I just bought a ’better’ DBX equalizer
model 2231, 2 channel, 31 bands (1/3 octave)
there are many absolutely identical copies of it by China makers, dbx were made in Malaysia, I chose EB831EQ via amazon because the units are already in USA, not just quicker, but if a problem, return it to Amazon (probably free return)
DBX Manual Inside the box,
they have a 1231, same 31 bands, but the 2231 is a step up, adds dbx Type 3 Noise Reduction.
Rack size: 1231 is 2U, 2231 is 3U, (5-1/4" high) the extra height needed for added features (probably a taller printed circuit board). It’s surprisingly heavy compared to the Rockville unit I sent back.
An advantage of extra height is the sliders are taller (longer more precise movement). The sliders have center ’0’ detent, of course you can bypass it, use Type III NR or not, ....
I don’t need it for my space, I have a hearing test scheduled, I’m sure at 75 that they will find something. Whether I need/get a hearing aid or not, there is the option of using the equalizer without the hearing aid to ’reverse’ what they find.
