Maximum power consumption / dynamic power

[layer9]

Hi all,

does anybody know the max power the WiiM Amp power supply is able to provide? I could not find any info on it.

Also, does anybody know the maximum dynamic power it can handle? I only found the info regarding the 60/120W constant power it delivers.

It seems the TI3255 can deliver up to 315W at 4 ohms:

Thanks

The WiiM Amp doesn’t have an external power supply. I guess omit one had a smart socket or plug and could monitor power usage you could figure it out.

But there’s no way it’s going to do 315w

Well, not finished. Yet. But let's start with some facts. The Amp seems to be a class D BTL H-bridge amp with a single power rail (find someone smarter than me for an explanation), and with an advanced temperature monitoring through some sensors to deliver "optimal performance and safety" which...

A new unit is with me. Because new device is too cold to be powered, I can focus on external differences. Both units are almost undistinguishable. One difference is reversed channels on RCA inputs. Second one is a class II power supply mark printed on the bottom. I've seen units with reversed...

Most devices I own have a metal plate somewhere on them stating their max power requirement.

It's weird WiiM doesn't
