  • Page 10: Installation Electrical Considerations

    Page 10 MX Series — MX24 Operating Instructions Installation Electrical Considerations The MX24 has been manufactured to comply with your local power supply requirements, but before connecting the unit to the supply, ensure that the voltage (printed on the rear panel) is correct.
  • Page 11: Installation Mechanical Considerations

    MX Series — MX24 Operating Instructions Page 11 Installation Mechanical Considerations To ensure that this equipment performs to specification, it should be mounted in a suitable rack or enclosure as described below. Like all sensitive signal processing equipment, it should be kept away from other equipment which is sensitive to magnetic fields. Also, this unit may suffer a substantial reduction in performance if it is subjected to or mounted close to equipment which radiates high RF fields.

    Page 18 MX Series — MX24 Operating Instructions Console Select 1: Console Select: The Main Event! These two switches route the output of each quad channel set (depending on the Primary/Backup source settings for each set) to the main outputs. They may be mixed (so more than one may be active) and there is a brief programmed fade on enable/disable.

  • Page 25: Operating Your Mx24: Working With Failover And Redundancy

    MX Series — MX24 Operating Instructions Page 25 Operating Your MX24: Working with Failover and Redundancy The MX24 is capable of operating with redundancy on either of the two main quad channel input sets. Analogue is always the lower priority. If a Dante subscription is removed or the network is lost, the MX24 can switch to the analogue backup (MX24-D).

  • Page 27: Working Without Redundancy

    MX Series — MX24 Operating Instructions Page 27 Working without Redundancy If alternate signal formats are not available for your sources, the unit can be run entirely without redundancy or of course it can be mixed - one set with, one without as explained in the previous example on page 26.
  • Page 28: Operating Your Mx24: Headroom Monitoring System

    Page 28 MX Series — MX24 Operating Instructions Operating Your MX24: Headroom Monitoring System With up to 16 possible sources connected, monitoring them all would be virtually impossible, so the MX24 takes care of this by watching all incoming levels on all formats and alerting you to any channels that are close to running out of headroom.
  • Page 29: Operating Your Mx24: Gpi Configuration For Voice Evac. Systems

    Connect the MX24 to the network via its CONTROL Ethernet port, and run the utility app (available from the website under the MX Series product page) — if it’s the first time it has run, Windows will ask about allowing it through the firewall — be sure to tick all options before pressing “Allow Access”.
  • Page 30 Page 30 MX Series — MX24 Operating Instructions GPI Input 1 can be configured to either provide a system mute of the main outputs, or to route the mic input to selected outputs. Choose “Microphone Evac. To Main Outputs” to access the other available options as per the front panel - the mic gain, the filter setting, 48V and the routing required.
  • Page 31: Connecting To The Gpi Port

    MX Series — MX24 Operating Instructions Page 31 Connecting to the GPI port Connect to pin 2 for the microphone trigger or system mute trigger (depending on the configuration chosen), or pin 3 for the line in trigger. Isolated connections should be between the input pin and 0V to trigger, and +5V to clear.

  • Page 36: Connect To The Unit

    The loader will detect multiple units, but as there is no way to easily cross-reference IP addresses with physical devices, we recommend only connecting one MX Series unit to the network at a time when performing firmware updates, or power down any other devices temporarily.
