ML5000 Service Manual 11
The Expander Sidecar
The Allen & Heath ML5000-24SC Sidecar is the 24
mono input channel expander for the ML5000
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. Up to two gooseneck lamps (part AL4061)
may be plugged into the rear of the meterbridge.
Note: This sidecar may be used with the ML5000
only. It is not suitable for use with other consoles or
as a stand alone console. One or two sidecars may
be connected allowing a maximum 96 input
channels. Do not connect more than two sidecars.
The following is supplied with each sidecar:
1x MPS14 Power Supply Unit with User Guide MPS14/n
1x Mains cord with moulded plug suitable for your local supply n = volts
1x DC power cable 2.8 metres long
002-583
3x 37way Audio Cables 2.8 metres long 002-617
1x 9way Logic Cable 2.8 metres long AL4155
Connecting the Sidecar to the Console
Diagram 1 shows the cable routing for connecting the sidecars to the ML5000. Refer to Diagram
2 for connecting one sidecar. Refer to Diagram 3 for connecting two sidecars.
Connect the three audio OUTPUT connectors 1 to the main console EXPANDER INPUT using
the three 37way 1 to 1 shielded cables provided. We recommend that you label the cables A, B
and C to avoid them being swapped if replugged. If you are connecting a second sidecar plug its
OUTPUT into the first sidecar INPUT connectors 2 . Plug the LOGIC connector 3 into the main
console LOGIC connector 1 for one sidecar, or 1 and 2 for two sidecars. Plug the power supply
DC cable into connector 5 .
Note: To maintain correct channel assignment do not reverse the interconnecting cables. Make
sure the cable plug locking screws are correctly tightened.
Turning the Console and Sidecars On and Off
Make sure the DC power cables and audio and logic interconnecting cables are correctly plugged
in and locked. Turn all power supplies on or off together. Alternatively, turn the sidecar supplies
on first followed by the main console, and turn the console off first followed by the sidecars. Do not
turn off any supply during normal console operation.
Note: For normal console operation make sure the rear panel RS232 switch 4 is set to its
NORMAL position. It will not function correctly if left in its RS232 position.
