hello,
yes, but Anton meant the a188-2 tapped bbd module.
so, it seems that his problem is not the same as in
your module. Anton probably has a defective unit that
needs repair. (as indicated by Dieter.)
as for your unit, i also have the 4096 bbd module and
have not noticed any wierd behaviour in mine...
but, maybe, all you have to do is filter the clock
noise for this, just insert a steep slope LPF module
before the bbd module's audio input and after the bbd
module's audio output.
best regards,
Bakis.
