14 ML4000 User Guide
Connecting the Power Supply
The ML4000 console range is supplied with the
MPS14 power supply unit. A second MPS14 may
be connected through the first as a redundant
(backup) supply.
Before connecting please read the IMPORTANT
SAFETY INSTRUCTIONS printed at the front of this
user guide and the warnings printed on the rear of
the power supply. Also read the user guide
provided with the power supply. Heed all
instructions regarding the installation and ventilation
requirements of the unit.
Connecting Mains Power
Check that the correct mains lead with moulded
plug suitable for your territory has been supplied
with your console. The MPS14 accepts mains
voltages within the range 100-240V AC without the
need to change any fuses or settings.
Make sure that the IEC mains plug is pressed fully
into the MAINS INPUT socket.
Connecting the DC Cable
Plug the cable into the power supply DC POWER
OUT 1 socket. First align the locating lugs, press
the plug into the socket, and screw on the locking
ring to hold it firmly in place. Plug and secure the
other end into the console DC POWER IN socket.
If you are using a second ‘redundant’ supply as a
backup then connect the short cable to both power
supplies. Connect from the DC POWER OUT 1
socket on the backup supply to DC POWER OUT 2
on the main supply.
Turning the Console On or Off
First check that the mains and DC leads are
correctly plugged in and secured. Turn on the
power supply using its front panel mains switch.
The console must be connected to the power
supply before turning it on. Failure to do so will
result in the unit powering up in protect mode. Turn
off, connect the console, and turn on again.
To avoid loud pops in the speakers make sure that
the connected power amplifiers are turned off
before switching the console on or off.
WARNING
: To avoid damage to the
speakers always switch the power amplifiers on
last and off first.
