Power supply for Shure UA844
« on: March 01, 2020, 02:30:51 pm »

Hi, can anybody advise me on the following, I have purchased a second hand Shure UA844 the problem is that it was supplied with a shure PS40UK power supply, the correct power supply would be a PS45UK or the up to date PS60UK, Shure say that I need either the 45 or 60, but I guessed they would, can anybody tell me if the PS40 will work ok and not cause problems, I know Shure would only advise on the correct item but they are so expensive.
Thank you.

The PS40 is only rated for about 600mA of output. This is probably enough power to run the distro itself, but likely only the distro itself. Active antennas might cause the PS40 to struggle (i.e. overheat and fail); using the power splitter to power RXs would be right out of the question.

UA844 can also power up to 4 receivers. Do you use that function?
