Expander Sidecar USER GUIDE Publication AP4373 issue 2
Introduction The Allen & Heath ML4000-24SC Sidecar is the 24 mono input channel expander for the ML4000 console. It is free standing and does not need to be mechanically fixed to the main console. Interconnection is by means of multiway cables to link the audio signals and control logic. It is supplied with its own power supply unit independent of the console. The input channel strip is identical to the main console with all functions available. The groups and snapshots are controlled from the main console.

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.
