Plug in the SNOWSKY TINY A, then pick it in the browser dialog.
The TINY A's PEQ is ten bands at fixed centres — 32, 64, 125, 250, 500 Hz, 1, 2, 4, 8 and 16 kHz. A profile exported from another device can carry other frequencies, and a band that has wandered out of its slot is a filter in the wrong place: the knob shapes the right slot, but that slot does not sound like 32 Hz any more. Restore puts the ten centres back and leaves every gain, Q and type alone.
Pick the slot before pressing Save — saving overwrites whatever is
already stored there. The TINY A has no separate save command, so writing
into the selected USER slot is what stores the curve.
Importing applies a profile immediately — you can also drag an
.xml file straight onto this page.
Transport: WebHID (report ID 7). The TINY A exposes its control interface as HID class, which WebUSB refuses to claim — WebHID is the only browser transport that can talk to it.
