modules to the facility input.

It is possible to connect up to 3 DM-1 modules to the facility input using a ‘daisy chain’.
When two or more panels are connected together in the following ‘daisy-chain’ format the
EQ on the DM-1 ‘closest’ to the host mixer should be used as the master EQ, while all
others should be left neutral. The following diagrams show how two units can be ‘daisy
chained’ for connection to the single facility input.

Note: If you require further information on an active module it can be found in its manual,
available from us upon request.

Power Supply Capacity

The existing MPA-626 can supply a total load of 54mA to external active devices and internal
modules. Care should be taken when using external active devices and internal modules with
the MPA-626 amplifier since exceeding the external load capacity risks the power supply cutting
out. The table below lists the current consumption of each compatible MPA-626 external active
device and internal module. Use this table to verify that the external load of your proposed
system falls within the specified limits.

If the 54mA load limit is exceeded the risk of temporary host unit failure will arise. If a failure
occurs switch off the amplifier and disconnect the remote modules, the amplifier should be left
off for approximately 30 seconds to allow it to reset. Check the wiring and total current
consumption of the external active devices before reconnecting the power and if the problem
persists contact our technical department.
