Shure PGX24/SM58 Wireless Microphone System Review


There comes a time for many bands or DJs when they decide that their set-up would be better off without wires and they are willing to pony up for a wireless system. Unfortunately, often times they start out with entry-level equipment that just does not get the mail delivered. Surely you have run into this before, or seen it in This is Spinal Tap: radio interference, cutting out, and intermittent bursts of shrieking and static.

That is why I spent a little extra time researching and trying different systems before I ended up getting the Shure PGX24/SM58 wireless handheld microphone system. This system includes a PGX4 receiver and a PGX2/SM58 microphone/transmitter. This is delivered in a nice plastic case that looks like it should have a gun in it.

The PGX4 diversity receiver is a nice looking unit, with two ¼ wave antennae and an LED channel indicator display on the front, and ¼-inch and XLR connector output terminals on the back. This assembly is capable of receiving signals from 90 selectable frequencies across 18MHz bandwidth which provides plenty of opportunities to find some clear radio waves to use.

The PGX2/SM58 is bigger than a conventional SM58 microphone, and this is no surprise as the batteries and the transmitter have to go somewhere. It has a mute switch as well as a multi-function LED that lets the user know if the mute is ON, the power is ON, the power is low, or if the mute is locked out. The lock out feature is handy if you want to keep the user from accidentally turning off the microphone. Just press and hold the switch for 10 seconds while the power is on and it will lock the switch out.

System set-up is easy: I just plugged in in, connected a cable from the XLR output to my mixer (just like a regular microphone) and turned it on. I installed two AA batteries in the transmitter (they are supposed to last 8 hours) and turned it ON. Before putting the battery cover back on I pointed the transmitter at the receiver, pressed the SYNC button and that was it. The automatic transmitter set-up and automatic frequency selection paired the system lickety-split and it was ready to use with no hassles.

The sound performance of the microphone is identical to my conventional wired SM58 microphones. I have not had any wireless problems, such as static or cutting out, and there has not really been any downside to using this system. Of course I install new batteries before each use, so I have not had any problems with battery failure. I find that Shure’s claim of 8 hours of battery life is maybe a bit conservative; I had a set go for 10 hours with no difficulty.

I would have a hard time with letting some drunken karaoke performer loose with one of these, though as they do not come cheaply. The list price for a complete Shure PGX24/SM58 system is $558, and the street price is $399. So, you might be tempted to shop around and buy a dirt-cheap one from a shady seller, but be very careful when buying Shure wireless systems online or from Craigslist ads, as they are now being counterfeited like there is no tomorrow. I have seen a few of these systems being offered on eBay from foreign sellers for half the price without OEM packaging. Caveat emptor, amigos…
