Input impedance is set to a low value on boot

[Kanichan]

CorOS Version: 4.0.0

Describe your issue:
I always keep the input impedance set to 1MΩ, but occasionally on boot, even though the setting still shows 1MΩ, the input level is clearly lower and the behavior is consistent with a low-impedance state.

Changing the impedance to a different value once and then setting it back to 1MΩ immediately resolves the issue.

A reboot also resolves the issue.

This behavior seems to occur primarily on a cold start, such as the first power-on after the unit has not been used for an extended period of time.

Sounds like you should use your QC more often!
Joking aside, I know this was a bug way back in CorOS 1.3 or 1.4 or something. Not sure, but haven’t had it since then.

@Kanichan , As @Gregory indicated, I too haven’t seen any posts regarding this issue. Please email support@neuraldsp.com so they can log your issue and hopefully provide quick resolution. It might be nothing more than a factory reset needed. And welcome!
