Weird sound when starting up

Anyone have this symptom?

At startup, there is a continuous noise-like sound.

Around February 2022, the manufacturer replaced the electronic board and the frequency decreased.

Also, it’s gotten worse recently, and this sound comes out even after restarting 5 times, and the frequency is increasing.

While this noise is coming out, you can make guitar sounds, but you can’t do anything until it stops.
I also emailed the manufacturer.

Isolation power transformer → QC
Isolation power transformer → TASCAM power distributor → QC

This noise will appear even in studios where these devices are not connected.
I don’t think it’s a problem with the power supply.

I’m raising symptoms on YouTube’s limited release

Translated from Japanese to English.

Same here, got it repaired 1 week ago. Hope the strange noise is not coming back again :roll_eyes:


Please contact the Support Team. I had been having exactly the same problem. I sent the unit to Support yesterday actually.


Echoing Jake, your best bet is to send an email about this issue to They will be able to guide you through the process of repairing or returning it.
