Analog is a passive DI type not need phantom power or 48V to power, it just works.
This model is DI rack.
4 inputs in total.
for each input there are two balanced mic level outputs, an unbalanced output link.
The connector is for output XLR mic level and Jack input and output link
The configuration could not be simpler.
I do not think there is need for a manual. Or else it is that you clearly need training in sound.
I am not a professional, but I do not notice any difference in sound with Radial or with BSS, I find that there is a different level of output relative to the BSS, it is a little more low, but in general I have seen too many output level when I'm on stage and I have to lower the gain level on the edge of the heavily console, it does not bother me.
The sound is reproduced, it is not altered, it does a very good taf.
I use it for 2 or 3 years now, I remember. I am really satisfied when there is a synth and bass on stage, it looks good service and it avoids walking with plenty of DI.
I've worked with BSS and Radial, I think the PAN 03 does the job as well.
I like the fact that DI is rackable, it's clean, no DI that ride, I put it in the nearest rack and musicians is good. What is annoying is that the outputs bis micro level are at the back of the DI, it's annoying to wire it. Otherwise, it is very thin and small and hides well on stage too. It is really convenient at this level!
I do not know if I would do this choice. I find the quality / price very good opportunity report, in any case I am satisfied.
