Shure 520DX manual LOW Impedance, Specifications

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 Applica- tions Group at (847) 866-2525 for more information.
