The diagram above illustrates the basic setup of a multi-room audio system with dedicated source inputs. See the
notes below to understand the setup:
• The AV Receiver Zone 2 output is connected to the GLOBAL A input so that any sources attached to the
AV receiver can be played throughout the home on zones 1 through 4 at the same time. (zones 1-4 input
selectors are set to GLOBAL A)
• Each of the zones powering Rooms 1 through 4 are using the NORMAL (4-8Ω) output mode to allow for
a pair of speakers to be attached for left- and right channel audio in each zone. Individual zone volume is
adjustable through the inline volume controls in the rooms so that speakers can be turned off or adjusted to the
appropriate volume level as needed.
• Any source attached to the AV receiver can be set to play on zones 1 through 4, but there is no way to change
a zone to play a different amplifier input, so the streaming music player cannot be played through outputs 1-4
without changing the amplifier settings (difficult to do after installation).
• Zones 5 and 6 are both bridged so that more power can be delivered to a pair of large outdoor speakers on the
Back Patio. There is no volume control since the end user can simply adjust the source volume directly using
their remote control for the player (they already use it for selecting what the source is playing).
• In this application, a dedicated source has been connected for use on the patio, since bridged stereo would
require the use of both Global inputs, and the other zones would not be able to play both channels (because
they are not set to bridged, they would only receive signal and play audio on their left output channels).
• Sources are controlled separately and the amplifier may be used for any source at any time, so the Power
mode has been set to AUTO so that the amplifier will automatically turn on when needed. A 12V trigger cannot
be used in this case since two trigger inputs would be needed– one from the AV receiver, and one from the
streaming music player to allow for reliable operation.
