AC-MAX-24 USER MANUAL
INTRODUCTION
The AC-MAX-24 is a 24 I/O 2U rack-mountable audio matrix featuring dual RCA, TOSLINK, and Digital Coaxial
ports, as well as 2 AEX inputs and 2 AEX outputs, allowing users to return audio from decentralized sources
(such as a vinyl player) or extend audio out to a remote zone (such as a guest house or room with a local
soundbar).
The diagram below shows the basic application of the AC-MAX-24. The audio path can either come from the
audio sources directly or from remote audio sources via the AC-AEX-KIT as shown below.
Compatible Devices
AC-AEX-KIT
The AVPro Edge AC-AEX-KIT is a pair of PoC (Power over Cable) powered transmitter (AC-AEX-T) and
receiver (AC-AEX-R) modules that extend 2-channel analog and digital audio signals over standard
category cable via AVPro Edge’s exclusive AEX technology. The AC-AEX-KIT is ideal for sending and
receiving audio signals to/from decentralized devices to/from a centrally located audio distribution
system such as the AC-MAX-24.

AC-AEX-T
AC-AEX-R
(sold separately)
IMPORTANT:
Each AEX port on the AC-MAX-24 must be paired with an AC-AEX-T or AC-AEX-R for complete operation.
