SP2500 high pitch whine coming from control unit

Recommended Posts

Hello,

 

I got my SP2500 speakers around a month ago. The speakers work and the sound quality is alright.

 

However, the control unit emits very noticeable high pitch whine (coil whine?).

 

It's easily audible and is very annoying. I don't think this is acceptable for a high quality speaker system - kinda ruins the joy of listening.

 

I have made a video demonstrating the issue.

The sound becomes audible once the device is on and seems to be louder when some of the controls are used. For example, turning the volume knob. The speakers where muted just before turning the device off, so after turning speaker system on, the sound is coming from the control unit and the speakers remain muted.

 

The phone next to it is just for visual representation. It's running decibel app which displays DBs and the frequency of loudest noise. It's not the most accurate measurement, but still - an additional data source.

RMA request is throwing the following error as I try to register.

System returned error: System.DmlException: Upsert failed. First exception on row 0; first error: INACTIVE_OWNER_OR_USER, operation performed with inactive user: []

 

Please advise how to proceed.

The portal should be back up and running now Bracka. Create a RMA with part number CA-8910002 and we'll replace the remote for you so you don't have to mail in the entire unit. Let me know your case number when you have done so.

The portal is working once again. I have created a ticket with number 6034096.
