What does it mean if the red power LED is lit on the controller, but none of the source LEDs
is lit?
This condition indicates that the controller is muted. Press the mute button to turn off the mute in
that zone at which point one of the source LEDs should light. If this doesnt solve the problem, and
you are using the paging and or doorbell hook-ups on the back of the MDS-6, disconnect these. If the
page audio inputs are causing the muting then try adjusting the page sensitivity pot in the inside of the
MDS-6 (see the owners manual). Sometimes it is necessary to reset the MCS-2 controller by pressing
the reset button on the controller.
When I am installing the MCS-2 controller, do I have to program each one individually?
No. The MCS-2 are equipped with a unique cloning feature. Once you have programmed one controller,
you then go to the other controllers in the house and press the Clone RX button. Then go back to
the programmed controller and press the clone TX button. The process then occurs automatically,
but you need to make sure that you are pressing the clone TX button before the others have timed
out, or reverted back to normal operation. In a large house, it may be necessary to do smaller groups
of controllers at one time. Future runs of the controllers will have an increased time out of 15 minutes.
Once I have programmed my MCS-2 controller, why does some of the source equipment not
work?
It is possible that the MCS-2 did not store all the commands properly. Try repeating IR commands with
the source remote through the IR window of the controller. If the commands pass through the system,
then go back to the controller and reenter the desired functions. If the source remote does not work
through the systems IR repeater, then you could have a defective emitter. If a different emitter does
not solve the problem, then possibly the modulation frequency of the sources IR is well above 40kHz
or well below 40kHz. Either scenario is fixable by adjusting the IR frequency trim pot (see the owners
manual p.9).
I am not using the page or doorbell functions of the MDS-6, but my system has a tendency to
mute.
The MDS-6 amplifier is equipped with a sensitivity adjustment for the page mute function. It is located
on the page /doorbell board inside the unit (see the owners manual p. 9). This trim pot could be set
sensitive enough that external noise is triggering the audio sensing circuit. This can be remedied by
turning the sensitivity pot completely counter clockwise. An external solution is to place a short wire
jumper across the Audio input signal and ground on the 12 pin input located on the back of the unit,
thereby disabling the audio sensing circuit of the MDS-6 amplifier.
