If that is the case, then I am going to start up a way to give all those dust collectors out there a home; in my studio! With a bit of study, you should be able to figure out which is what. Regarding the jumpers to cut to disable the gate, I found the old thread showing it and attached the pic: Have Schematjc actually solved the oscillation problem? The ‘s meters both channels and the sound board’s meters never completely shut off until I unplugged the long cable run from the compressor, and I could sometimes hear a xlesis drone in addition to the intended sound.


I am a video producer.

If the alesis already uses them sorry for the verbal garbage, but they probably have some cheap electros that will make the compression sound The SPDT switch should be wired across the jumper cut in the TapeOp “Two-Snip mod” so the gate will be removed from the compressor circuit when this pot is turned off.

Also regarding the gate, does anyone have a reference or picture of the TapeOp “Two-Snip mod” that tells which jumpers you cut to disable the gate where to install the SPDT across?

It might be a pain in the ass to desolder them. Maybe they still do. Avoiding Oscillation Ask Question. Regarding the VCA mods, I have a note in one of my messages that says: First attempt oscillates, but is somewhat useable anyway. So can someone tell me what it is that I should be hearing through a that makes them so bad?

Would it not then be better to replace them, for example, with something like WIMA polypropylene? This would produce a line-level, isolated output at the receiving end.

It was in my searching for one that I discovered this forum. Obviously, many folks have tried them out since opinions run rampant and have replaced them with schemaic of quality.

Hey Cool about modding the alesis Better is always better, but don’t expect a night and day change. August 07, AaronD 4, 5 The time now is Sign up using Facebook.

They look like ceramics http: The has been the butt of jokes here for literally years. That jumper thread also mentioned another mod from smallbutfine I’m curious about: But they’ve got the values printed on them so that should be doable. Page 1 of 3 1 2 3 Last Jump to page: Present any other potential problems? Stop the oscillation Make both ends identical Incorporate the compressors directly into the driver circuitry to have one less bulky box So, I’m thinking about using a THAT “Analog Engine”which includes a VCA, a true-RMS envelope follower, and a couple of opamps, to drive T1 from this app note.
