NX242 versus NX241: What’s new ?
The NX242 Digital TDcontroller has been designed in order to provide total compatibility with its predecessor – the NX241 Digital TDcontroller.
What’s remain the same?
The DSP resources for both models remain the same, so new supported set-ups (i.e. firmware loads) will be compatible with the both the NX241 and NX242 TDcontrollers. For advanced set-ups and signal processing NEXO will release the NXtension Expander Board, which has double the available DSP resources.
MENUs and functions remain the same; no learning curve is needed to go from the NX241 to the NX242.
The same LOAD and NXWIN software is used to update both TDcontrollers. The transition is transparent for the user. Note however, that the NX242 can’t be flashed with LOADs prior to 2.21.
The appearance of the NX242 is identical to the NX241 except the model number. Therefore, you can mix both units in the same rack without aesthetic problems. Please note however that both NX241 and NX242 should have the same firmware revision (LOAD) to be phase compatible.
What’s changed?
The overall performance of the NX242 has improved significantly: 10dB more on the dynamic range, less distortion…
The layout and ground scheme of the unit have been totally revised to cope with the most demanding situations founded in the field (low and very high frequencies). The EMC protection on every input/output and the new ground structure makes the NX242 immune to interference far beyond the recommended values founded in EMC standards. As a result, there is no need for the earth lift function found on the NX241.
The input stage is truly floating and accepts important common mode offset (resulting from very long wiring or difference of ground potential between two connected equipments) without affecting it’s headroom (28dBu) and performance.
The NX242 Digital TDcontroller uses a switch mode power supply (SMPS). This SMPS accepts universal AC power input voltages in the range 90V to 264V, and requires no manual adjustment for voltages in this range.
The NX242 is designed to accept the optional NXtension
board with the ES-4 EtherSound interface and the CAI interface, whereas the
NX241 can only accept the CAI interface.
An
external LCD contrast adjustment is now provided on the NX242.
Download Last Firmware Revision
The Firmware update of the NX241 and the
NX242 is done the same way with the same LOAD file.
Please make sure that you use the latest
version of the NXWIN Downloader software.
The files needed to execute your download will be provided as a *.ZIP file. You will have to extract the content of this ZIP in a temporary directory using programs as WINZIP (not provided by NEXO). Once extracted you should have access to the following files:
· Two download (.DLD) files: the last official release version and the newly released version.
·
A README.TXT that will contain download instruction.
· WHATSNEW.TXT, which will inform you with all new features of the new LOAD.
· The DOS downloader program NXLOAD.EXE
·
The
WINDOWS Downloader program NXWIN.EXE and its help file NXwinhlp.chm

GeoT
Setup for
GeoT cabinet has been revised (new EQ).
PS15
Mono
Active PS15 + LS1200 subbass has been added.
Stereo
active PS15 in crossover mode has been suppressed. (The stereo wideband setup
remains the same).
Note :
the mono active PS15 + Sub and the stereo active PS15 are not within the same
family. To change from one to the other, you must reset the unit and depress
button A & B during the boot.
