The Shure SLXD3+ Plug-On Digital Wireless Transmitter gives professional audio users an easy way to turn an XLR microphone into a wireless microphone. Designed for the Shure SLX-D+ wireless platform, the SLXD3+ combines 24-bit digital audio, dependable RF performance, and flexible microphone compatibility in a compact plug-on transmitter.
The SLXD3+ works with both dynamic and condenser microphones and provides selectable phantom power for microphones that require external power. This makes it especially useful for broadcast interviews, ENG, filmmaking, documentary production, location sound, live events, and other applications where using a cable isn't practical.
If you already own high-quality XLR microphones, the SLXD3+ allows you to continue using them while adding the convenience and mobility of a professional digital wireless system.
Turn Your Existing XLR Microphone into a Wireless Microphone
One of the biggest advantages of the SLXD3+ is its flexibility. Instead of replacing your existing microphones with dedicated wireless models, simply connect a compatible XLR microphone directly to the transmitter.
The SLXD3+ can be used with:
-
Dynamic handheld microphones
-
Condenser microphones
-
Shotgun microphones
-
Interview microphones
-
Boom microphones
-
Professional broadcast microphones
This makes the transmitter particularly useful for production crews that already have a collection of professional XLR microphones.
Phantom Power for Condenser Microphones
The SLXD3+ includes selectable phantom power from +12V to +48V, allowing compatible condenser microphones to operate wirelessly without requiring a separate power source.
This is especially useful for location sound and video production where shotgun and other condenser microphones are commonly used.
With phantom power available directly from the transmitter, production crews can use a much wider range of microphones while maintaining a clean, cable-free setup.
Secure Locking XLR Connection
A secure connection is critical when a microphone is being used in the field. The SLXD3+ features Shure's locking XLR connection to help keep the microphone firmly attached during use.
The locking design helps reduce the possibility of accidental disconnection while the microphone is being handled, mounted on a boom, or used during a live production.
Professional SLX-D+ Digital Wireless Performance
The SLXD3+ is part of Shure's SLX-D+ digital wireless platform and provides transparent 24-bit digital audio with more than 118 dB of dynamic range.
Its 138 MHz tuning bandwidth provides operating flexibility, while advanced RF technology helps maintain reliable wireless performance in demanding environments.
A single SLX-D+ system can support:
-
Up to 11 simultaneous systems in 6 MHz TV bands
-
Up to 14 simultaneous systems in 8 MHz TV bands
Actual system capacity depends on the available frequency spectrum and local RF conditions.
ShowLink® Ease Remote Management
ShowLink® Ease technology provides convenient remote management of compatible SLX-D+ wireless equipment.
Depending on the system configuration, users can manage functions such as:
-
Frequency adjustments
-
RF power settings
-
Device controls
-
Firmware updates
-
System status
-
Lock and unlock functions
This can be especially helpful for production teams managing multiple wireless channels.
Wireless Workbench® Compatibility
For larger or more complex wireless installations, the SLXD3+ can be managed using Shure's Wireless Workbench® software and compatible mobile tools.
These tools can help audio professionals monitor RF conditions, coordinate frequencies, and manage wireless equipment from a central location.
This makes the SLXD3+ a good fit for production companies, broadcasters, corporate AV teams, and other users managing multiple wireless systems.
AES-256 Encryption
The SLXD3+ supports AES-256 encryption for applications where secure wireless audio transmission is important.
This provides an additional layer of protection for sensitive audio and makes the system suitable for applications such as corporate events, educational facilities, government environments, and professional productions requiring secure communications.
Extended Battery Life
The SLXD3+ is designed for extended production use and provides up to 8 hours of operating time on two AA batteries.
It also supports the optional Shure SB903 rechargeable battery, providing a convenient rechargeable power solution for users who regularly work with the system.
