Shure AD4D-DC

The AD4D-DC is the two-channel Axient Digital receiver for shows that cannot afford a dead RF link. It puts two independent receiver channels in a single rack and combines two discrete RF signals per channel with Shure's quality-based ratio-combining algorithm to fight multipath, fading, and dropouts. Wide UHF tuning fits a large channel count into tight spectrum, and 2 ms latency with 256-bit encryption keeps the audio tight and secure in dense RF environments.

The DC in the name is a redundant DC power input: a locking DC connector lets a battery or DC supply back up the mains so the receiver stays up if AC fails. It ships tuned to one band - A (470-636 MHz), B (606-810 MHz), or C (750-960 MHz) - and outputs analog XLR plus AES3 digital with Dante and AES67 networking. In the box are the dual-channel receiver, locking power and jumper cables, a BNC bulkhead adapter, coaxial antenna, BNC cable assemblies, a BNC cable, Ethernet cables, a rackmount kit, and the user guide.
