I finally made my way to Shure to check out the new ULX-D mic system. Their new mics with the rechargeable Lithium ion batteries look to be another solid product from Shure.  When I arrived at the booth the“buzz”was all about the newly added ULXD4D dual channel digital receiver and ULXD4Q quad channel digital receiver. The new digital wireless mic system enables 47 systems to now operate in just 6 MHz of spectrum by selecting high density mode. The new receivers are also equipped with integrated Dante digital audio networking, which enables multiple channels of audio to be distributed to a variety of devices over a single Ethernet cable…how’s that for A/V Cool!
