI424 card?
No. The 2408mk3 is an Audiowire interface only. It will only work when connected to the PCI424 card.

How many inputs and outputs can the 2408mk3 use simultaneously?
The 2408mk3 can use 24 inputs and 24 outputs simultaneously. You can choose from any combination of:
- 8 analog quarter inch (balanced TRS) inputs and outputs.
- Three banks of Tascam DA-88 "TDIF" connectors, 8 channels per bank.
- Three banks of Alesis ADAT optical "lightpipe" input and output connectors, 8 channels per bank.
- SPDIF stereo input and output.
