Audio System Modular I/O
MIDAS DL I/O Card Options
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 conguration 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 dierent 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.
