NXAMP4X1 VERSUS NX242: WHAT’S NEW ?NXAMP4x1 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 NXAMP4x1 are from the same family (same core) than the one usedin NX242 and on the NXTENSION board. Thus algorithms such as EQ will perform exactlythe same on both platforms to allow the user to mix NXAMP4x1 and NX242 with traditionalamplifiers at the same time.Level and latencyGlobal delays due to analog to digital and/or digital to analog as well as global gain areidentical on NXAMP4x1 on one side and NX242 with 26dB gain amplifiers on the other side(of course attenuators should be placed to 0 dB).Also when used with Ethersound networks (through the optional NXES104 board) theNXAMP has the same gain and delay from digital input to analog output than NX242-ES4with traditional 26db amplifier.Please note however that both NX242 and NXAMP should have the same firmware revision(LOAD) to be phase compatible inside a same setup.SoftwareBasic MENUs and functions are more or less the same; only little learning curve is neededto go from the NX242 to the NXAMP4x1.What’s changed?The same LOAD and NXWIN software are used to update both TDcontrollers andNXAMP4x1 Powered TDcontroller firmware. The transition is transparent for the user. Notehowever, that the NXAMP4x1 can’t be flashed with LOADs prior to 2_46, and must useNXWIN 4 software.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 10 OF 80
