Need help choosing?
Choose the SLXD3+ when you already have an XLR microphone that you want to make wireless, particularly for boom, ENG, interview or location work. It is the right SLX-D+ transmitter when phantom power is required at the microphone. For lavalier or headset use choose the SLXD1+ bodypack, while the SLXD2+ range is the better option for handheld capsules. Make sure the transmitter band matches the receiver band.
The Shure SLXD3+ is a professional wireless plug-on transmitter that converts compatible XLR microphones and line-level sources for use with SLX-D+ digital wireless systems, making it ideal for ENG, boom, interview and location-sound workflows.
A patented locking XLR mechanism keeps the transmitter securely attached, while selectable 12V or 48V phantom power supports compatible condenser and shotgun microphones. SLX-D+ provides transparent 24-bit digital audio, more than 118dB dynamic range, AES-256 encryption and ShowLink Ease remote control from a linked receiver.
