[sdiy] Anyone try the Cool Audio chips?

[Ģirts Ozoliņš]

We use V2164 in our Erica Synths Quad VCA, and with preemphasis – deemphasis circuits they work exceptionally well!

Also, we use 1024 and 4098 stage DDBs in our Erica Fusion Delay/Flanger/Vintage Ensemble, and I’m really happy about result – no audiable difference form MN ones.

 

Have fun!

Cool Audio V2164 is a staple of many designs and manufacturers.  I have some of their other cloney chips, but haven't actually gotten around to trying to apply them (e.g. the BBDs, the companders).  The BBDs are definitely low-voltage versions though, the data sheet for the V3205 says 5V operation.....  So you lose headroom....

Wondering if anyone has been using the coolaudio parts in their builds?


I've used a pair of the CoolAudio v3205d chips in a Memory Man clone a couple years ago. Very noisy, compared to vintage MN3005 or modern XVIVE3005 reproductions. (This could be partly due to a 9v vs 15v difference.)

For MN3207 duties, I prefer BeiLing reproductions if vintage chips are not available.
