Clipsal highly recommends using network cables of different colours to prevent connection of digital, C-Bus and LAN cables to the wrong connectors on the matrix switcher and amplifiers. Refer to Table 2.
Multi Room Audio Matrix Switcher and System 2.1 Installation Instructions AM/FM Antenna The RG6 coaxial antenna cable is terminated at the matrix switcher rear panel with a Type-F connector. When using the cable for AM radio reception, you must break the shield in the cable at some point away from the matrix switcher and associated equipment. Figure 5 shows the cable modification required for AM reception. It is not required if you are using only FM reception. Figure 5.
Multi Room Audio Matrix Switcher and System Installation Instructions • Avoid laying Digital Audio cables along side mains cabling, as electromagnetic interference (EMI) can disrupt the audio signal. • You can terminate the Digital Audio cable at a wall plate and run the cables inside the wall to the amplifier, or a wall plate near the amplifier. Then you can use patch leads from the matrix switcher to the wall plate.
Multi Room Audio Matrix Switcher and System 2.3 Installation Instructions C-Bus Network The MRA system's matrix switcher and amplifiers must be on the same C-Bus network. The matrix switcher and each amplifier has a C-Bus connection on the rear panel. The high power amplifiers and matrix switcher use C-Bus network cables that are terminated with RJ45 plugs. The Low Power Remote Amplifier uses a removable screw terminal connector. You may daisy chain C-Bus connections at the units.
