NXAMP versus NX242: What's new?

The NXAMP Powered TDcontroller has been designed in order to provide ascendant
compatibility with its predecessor – the NX242 Digital TDcontroller.

What's remaining the same?

DSP core

The DSP used in the NXAMP are from the same family (same core) than the one used in
NX242 and on the NXTENSION board. Thus algorithms such as EQ will perform exactly the
same on both platforms to allow the user to mix NXAMP and NX242 with traditional
amplifiers at the same time. However, computing ressources are higher on the NXAMP (see
further), thus some setup will perform only with this hardware.

Level and latency

Global delays due to analog to digital and/or digital to analog as well as global gain are
identical on NXAMP 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) the
NXAMP has the same gain and delay from digital input to analog output than NX242-ES4
with 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.

Software

Basic MENUs and functions are more or less the same; only little learning curve is needed
to go from the NX242 to the NXAMP.
The same LOAD and NXWIN software are used to update both TDcontrollers and NXAMP
Powered TDcontroller firmware. The transition is transparent for the user. Note however,
that the NXAMP can't be flashed with LOADs prior to 2_46, and must use NXWIN 4
software.

What's changed?

Integrated amplifier

The most notable improvement is the integration of the amplifier module that will simplify
the cabling from the user point of view but also allow a much more efficient integration of
loudspeaker controller with the amplifier needs. Thus the digital controller becomes also an
amplifier controller. This is not simply two units inside the same box, but a powerful use of
the DSP resources for both cabinets and amplifier being driven.
