SLXD3 Plug-On Digital Wireless Transmitter converts any XLR source, including dynamic and condenser microphones, for use as an SLX-D wireless transmitter. Featuring a patented locking ring for a secure, wobble-free connection, the SLXD3 sends 24-bit digital audio from any XLR source to an SLXD4 or SLXD5 Digital Wireless receiver via a rock-solid RF connection. Use IR Sync to pair transmitters easily and quickly with your choice of SLX-D wireless receiver. A full suite of optional rechargeability accessories enables wireless excellence, wherever required, and the bright OLED screen displays battery life in hours and minutes when used with the optional SB903 Rechargeable Lithium-Ion batteries. Includes SLXD3 plug-on transmitter, a pair of AA alkaline batteries and a leather protective sleeve with an integrated belt clip.
