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.

Audio System Modular I/O
Midas DL451
The DL451 is a 3U 19” rack unit, which provides a maximum of 24 audio inputs and 24
audio outputs. It has the same user-congurable card format as the DL351 but has the
capacity to house up to 3 cards, which can be any combination of 8 analogue mic/line in,
8 analogue out (XLR), 8 analogue TRS line level in and out, 8 digital in and out (4 AES/EBU
pairs) or a 25 pin D sub card with 8 analogue mic/line inputs and 8 outputs.
Midi in, out and thru, and GPIO connections are supplied as standard. Digital audio
interface is via 2 AES50 ports, one of which can be congured as a spare redundant
connection.
The DL451 can be used with the Midas XL8 and PRO series of digital mixing systems, or as
a stand-alone AES50 audio interface in a Midas snake and audio distribution systems with
remote control via Ethernet.
