Significant mods for the DOD R-825 Compressor/Limiter
In reference to the post quoted under I wish make a previously mentioned topic resurface, for the benefit of anyone who wishes to sprite up their mono compressor;
Now, I wonder which one is the 5532 opamp, as I cannot read that number anywhere on the layout.
Also, I would like to call on you for your suggestions for a replacement opamp.
As you can see the quoted poster suggests thithe AD826 (is this the one?)
Why would the AD826 make the R-825 better on vocals?
And what do the terms opamp bandwidth and speed mean - What are the effects of variations in these?
An lastly, is this an easy mod? Is the opamp socket the same?
All your replies are greatly appreciated
best regards

You can see the schematics hereDaniel Gomez said:The DOD R-825 absolutely features the dbx 2150A VCA chip. In fact it has two. One on the regular compressor circuit and one in the de-esser section. I just opened mine up last night to check on it as I am a "modder". Everthing is in sockets so another great replacement would be to upgrade the 5532 opamps to AD826, a much faster (slew rate) and wider bandwith device. I will be selling mine, is any body interested? I used it on Bass alot as it was pretty transparent. Not a bade compressor but not very good for vocals although the Mod would help with that. I need to cull some stuff I don't use any more from the racks. Good luck.
