Audio connections on analogue consoles are comparatively inexpensive, a mixing console will have as many insert points and direct outputs as there are input channels. Not so with digital mixing consoles.
Insert points and direct outputs require A-D and D-A converters, as well as physical connections, so most manufacturers limit the number of these to a mere handful of options. One advantage of MIDAS’ network approach to digital mixing is that the number and configuration of I/O’s can be easily expanded for complex applications, but easily streamlined for less demanding, more straightforward duties.
The modular construction of the I/O system means that the right number and correct type of connections are always available, and always in the right location. MIDAS modular I/O cards are interchangeable between different hardware housings and all feature MIDAS audio performance and reliability, plus some extended usability features such as the connection locator LED found on all XLR I/O cards.
There are 5 different I/O cards:
