Quick Installation Guide
Overview
The AUDIO/AMP over IP Transmitter, with Mic allows 2CH audio signals to be extended up
to 330ft (100m) via one (1) Cat5e/6 UTP cable in a point-to-point configuration. Point-to-
multipoint and multipoint-to-multipoint is possible by connecting several Transmitters and/or
Receivers to the same local Ethernet network. The Transmitter supports PoE (PD) if used
with a PoE (PSE) Ethernet Switch. These units support RS232 and IR transmission for
remote control of end devices. IR emitters and sensors are not included, but may be
purchased separately if required.
For the point-to-multipoint and multipoint-to-multipoint configuration the Ethernet Switch
must have Gigabit ports and DHCP Server capability and additionally support the IGMP
communication protocol for the multipoint-to-multipoint case. MuxLab recommends using
the Cisco SG300 Series Managed Switches. The MuxLab ProDigital Network Controller
(500811) is available to simplify the configuration and utilization of the 500755-AMP and
other MuxLab IP based products via an Ethernet web interface.
