The Yamaha AN1x Synthesizer mailing list

just to chime in ,....i use a pair of marinare lo1176a transformers that  
have an gaped iron core with a rc network ( resistor capacitor network) for  
taming  oscillation in higher frequencies,...and it gives a perceived  compressed  
signal,....i never used it with my an1x but i used it  with my mixer which 
has a 600 ohm  output balanced,.....and it sounded  almost like a nicecompressor 
was on it ,.....i suppose the an1x is 600 ohm  too,......i have several 
xformers to give different changes in  tone,....like vintage UFC, and Jensen 
xformers ,...Jensens have a bigger bottom  ,...

Let's  speak electronics again (sorry...) !
You're right Jimmy: the old amps,  effects and synths had a narrower 
bandwidth than today's gear, not to  mention that the frequency response 
was often far from linear. Examples:  spring reverbs, tube amps ...
A guy has found a simple but probably  efficient way to "analogize" 
(sorry again for this horror!) his V.A.  synth, by wiring _audio*_ 
insulation transformers between the output jacks  and the PCB outputs.
See: _http://www.retrosonhttp://www.retrohtt_ 
(http://www.retrosonik.com/DarkMods.htm) 
Because  of the limited bandwidth of the transformers the harsh high 
frequencies  should be more or less cut down.The non- linearities in the 
frequency  range could cause some subtle resonances by increasing or 
decreasing a bit  some fixed frequencies.
I never tried this mod, but maybe i will...one day:  i have the "big 
brother" of his Red Sound synth, an AN1x and others... If  there is 
enough room left to put an audio transformer somewhere inside,  why not ?
Last but not least: of course if you feel yourself unable to do  this mod 
cleanly, or if you cannot find the right transformers, don't do  that! Or 
ask a friendly electronics hobbyist to do it for you....
Don't  want to have a full mailbox of "Shit, my synth is now out with 
your  fucking idea". First it is not exactly "mine" and now you know the  
risks!!
