Hi All,
I've recently acquired a used Behringer UB1204 FX Pro mixer & considering modding it by replacing all the JRC4580 ICs with NE5532. My confusion is that bI am not sure if opamps used in the mixer are SOP or SOICtype! So can anyone who has already done this mod kindly tell me as to which type IC package I should buy.
My other confusion is that NE5532 has only 10MHz GBP,compared to 4580 which has 15MHz GBP! However,I've extensively used Texas NE5532 in most of my projects & find them very musical. I've also considered using LM4562's, but these don't seem to have the "musical grit" as the NE5532,especially on guitar preamps,but find these very open & spacy! Yet,it may be a better choice in a mixer such as this.
So,I would be grateful for any/all help & suggestions from you experts out there,specially those who have already done these mods on this mixer & your experience in regard to this.
Thanks & greetings.
