Frequently asked questions
•
After connecting the Wallunit the text ‘Musicall Please wait…’, and after some
time ‘No data from host…’ appears?
Check the voltage on the wallunits connector with the wallunit connected.
In a normal situation this should be approximately 24Vdc. On a very long
cable length this could be slightly lower because of the voltage drop over the
cable. The wallunits will work up to 13Vdc.
When the voltage without the wallunit is 15Vdc, it is very likely that the cable
is connected to the outermost pins at the matrix side. These two pins are to
be used by the MRA instead!
•
When I select the local input, and adjust the volume I can hear a high-pitch
buzzing sound?
When the MRA and wallunit cable are in parallel they will interfere with
each other. It is recommended to use a shielded cable for the MRA and a
separate cable for the wallunit.
•
What are the maximum cable lengts?
The maximum cable length for connecting the MRC wallunit is 1500 meter.
The maximum cable length for connecting the MPC console is 200 meter.
The maximum cable length for connecting the audio input is 200 meter.
