I need some info regarding Master Room XL-305 Reverb, I need the schematics or at least the pin out for the IC ESM532C DIL configuration.

Hi kamskoma -

I designed the XL-305's electronics while at MicMix.

I've posted schematics of the unit here:

It has the ESM532C SIP pinout. I've been unable to find the datasheet. It was made by SGS/Thomson.

john1 at the Pro Audio Design Forum was kind enough to send me a pdf of the ESM532C datasheet. It's posted here:

problem with reverb

Hello mediatechnology,
I was wondering since you designed it if you could help me troubleshoot my unit. The unit turns on but doesn't really pass signal. The LED meters do not show any sort of signal. I have replaced the chips, voltage regulators, and the filter caps recently. Could it be that ecm chip? I can only find them on ebay and am scared to spend so much on two new ones if they are fine? Any tests I should try? Any help is greatly appreciated. Thanks
