NL Series -RV Option


Reverberation Time Measurement

By adding the NX-42RV program to the NL-52/42, the -RV option enables reverberation time measurements to be performed. The measurement method used for this is the interrupted noise method.

This program allows storage of reverberation time decay curves, T20/T30 calculation,Txx calculation (reverberation time calculation based on a user-defined interval) and averaged reverberation time results displayed on the SLM screen.

  • The NX-42RV is supplied on the 512 MB SD card.
  • The 512 MB SD card can be used as a memory card after installing the program.

Please Note: The Rion NX-42RV card can only be installed on an NL-42RT/52RT. ie. NX-42RT must already be installed.
