Basic Keypad Functions
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. It also provides access to the “Favorite” source selection for the
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. 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.
Navigation Command Keys
The navigation arrays consists of 5 buttons Nav up, Nav down, Nav Left, Nav Right, Center and press
and hold Center. As an example these functions provide you with track, disc, channel, station and preset
up and down. The center position provides you with function user defined functions such as random and
repeat.
Muting the System
The keypads offer Dynamic Macro control for the sources used in the system.
For example the pause command: If a zone is accessing the CD player and you decide to mute the zone
or turn it off, then by selecting the source button, the CD player is paused. If there is another zone
accessing the CD player then a mute command is issued for the zone, and it is turned off or muted. The
system acts like a client server, distributing control on a “fair” Basis. This makes it easy for the system to
share the sources with all the zones.
All On/Off
ALL Zones ON - Press and Hold the active source button for 4 seconds.
ALL Zones OFF - Press and Hold Source button 1 & 2 simultaneously for 4 seconds (see the
Zone Control - On/Off section on page 46 for details).
Bass, Treble, Balance and SRS
By pressing and holding the volume up and volume down keys at the same time the Keypad will enter
into the setup mode for these functions.
Bass Mode
Bass Mode is the first action taken during the setup sequence. The source indicator lights will rotate in a
counter-clockwise direction indicating Bass Adjust Mode. Click the navigation button in the up direction
to increase the Base and down to decrease the Base. Clicking the navigation button to the left or right
will Balance the audio left and right. When you are satisfied with your adjustment, click the navigation
button in the center to save the Bass and Balance settings. Bass adjustments are provided in +/- 1dB
steps.
