Description
The SLXD24D+/B58 handheld wireless system, featuring the dual-channel half-rack SLXD4D+ receiver and two legendary Beta¨ 58A supercardioid dynamic microphones, unlocks a new world of hands-free oversight and management for seasoned volunteers and pro engineers alike. Delivering wireless excellence, wherever required, wide-tuning SLXD+ transmitters and receivers stay in sync courtesy of a dedicated ShowLink¨ Ease control link. Manage interference, scan for new channels and update for clear transmission automatically. Also monitor and configure via a paired mobile device.
Features:
- Transparent 24-bit digital audio quality with over 118 dB dynamic range
- Rock solid RF with 138 MHz wide-tuning range for greater geographical coverage:
- Up to 11 simultaneous systems in 6 MHz TV bands
- Up to 14 simultaneous systems in 8 MHz TV bands
- Automatic Setup Ð once linked, SLX-D+ receivers and transmitters stay connected, despite any RF interference
- With ShowLink¨ Ease, transmitter parameters can be adjusted remotely over the air from the linked receiver, including: Ê
- Changing the transmitter frequency once open frequency is identified
- ÊAdjust power output level
- ÊLock and unlock transmitter controls
- Transmitter firmware updates
- Monitor RF status and control receiver and transmitter parameters with Wireless Workbench desktop software, or remotely with the WWB Mobile app over Wi-Fi or Bluetooth
- Patented Shure Digital Feedback Reducer software is embedded in every SLX-D+ receiver, to automatically reduce unwanted audio feedback, should it ever occur.
- Each SLX-D+ component and system ships with AES-256 Encryption installed, for complete and secure peace of mind
- Up to 8 hours of use from either 2 AA batteries (included) or optional Shure SB903 Li-ion rechargeable batteries and charging accessories
Building upon the widely adopted SLX-D platform of transparent, 24-bit digital audio and rock-solid RF performance, SLX-D+ is engineered to add an expanded 138 MHz wide tuning range (region-dependent), plus patented digital feedback reduction DSP and encryption. SLX-D+
wireless systems maintain stable signals from an expanded frequency range of 138MHz Ð offering compatible channels up to 11 per 6 MHz and 14 per 8 MHz TV bands*.
REMOTE CONTROL AND MONITORING
SLX-D+ features ShowLink¨ Ease, a dedicated control link between receivers and transmitters that enables remote management and powerful automated features.
WIRELESS EXCELLENCE. WHEREVER REQUIRED.
Offering a wide selection of rack-ready and portable system configurations and microphone options, SLX-D+ Wireless Systems are ready for every stage, theater, or house of worship event.
