Source Selection

The Source Selection Key is different than the other function keys. It provides control of the
Source On/Off, System On/Off and Play/Pause.
When a source button is selected, the following occurs:
The SOURCE is turned ON & begins playing.
If source = on-board TUNER, the last station listened to will begin playing.
If source = external TUNER, the last station listened to will begin playing.
If source = CD, then the 1st CD, 1st Track will begin playing automatically.
If source = SATELLITE, then the last (or current) channel viewed will begin playing.

Activating or Deactivating a Zone

Pressing the Source key turns the system on in the room you are in and also turns that source on if it has
not been previously selected in another zone (FIG. 51).
The indicator next to the source will light Red. Through Matrix’s own Dynamic Macro process, sources
that are muted or paused will be turned off after they are idle (not selected in any zone) for ten minutes.
Press the active source button again to turn the zone off.

Press any Source key
Solid RED = Only User, 3 RED Flashes = Multiple Users. This is important to know
because changing a source attribute (such as disc, track, preset, etc.) will affect all
connected zones.
