Hello Daniel, how much current 7055-C drains when in use in USB 2.0 mode: 0.4 A? Is its minimum working voltage 4.5 V (I saw both data on the specs sheet)? This means that, without aux power supply, the next part of the USB chain, at far end, "sees", in worst case, 4.5 V minus next cable v...

Hello Daniel, thanks for the reply,

I've just filled a RMA form for the unit, but at this point you can ignore it.
I'm sorry I was feeling a bit apprehensive about the "issue".

Cheers,

Hello, I try to bring UP the topic :) To summarize, I suspect that MY 7055-C isolator doesn't work. As tested, it seems that is not providing galvanic isolation. The "tingle" on MacBook chassis, when charging with two prongs charger, is not there, as if the ground of the laptop and the DAC...

Hello, I'm experimenting different isolation behaviour between 7055-C and 7054 (standard version). The scenario: MacBook Air battery powered or connected to power supply (not earthed power supply) --> USB-2 cable --> 7055-C or 7054 (standard version) --> RME ADI 2 DAC FS --> amplifier --> loudspeake...

Hello,

is there a plan to a future isolator version with USB-C connectors?

Stefano

Thanks Daniel,

Hello,
any USB cable length with Intona 7054 is possible within USB 2.0 max of 5 meters?
Or is there a suggested max cable lenght from host to Intona and from Intona to device in order to minimize interferences and voltage droop?
Thanks and Regards
Stefano
