Above all, I note that I am the manufacturer, but also the first user of my products, so here I give an opinion as objective as possible, I do not talk about price ... and give an average rating each item, not to skew the average rating future.
Technology used: Passive transformer OEP.
Connectors: Jack in asymmetrical between symmetrical XLR output.
Switch Ground / Lift. Note that the output in both floating mass, this switch might not be presents, but as most IDPs have one, I put it (even when it is active!)
No power ncessaire, it is even advisable to disable the phantom power from the console. If you can not, then it is better to switch the ground / lift position "lift"
We can not be simpler, 1 input, 1 output, no rglage is small, it is practical and does exactly what the functions of DI.
Regarding the sound, despite a bandwidth and a Frequency Response collgue its close enough, the DI-L, the sound does a little less convincing in terms of musicality. C'tait mtallique a little more, without being dsagrable.
In practice, it is better on bass or guitar on a keyboard.
In the end, I found myself on stage dj plug my keyboards on DI BSS, Samson, Behringer ... and globally (which does not mean all the time) or I saturate the DI or I had problem of the masses ...
When I take this DI, I know it will work without problem, made a less worries on stage.
