You sure about powering your Shure Wireless System?

A wireless mic system – well, it has to be good, doesn’t it? If there’s interference or or drop outs – it just won’t cut it.
Shure makes some of the most reliable wireless mic systems, and they know their gear; they’ve been around since 1925, when Sidney N. Shure founded The Shure Radio Company in downtown Chicago, Illinois. In 1953 they unveiled the “Vagabond” – the first wireless microphone system for performers, it made you “foot loose and fancy free”, although Frank Sinatra allegedly threw one against a wall, he became so enraged by the poor range of it. Shure improved its offering and is still going strong close to 100 years on, innovating and making great gear to this day.

But what do you need to power your Shure wireless mic receiver when the power adaptor takes a long walk? I get asked about this a lot so I thought I’d clear it up right now.

So here’s the rear of a popular Shure wireless receiver, the BLX4. You can see the power input on the left: it says “12V to 15V”:

Here’s another – the read of the the Shure PGX4 – it states “12V – 18V”:

If we look close up we can see the full spec of the power adaptor. It takes 12V to 18V DC inclusive, and requires centre positive polarity. It also uses maximum 160mA of current, so you need a PSU that delivers at least 160mA of current.

So 12V is perfect for it – it doesn’t need any higher voltage than that. Although you can use up to 18V and it’ll be fine too.

You can get exactly the 12V mains power adaptor you need here from myVolts: Shure PS21UK – use code CSPOW for 2 GBP off.

And, in case you haven’t heard, myVolts also makes its unique 5V to 12V USB power adaptor, so you can power your Shure wireless receiver from any USB port: Shure USB power adaptor.
