4 ML4000 Sidecar User Guide
Combining Power Supplies for Backup
If you are connecting two sidecars then you can link the power supplies together for
redundant supply backup. One MPS14 supply is capable of running both sidecars
together should the other fail. You need to order the short 0.7 meter DC power cable
(part 002-584) for linking.
Note: Do not link the main console power supply to the sidecar supply in this way. One
supply is not capable of running both the main console and its sidecar should the other
fail. You should order a spare power supply with your console in this case. Make sure
the power supplies are positioned next to each other and use the same mains feed.
RS232 Code Update
A rear panel RS232 port is provided. This is used for loading new operating software into
the sidecar from a PC. It is not used for any other function. Check our Web site
www.allen-heath.com for details on the latest version of ML4000 operating software and
instructions on loading it into the console.
Note: The sidecar settings are archived using a MIDI or RS232 dump from the main
console. There is no need to archive the sidecar settings separately.
Important ! The sidecars and console must run the same version of operating
software. Check the web site for the latest version.
Audio Connections
The following information is
provided for reference only.
It is not necessary to wire
special cables to connect
the sidecar to the console.
Standard 1 to 1 wired
37way cables are provided.
The audio signals are
balanced and operate at a
nominal –2dBu line level.
