Yamaha receiver/amp B370D with speakers making high pitch hum/noise

Hi,
just got Yamaha b370d receiver/amp with speakers. Theres a high pitch noise/hum audible from speakers regardless of volume level. Its audible from close to over 1m distance from speakers. When volume is muted - the hum/noise is gone. Switched all inputs - its the same. Switched different power sockets - the same.
I recorded 3 videos, you can hear the high pitched hum/noise on volume up, gone when muted.
Anyone had similar problem? Should this be returned to RMA?
