ekadek is actually saving the planet

my want and need for a few days last week was to dissembowel an AUDIMAX  4440A.  ive appreciated  the quality of the line sound sound of these . they are all transistor. no chips. made well. fat sounding. hi class parts.  made expensive for 1980s FM RADIO broadcast mixer insert and transmitter output stages.  but the dynamics of the thing doesnt have much  to offer a modern studio context. the long hardly changing average level adjusting functionality doesnt fit with any useful requirement that i know of. ok. well just maybe… to keep one thing absolutely the same. huh wtf etc. ( wait a minute. isnt that a whole new music genre?) . anywhoo.. this audimax is kind of made to be an  “AVERAGiNATOR” ….  ..good for making overall levels incredibly hi quality average. sounds  like the eighties to me.


so ive ripped out the “MEMORY UNIT” .  this expoxy potted mystery thing contains live electrical memory that judges how ‘loud’ a track is overall and then compares that knowledge with another sensed and evaluated voltage doubled  judgement of whether the newly adjusted overall level is moving upwards .. or downwards.   brilliant…?  it then makes an external  transistor and fet act against eachother to make that prepostperceived judgement into an overalled averaged representation -  as a dc sucking blowing potential that operates on the balanced patented varilosser signal attenuating circuit . averaging the averaged control signal to make everything extremely average.

so  i was saying..  ive ripped this average brain  right out of the picture. (and fully intend to gore out the epoxy, plunging into that waxy juicyness))  and have transplaced it with an awesome workaround to recreate these puppies into very good working almost brick wall limiting amps. they are way more like a punchy solid state compressor now. still more experiments to do tho.

all without wasting all that energy that originally went into their 1980 manufacture.  just another fine example of how ekadek and its minions works so hard to save the planet. so other news is that IGOR is working up a top secret design for extra sensitive single cycle  transient suppression.  he wants to bring every dominating inth that computer functionality has …back  out of the box and into the sunlight… (cue  manic-al laugh)
