OUR PART # ULXD2/K8B-J50
The Shure ULXD2/K8B-J50 is a handheld transmitter with a KSM8 Dualdyne dynamic cardioid cartridge that is designed for use with Shure's ULX-D wireless systems. This handheld transmitter operates in the J50 band (572 - 636 MHz).
The KSM8 cartridge was painstakingly crafted for the highest possible audio quality for live sound applications, and thanks to its Dualdyne dual-diaphragm design, it has the purest cardioid polar pattern available in a Shure product. This means that the off-axis rejection is incredibly smooth – even in high volume environments – so feedback is much less of a concern. Plus, the Dualdyne cartridge all but eliminates proximity effect, so there's no need to worry about artificially boosted low-end frequency content.
The Dualdyne cartridge features both active and passive diaphragms. The passive diaphragm is part of the cartridge's acoustic network to provide for the virtual elimination of proximity effect as mentioned above, as well as low-frequency handling noise. The patent pending Diaphragm Stabilization System (DSS) Technology protects and stabilizes the active diaphragm from unwanted excursion or rocking during plosives or impact to provide outstanding protection against high-frequency handling noise. This means that the Dualdyne cartridge is working twice as hard to provide the most accurate and neutral sound possible.
