Hello All,
Recently had reason to purchase a DBX 1215 graphic equalizer. While I am quite happy with the addition as it certainly helps music sound better at the lower sound levels I use more nowadays, I would like to upgrade it a bit. Have been unable to get a schematic from the company or find one online.
Would any of you have the schematic for this unit or know where I can find it?
Looking at replacing the cheap RC4560 opamp's with LM4562's and working on bettering the power supply a bit. I do know the LM4562 uses a bit more power than the TC4560 chips, so do want a better look at how the supply is designed and how much headroom there is for current supply. Design seems to be pretty decent with the limitation being the cheap op amps used.
Regards,
Greg
