5.2 An Example System
In a Multi Room Audio (MRA) installation, you can locate an Amplifier and
speakers in each room where audio is required. You would then run RJ45
cable across the building from the Matrix Switcher to each Amplifier, and
run shorter lengths of cable from the Amplifiers to the speakers.
Alternatively, you can locate all Amplifiers in a central location and run the
speaker cables across the building. In the example used to illustrate an
MRA system installation, a combination of these methods is used.
The example system consists of one Matrix Switcher, five Remote
Amplifiers and one Desktop Amplifier. Three of the Remote Amplifiers are
collocated with the Matrix Switcher. One Remote Amplifier is located on a
shelf in the Garage and another in a built-in robe (BIR). The Desktop
Amplifier is located on a desk in Bedroom 2 (BR2). Speakers are mounted
on walls using appropriate brackets. Wall plates are used in the bedrooms
and family room to provide local inputs. These can be used to connect to
the audio output of a personal computer (PC) or portable audio player.
On the following pages, diagrams are used to illustrate the C-Bus, speaker,
digital audio, IR target and shielded audio stages of the installation.
