Waveguide and Trandsducer sources?
I received a parts quote from speaker exchange and am experiencing a bit of sticker shock, anyone know of another source?
thanks
Posted iTech M2 DSP parameters are not correct for BSS DSP
With the help of a fellow JBL nerd, we have come to conclusion that the M2 DSP parameters kindly posted earlier in this thread are not correct for BSS DSP units.
They are probably taken from a Crown iTech power amplifier, which the pictures also suggest, and they are not identical to the BSS parameters.
Tthe Crown iTech DSP and the BSS BLU-XXX DSP units do not work in the same way and do not use the same set of parameters for the M2 monitors.
The technicians at BSS also seem to confirm that there are indeed differences in the DSP function between them.
The correct BSS parameters contain 3 more PEQ's and most of the Q values are different. The are also denominated in octaves as opposed to Q in the iTech settings.
I have done some measurements on a BSS unit with both sets of parameters and the JBL original macro and the alternative set with additional EQ’s and altered Q values did mimic the JBL macro exactly.
I do not have an iTech to confirm but I’m pretty sure this is correct.
I will post the alternative list of M2 parameters for BSS units later today or tomorrow.
I have also done a full set of measurements (frequency/impedance) using 2451SL/2451Be,2453SL and 2430K on VTX and M2 horn (with and without passive filter) that can be made available if of interest.
Happy New Year
