JBL EON 510 Input Module Schematic needed
Hi everyone, I got a defect JBL EON 510 speaker ( no sound, but all LED are ok ). It contains 2 modules: input module and amplifier module. I found the schematic for the amplifier and this seems ok. Now it would be very helpful to have the schematic for the input module ( it has several 4580 op-amp ICs ). Thanks

just a suggestion, but check if the EQ switch is good. If the switch is broken inside, the input led will light up that there is signal but no sound will come out.

Fixed it! Shandryderrick you were right, it was the EQ - switch. Bridged the switch in position "FLAT" from pin 1 to pin 3, as I don't need the EQ that often. Jazz P Bass & Shandryderrick, thanks for the excellent support.
