Dual Ring Modulator A-114 on lfo question

2014-10-10 by Dennis Verschoor

Hello.

Does the A-114 works well on slow lfo singals?

Or are there caps which need to be bypassed for this purpose?

Cheers,

Dennis

I just tested for you... It does not respond very well to slow voltages for what I could hear in a quick 3 min. test...

Thanks for the test.

My guess is that there are cappacitors on the inputs filtering dc.

But maybe Dieter can tell about it.

The A-133 is a DC coupled multiplier, works as a ring modulator for  
audio and is really quite a handy utility module in general. In  
modulation terms it can be thought of as an inverting attenuator with  
CV control. It will substitute for a VCA, though where zeroing isn't  
important.

Search for Navs modular blog A-133 for a full article on it.

No, the A-114 works only down to about 50Hz. You may replace the capacitors.
But this will only reduce the lowest frequency. You will nevery obtain DC
coupling. But the A-133 can probably do the job. It is DC coupled.

And adding to Dieter's comments: I managed to get the same sound from my A133 as I got from my A114. Totally possible with the right settings.
