As for all NEXO systems, NEXO 45°N-12 is controlled, powered and monitored by dedicated NEXO
TDControllers:

NX242-ES4 Digital TDController provides comprehensive control of N12 line monitors in multiple
configurations. It allows EthersoundTM digital audio networking, as well as remote control for all units in
the network. It has 2 analogue / 4 digital inputs and 4 analogue / 4 digital outputs.

IMPORTANT

NX242 must be equipped with NX-Tension Card (NX-ES4) to access N12 setups

NXAMP4x1 and NXAMP 4x4 are Powered Digital Controllers, providing full control and amplification for
45N12 in multiple configurations. Both devices feature 4 analogue inputs and 4 speaker outputs. When
equipped with optional card, 4 digital inputs in EthersoundTM digital audio network format as well as
remote control for all units in the network become available.

For a complete description of these controllers, please refer to User Manuals. The NX242 and NXAMP
DSP algorithms and parameters are fixed in software and updated regularly: Please consult the NEXO
web site (www.nexo.fr) for the latest software releases.
