Hi,
I have noticed a constant whistling tone in my speakers at around 4300Hz when using my SHD regardless of input source. I have previously used an active speaker in the top (HEDD05) but not noticed this tone before. My new speakers are passive and driven by a NuPrime ST-9 connected to the SHD with XLR cables.
Would welcome any ideas about how to solve this.
Best,
/Stefan

That's pretty weird. If it were me I'd identify whether it happens regardless of input, and whether volume changes anything. If it happens even with nothing is connected to the SHD inputs and it doesn't happen when the SHD is disconnected from the NuPrime then perhaps take an RTA of it and open a support ticket?

Partially solved by using RCA cables instead of XLR! A bit strange since balanced cables should be more resistant to noise and hum. It is only my ribbon tweeters that pick up the tone (4300 Hz). My AMTs do not. Well, good enough for me anyway.
