Zone Connections
The cables that run from each of the
keypads connect to the MRC- 8e/ 8.4e
via the same Molex connectors used
at the keypads.In this case,the
connectors will not already be installed
in the MRC- 8e/ 8.4e,and will be found
in a bag in the equipment box.
Again, please note: When stripping cable for use in the Molex connector,only strip away about 1/4 inch
(about 6mm) of the insulation from each wire.The complete assembly should not have any more than 1/ 16th
of an inch (or 1mm) bare wire visibly exposed from the bottom of the connector.
Audio Component Connection
Plug the audio cables from each source device into the RCA jacks provided on the back of the MRC- 8e/
8.4e.A switched power outlet is provided on the rear of the MRC- 8e/ 8.4e.Plug a power bar into the
switched outlet and then plug the power cords from all the audio sources into the power bar.
The power limitation of the switched outlet is 200 Watts which should be sufficient for the audio sources
in your system,however you should check the power rating of each device to ensure the total load does not
exceed this amount.
When the MRC- 8e/ 8.4e powers on or off,it will then power on all the related equipment.
The MRC- 8e/ 8.4e remains in a standby mode until the first zone is activated at which time the unit will
power up all components.Similarly,when the last zone in the system is turned off,the MRC- 8e/ 8.4e will
power down all audio equipment (after about 10 seconds) and return to standby mode.
Infrared Emitter Leads
Finally connect the infrared emitter lead for each audio source into the appropriate connector on the back
of the MRC- 8e/ 8.4e, and run the optical end of the emitter lead to the source device’s IR receiver window.
Quick Functionality Test
With all the components now wired in place you should be able to power each zone on and off from the
remote keypads.To test the system connections,activate one zone,and manually activate one of the audio
sources such as the tuner,or CD (since programming has not taken place yet),and move through each
zone and test that keypads respond to the on/ off and volume commands and that the source can be heard
at all zones.Basic functionality of on/ off volume up/ down and treble/ bass are functions that can be
performed without programming.
