Topic: RME Fireface 800 hiss

Hi guys!

I've just purchased a used Fireface 800 unit. I've been using Fireface 400 up until this point.

When I turn the device on without any cables I can hear a quiet extremely high pitched tinnitus-like hiss coming from the area where the power supply is on the device itself.

But when I actually use the device, when music is played, or when the ASIO drivers are in use by a DAW, this hiss becomes very loud. The hiss changes with the sample rate.

I'm using a firewire PCIe card to connect to my ASRock Fatality MB.

I'm guessing this hiss is normal for an old device and is due to the old capacitors?

Thank you!

I never heard this, but power supplies needing replacement on an old Fireface 800 is nothing unusual.
