AUDIO ROUTING COMMANDS
These commands route the Source 1 - 8 Audio Inputs signals according to the programming of the Source Selection buttons.
These commands are pre-configured in the “MZC88DEF1.etp” default project and would normally not need to be changed,
except for special situations. They consist of routing commands for the Source 1 - 8 audio and Page inputs plus an Audio Clear
command.
A common application for this type of routing would be to watch the Network, Cable or Satellite video feed of a sporting event
while listening to the home team’s local radio broadcast. (This is also a great use of the MZC-88’s dual internal tuners.) To watch
Satellite while listening to radio:
1. Left click the SAT key then the MZC-88 CMDs tab.
2. Open the Audio Routing Commands list and double left click ZONE 1 Audio 2. This puts Audio 2 along with Video
3 in the Command List. Refer to Figure 66.

3. Right click and delete the Zone 1 Audio 3 command (existing from the default project).
4. Left click the MZC-88 CMDs tab. Open the Built-In Tuner Commands List and Tuner Presets List. Double left click the
Preset tuned to the desired radio station, in this example, Tuner 2, Preset 10. Select and Drag the Tuner Preset command
up the Command List and place it under the Zone Video Routing command.
5. If not already in the SAT key Command List, add a Zone 1, Mute OFF command to the bottom of the list from the MZC-88
CMDs list, under Audio Level Commands.
6. Repeat this procedure for other Zones if desired and Download to the MZC-88.
With this programming complete, when SAT is pressed, Video will play through from Source Input 3 (SAT), MZC-88 Internal
Tuner 2 will switch to Preset 10 (local broadcast) , zone audio will route to the tuner AFTER the preset has been selected and
finally, the audio will un-mute, if muted.
HINT: Another option would be to place the ZONE 1 Audio 3 routing command under a function or numeric key, such as
the number 3 key. This would allow instant return to regular SAT audio after using the disassociated Tuner temporarily.
To set or restore Zone 1 Audio (and Video) routing commands, right click the zone number then select and left click “Place
Default A/V Routing Commands” in the pop-up. This will restore the default A/V routing commands for all sources in
the selected zone. Any A/V routing programming changes that had been made will be overwritten.
There are a number of variations for this type of programming that can be configured depending upon user requirement.
Using a different Source key, such as AUX, would allow normal audio/video routing to the SAT key, while using the AUX key
to route the Satellite video with audio from the internal tuner, with the above command sequence. With a dedicated Satellite
receiver or Cable box, additional macros could be built under the numeric buttons for custom ‘presets’ that would automatically
‘mix’ the various local team football, basketball, baseball, etc., TV and radio broadcasts.
