NXAMP VERSUS NX242: WHAT’S NEW?NXAMP versus NX242: What’s new?The NXAMP Powered TDcontroller has been designed in order to provide ascendantcompatibility with its predecessor – the NX242 Digital TDcontroller.What’s remaining the same?DSP coreThe DSP used in the NXAMP are from the same family (same core) than the one used inNX242 and on the NXTENSION board. Thus algorithms such as EQ will perform exactly thesame on both platforms. However, new LOAD3_01 uses the full potential of the NXAMP’shigher computing ressources (see further), leading to discontinuing simultaneous firmwarerelease for both platforms.Level and latencyWARNING! Up to LOAD2_54, global delays due to analog to digital and/or digitalto analog as well as global gain were identical on NXAMP on one side and NX242 with 26dBgain amplifiers on the other side. In LOAD2_55 and above, to minimize global latencyespecially for wedge applications, the base latency of the NXAMP has been reduced to itsminimum, thus loosing the compatibility with NX242 family of products. Now withLOAD3_01 and above, the setups themselves offer different level, EQ, crossover points andprotection algorithm which cannot fit into older hardware like NX242 or NX242ES4.SoftwareBasic MENUs and functions are more or less the same; only little learning curve is neededto go from the NX242 to the NXAMP.LOAD3_01 does not fit other hardware than NXAMP. Please use LOAD2_58 aslatest version for NX242 (with or without NXTENSION) and LOAD2_48 as latestversion for NX241 (with or without NXTENSION-CAI).What’s changed?Note however, that the NXAMP can’t be flashed with LOADs prior to 2_46, and must alwaysuse NXWIN 4 software embedded with the firmware in the archive file.Integrated amplifierThe most notable improvement is the integration of the amplifier module that will simplifythe cabling from the user point of view but also allow a much more efficient integration ofloudspeaker controller with the amplifier needs. Thus the digital controller becomes also anamplifier controller. This is not simply two units inside the same box, but a powerful use ofthe DSP resources for both cabinets and amplifier being driven.PAGE 11 OF 103
