Shure SLXD24D/N8C Dual-Channel Digital Wireless Handheld Microphone System with Nexadyne 8/C Cardioid Capsules (J52: 558 to 602 + 614 to 616 MHz)

Shure SLXD24D Overview

The Shure SLXD24D/N8C offers two presenters or performers a dual-channel wireless handheld microphone system that's dependable, easy to set up, and features crystal-clear, digital sound quality. Built around a rugged, dual-channel, single rack receiver with removable antennas, the system is ideally suited for portable rigs or long-term installations in small- to medium-sized venues, event spaces, conference rooms, houses of worship, and education facilities.

The SLX-D operates in the J52: 558 to 602 + 614 to 616 MHz UHF band to transmit high-quality, 24-bit digital audio with over 120 dB of dynamic range for crisp, detailed sound. It utilizes Digital Predictive Switching Diversity to protect the transmission from interference and deliver a solid, reliable RF signal without dropouts.

This configuration includes two SLXD2 handheld transmitters, each featuring an interchangeable microphone capsule design and equipped with a Nexadyne 8/C dynamic cardioid capsule, featuring an innovative Revonic dual-transducer design that uses two separate, but interdependent sets of diaphragms, voice coils, and magnets. This unique technology gives this dynamic mic a condenser-like clarity with a crisp, yet natural high-end and plenty of detail, allowing vocalists to worry less about mic technique and instead focus on delivering powerful performances. The cardioid polar pattern reduces off-axis pick up, for less bleed from other sources and fewer feedback issues.

The lightweight metal transmitters feature a selectable 1/10mW RF power output and a transmission range up to 330'. Power is supplied by two AA batteries or an SB903 rechargeable battery (available separately) for up to 8 hours.

The all-metal, rackmount SLXD4D receiver features an intuitive LCD interface with meters for RF, battery status, and audio outputs. It also offers 60 dB of gain control, and both mic/line XLR and 1/4" instrument outputs for each channel. Additional features include automatic frequency scanning and IR sync to easily link the transmitter and receiver to the same frequency.

With up to 32 mic channels available at the same time, the SLX-D is ready to expand as your needs grow. What’s more, setting up multiple systems is made fast and easy via the Ethernet port, which links them together for quick, coordinated frequency scans from a single receiver.

Two Handheld Transmitters with Nexadyne 8/C Cardioid Revonic Capsules

• With durable aluminum housing, the SLXD2 handheld transmitter offers a lightweight design that's comfortable to hold and features an LCD to show essential information.
• The 8/C mic capsule in this version of the transmitter features Shure's Nexadyne Revonic system, an innovative dynamic microphone design that uses two matched dynamic transducers, working in conjunction, to provide more opportunity for both greater sound quality and the rejection of unwanted signal.
• Wiring the transducers out-of-phase cancels mechanical vibration, so self-noise is actively zeroed out. This makes traditional pneumatic shockmounts unnecessary, and allows the transducers to be optimized for acoustic performance.
• Vocal performers will experience natural and vivid clarity when performing—enabled by a cartridge design that optimizes signal output acoustically, producing more of the desired sound source and less environmental and handling noise.
• Engineers will receive stronger and clearer output, resulting in fewer EQ corrections that are often necessary with other mics to retain vocal clarity within the mix.
• The cardioid polar pattern provides focused, yet forgiving, audio capture centered on the performer in front of the mic—reducing bleed from other sources and on-stage monitors for clearer sound.
• The transmitter's interchangeable capsule design allows you to choose the ideal capsule for your application. Shure offers a variety of optional dynamic and condenser mic capsules with varying pickup patterns—capsules include the Nexadyne 8/S (supercardioid), Beta 87A, SM58, and KSM8.

Transparent Digital Sound, Dependable Performance, and More Mics

• The SLX-D delivers 24-bit digital audio with a fast transient response and over 120 dB of dynamic range—resulting in clear, accurate sound for your events.
• The system operates in the J52: 558 to 602 + 614 to 616 MHz UHF band with a 46 MHz tuning range and 1840 selectable frequencies, far away from potential Wi-Fi interference in the 2.4 GHz band.
• Digital Predictive Switching Diversity uses a microprocessor to switch between the two antennas for the cleanest signal—before dropouts occur.
• With a low latency of 3.2 ms, the system is ideal for applications that require live sound reinforcement.
• The SLX-D's spectrum-efficient digital transmission technology allows for up to 32 mics to be used at once.
• Up to 10 compatible systems per 6 MHz TV band and 12 systems per 8 MHz band are supported.
• Ethernet networking saves you time with coordinated group scanning between multiple receivers from a single location; TCPI command streams from third-party companies such as AMX and Crestron are also supported.

Ready to Rackmount, Easy to Use

• Housed in a tough, single-rack metal chassis with detachable antennas, the SLXD4D dual-channel receiver is a great fit for A/V installations or as part of a portable rackmount rig—ready to travel to a meeting or event.
• The SLX-D is engineered to provide outstanding sound for small- to medium-sized spaces and facilities—without costly, complicated features required primarily for large venues.
• Intuitive front-panel controls and a high-contrast LCD screen with audio and RF meters makes set up a snap.
• The auto-scan function automatically seeks out the cleanest available frequency for you. The receiver and transmitters then easily link to the same frequency via infrared.
• The receiver offers up to 60 dB of adjustable gain and the display shows you where the ideal levels should be.

Optional Rechargeable Battery Management

• Adding the SB903 lithium-ion rechargeable battery, along with an SBC10-903 single charger or an SBC203 dual-docking charger, offers a cost-effective and environmentally friendly alternative to throwing away AA batteries (battery and chargers available separately).
• Using the SB903 battery and SBC203 charger simplifies the task of keeping multiple transmitters charged and ready—you can even recharge the battery while still in the transmitter.
• When powered by an SB903 battery, each transmitter displays the remaining run time in hours and minutes.

Enhance the Reliability of Your System

• Adding UA874 active antennas or PA805SWB passive antennas increases the range of your system and offers increased protection against interference.
• The UA844+SWB antenna distribution system (available separately) lets you stretch the power of your antenna pairs, giving you more on-air channels in less setup time.

A Variety of Mics and Transmitters Available

• Shure offers a bodypack transmitter with a variety of lavalier and headset microphones to adapt your system as your needs evolve.
• The WL183 (omnidirectional), WL185 (cardioid), and WL184 (supercardioid) lavalier mics offer hands-free presentation options.
• The miniature WL93 and subminiature MX150 mics are smaller, easy-to-conceal lavaliers.
• The discreet MX153 subminiature earset mic provides exceptional clarity...
