QIO-ML24i

The Q-SYS QIO-ML24i is a network audio endpoint native to the Q-SYS Ecosystem, serving as a set of mic/line inputs that enables network-based audio distribution. The form factor of this product facilitates a high density of 24 analog audio connections in a standard 1U rack space, ideal for applications that require a large number of audio connections. The QIO-ML24i offers 24 mic/line input connections along with 8x8 GPIO ports for control. Dual Ethernet connectors provide optional network redundancy, and two of these products can also be installed in a redundant failover pair to guard against unexpected audio interruptions in critical applications.

Note: This topic provides an overview of the QIO-ML24i. For specifications and installation documentation, see the QIO Series High-density Audio Expanders product page on the Q-SYS website.
