Setting-Up Advice

Earth connection

WARNING! THIS APPLIANCE MUST BE EARTHED.
The green and yellow wire of the mains cord must always be connected to an installation
safety earth or ground. The earth is essential for personal safety as well as the correct
installation of the system, and is internally connected to all exposed metal surfaces. Any
rack framework into which this unit may be mounted is assumed to be connected to the
same grounding circuit.

Mains setting

NEXO NXAMP Powered TDcontrollers exists under two references for each model:
NXAMP Reference
NXAMP4X1U
NXAMP4X1C
NXAMP4X4U
NXAMP4X4C
Each model applies to various safety standards only when use with the correct mains
voltage. Therefore, the amplifier won't start (or will stop working) if the mains voltage is
getting out of the following min and max limits:
NXAMP Reference
NXAMP4X1U or
NXAMP4X4U
NXAMP4X1C or
NXAMP4X4C
N.B.: The maximum amplifier output voltage is proportional to the mains voltage.
