LOW IMPEDANCE

To connect the 520DX to a low impedance device, such as a
mixer, use a low-to-high impedance-matching line transformer,
such as the Shure model A95U.
NOTE: The 520DX can be rewired for low impedance, but this
disables the volume control. Contact the Shure Applications
Group at (847) 600-8440 for more information.
