3-2. Supplying DC power to the main unit
The LX-1000 operates on DC 8–36V power.
To supply power using equipment other than the included AC adapter(s), correctly follow the pin number assign-
ments in “5-5. DC IN power input” on page 22.
Equipment could be damaged if connections are made with incorrect pin numbers or voltage that exceeds the guar-
anteed voltage operating range is supplied.

ATTENTION
o
The guaranteed DC power supply operating range is DC 8–36 V. Never use a voltage outside this range. Doing so
could damage equipment or cause unexpected system shutdowns.
o
Do not supply power to DC INs until after securely connecting all connection cables between units.
o
Before disconnecting connection cables, turn off the power to the DC INs.
3-3. Installing amplifier modules

o
Amplifier modules can be added to the LX-1000 in single-slot units.
o
Always turn off power to the AC adapter and the DC IN before adding or replacing amplifier modules.
o
Install amplifier modules starting from slot number 1 in order without leaving any empty slots between modules.
o
When installing different types of amplifier modules, install AR-LXPA1000 modules, followed by AR-LXST1000 mod-
ules, and then AR-LXAO1000 modules in order from the lowest slot number.
o
Use the hexagonal socket screws included with the main and expansion units to securely install the amplifier
modules.
o
Attach blank panels to slots that do not have amplifier modules installed.
