FW: [Doepfer_a100] A-138D FX insert query
2017-06-28 by Tim Burgess
Hi, Just to report back that I now have glorious stereo reverb via my A-138D units. Thanks for the help guys, and apologies for me pressing the bypass button on my brain. Best wishes. Tim Burgess

I'll try to do it anyway, from far away it's even harder. As far as I know, unbalanced sockets to balanced ones shouldn't be a problem, but if you don't own XLR unbalanced to TS jack cables to try with then it wouldn't be cool to purchase them just for this trial. By the way, if the module is designed to work with pedals and stomp boxes only then a problem of impedance bridging probably might occur, though a signal should be heard anyway. I neither know if the external unit is expected to work as serial (compressor, limiter) or parallel (reverb, delay..), though you're mentioning send/return then the latter should be the case. So, if it is a delay reverb unit, I suggest first to check only sending the signal to the unit, while connecting its outputs into a mixer channel strip, a audio interface input or another available line input, instead of returning the processed signal back to the A-138d. This way you can check if the lack of audible signal was due to a knob to be better tweaked on the Doepfer module. or just a wrong connection on it. You might also check sending a signal from another unit, not the A-138d, in order to see whether there was some inappropriate setting on the send section of the A-138d.

However, the TC unit only provides XLR connections, a left-right pair for input and another left-right pair for output. I have some cables with the appropriate XLR genders at one end and 1/4@" TRS connections at the other. However, when I wire this up, I get nothing back from the effects unit. Unfortunately, I can't validate that signal is getting as far as the effects processor, as I'm blind, so can't look at the unit's meters. I assume that my problem is that the A-138D has unbalanced sockets for the sends and returns, so I'm getting signal cancellation - is this the case, please, or are there other things I might try? I should say that the A-138D units are working fine as cross-faders. Many thanks in advance for any advice. Best wishes.
