The Shure SLXD24D/B58 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 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 Beta 58A dynamic capsule. The Beta 58A has a supercardioid pickup pattern that focuses on speech, helping to reduce feedback on loud stages. 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.

• 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.

• 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.

• 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.

Q: 1. Will this system work within a studio setting? Will the signal travel through a block wall?

A: You can use the Shure SLXD24D/SM58 Dual-Channel Digital Wireless Handheld Microphone System in a studio setting if you keep the receiver in the same room as the transmitters and run a longer cable from the receiver output to the inputs on the mixer. The signal will not transmit through cinder block walls.

Q: 2. What Frequency Band is best for karaoke?

Q: 3. I HAD THE BLX2 88 OLD MODEL WITH ANTENNAS,AND 2 SM58A MIC,I LIKE TO ADD ON BLX288/58, ARE THEY CAN BE WORK TOGETHER? THANKS, RICK.

A: Yes, you can use the Shure BLX288/B58 Dual-Channel Wireless Handheld Microphone System with Beta 58A Capsules and your older Shure BLX series wireless microphone system at the same time. It doesn't matter whether the two systems operate on different frequency bands or if they both are on the same band. Since the BLX series system has 123 individual frequencies within the band, up to 12 BLX series systems that operate on the same band can be used at the same time within a 300 foot range without any problems.

Q: 4. I have the Dual-Channel System with H55: 514 to 558 MHz band. I want to get a second unit. Should I buy the same frequency band?

Q: 7. What is the vocal frequency range. Is it good for singing at live performances.

A: Human voice vocal frequency range is from about 75 Hertz to about 1500 Hertz. I am not sure what product you are using, tho any pro audio product would reproduce these frequencies. The difference in sound and build quality between various products is subjective.

Q: 8. Does it come with rack mount hardware?

A: Yes, rack mount hardware is included for the receiver.

Q: 9. Can you use both the microphones at the same time (body pack and handheld)?

A: No, you cannot use both microphones (the bodypack and handheld) at the same time because the Shure SLXD4 receiver that comes with the Shure SLXD124/85 Digital Wireless Combo Microphone System (G58: 470 to 514 MHz) is single channel.
