EML 200 electronic switch

EML 200 electronic switch

2015-03-20 by klosmon@...

Hello-
I've just acquired a 200 -- trying to understand the switch function.
From what little is in the manual, and looking at the front panel, it would seem that the two "on time" controls should function similarly;  on this unit, the B control seems to affect the switching speed, while the A control is switching waveshape.
Does this indicate malfunction of the module, or  do they all work that way?
Thanks.

i don't think they interact with each other. each one is a separate timer according to the manual.

If you put two different VCO tones in each input. The gain control is basically the level control for each channel.

Center both A and B “On Time” pots and it will switch between the two channels equally.

But, the period of time a channel stays “on” gets shorter as you turn the “On Time” control CW and longer CCW.

Basically, it just bounces back and forth between the two sources at whatever time setting you set per channel.

 

If you apply a patch cord to the pulse input on Channel B, it will remain on channel B until a pulse/Gate is applied and it will switch to the A channel for the A On Time amount then, return to the B channel until the next pulse is applied.

OK, thanks. That would indicate there's definitely something wrong with
this unit.
Will dig out the schematics & scope this weekend to try to track down
the fault.
