The PMX-USBEXT is a 33 foot (10 meter) extension cable for the USB connector on the rear of select PMX source units. This allows for a convenient access to the USB input to load and play music through your PMX radio over long distances, like in a boat. The maximum length of standard USB 2.0 cables is only 5 meters (16-1/2 feet.) The cable is self-powered (using the USB charging voltage) by utilizing an internal amplifier to extend the transmission length.
