PGX14 Wireless Guitar System

The Shure PGX 14 Guitar Wireless system offers superior wireless technology and automatic set-up features. The system comprises of a PGX1 bodypack transmitter with a WA302 instrument cable and a PGX4 Diversity receiver.

Fast and easy setup, even for a beginner

Simply press the channel button on the front of the receiver and it will perform a quick scan of the area and select a clear frequency to avoid any unwanted interference. Once this is done, sync up the receiver with your transmitter by pressing the sync button on the receiver and pointing the infrared port on the transmitter at the receiver.

How many musicians can use this system simultaneously?

A maximum of 8 musicians can use PGX Wireless systems in parallel. One wireless system consists of one bodypack transmitter and one receiver.

I normally plug my guitar straight in to my amp. Will the wireless affect the sound?

The PGX system uses Shure’s patented Audio Reference Companding which makes the system sound just like a wired setup. With less noise and greater dynamic range than other wireless systems. No artifacts lower noise floor and clearer sound at all levels.
