My frieend Casey Johnson is a rep for Shure Microphone and he sent me this message about the Shure X2u USB Signal Adapter:

It does have latency, but the headphone amp monitors the mic, before the DSP, therefore, no latency.

The reason I bring this up is someone tried to argue with me that another manufacture has a device that goes analogue to dig with no latency which cant happen... (yet)

Also, I plugged mine in and it just worked. It truly is plug and play. Smaart saw it as a device and used it for an RTA. I'm waiting on 2, one to use for each channel of smart. I'm not sure if it would work or not...

Please let us know what you think.
