people say it is not clean
...they obviously have not used phonic am220 mixer then ;)
A fine mixer, I use 2 of these for audio singals. No problems. If it only had 5th input...
I bought this item to use as a mixer for my Doepfer modules, I own 3 more modules and in order to be able to send only one output from my 3 modules I found out this mixer. I was not able to find any disadvantage for this item, the knobs have a good sensitivity, both inputs and outputs work just fine, and it is possible to connect this mixer to the main power suply.
For a low number of outputs, as the ones I have this is a great choice for these systems, for biger systems maybe other options should be considered.
So, all in all, I definitely recomend this item to incorporate in a Doepfer based system
Does its job!
Very useful 4 into 1 mixer. I've used it to mix VCO waves into the Wasp filter and the A-116 wave processor.
Will be used a LOT.
Doepfer A-138b
A great little 4 channel mixer that serves it's purpose well. Perfect for summing different elements together. I often use it for mixing dry and effected versions of the same source signal before outputting somewhere else. For the price it is great value and has a fairly smooth sound.
