Pre-Installation Checklist
The Audio 8x8 Matrix Switch provides a centralized switching center via UTP cables.
1. The Matrix Switch is used in conjunction with MuxLab hi-fi analog balun
(500028) and digital balun (500020).
2. The Matrix Switch is typically installed in a remote telecom room and is connected
to multiple video sources and display devices via Cat 5e/6 UTP. A MuxLab balun
is installed at each receiver/amplifier/audio source to support the connection to the
Matrix Switch via a Cat 5e/6 cable.
