Shure GLXD24UK/B87A Overview
Shure Beta 87A Digital Wireless Vocal System Precision-engineered condenser vocal microphone with digital transmission. The precision-engineered Beta 87A condenser vocal microphone has a smooth, tailored response for warm, accurate sound. Its supercardioid polar pattern provides maximum isolation from nearby vocalists or instruments. It combines automatic frequency management with true digital diversity for a rock-solid wireless signal with exceptional digital audio clarity.Call GAK now for product info, advice and the Best Prices - 01273 665400
- What are the characteristics of the Beta 87A? - The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the "boomy" sound often associated with close pick-up. The tailored frequency response with its presence rise, brightens the upper midrange and helps the vocals cut through the mix.
- The tight supercardioid pattern provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. It operates on phantom power.
- What receiver comes with the Beta Digital Wireless Vocal System? - The Beta Digital Wireless Vocal System comes with the Digital Wireless Receiver GLXD4. It combines automatic frequency management with true digital diversity for a rock-solid wireless signal with exceptional digital audio clarity.
- Shure proprietary Lithium-Ion rechargeable batteries provide up to 16 hours of continuous use.
- How does the automatic frequency management work? - The Digital Wireless System feature LINKFREQ, an Automatic Frequency Management, making it easy to rely on seamless, crystal-clear audio.
- The receiver continuously analyses the available frequency spectrum.
- The receiver and transmitter automatically link using the best set of available frequencies.
- If interference occurs, the receiver and transmitter intelligently move together to the best open frequencies, without ANY audio interruption.
- It's that simple. No buttons to push or controls to adjust.
- How many musicians can use this system simultaneously? - Depending on the operation mode, up to 8 compatible systems can be operated in parallel.
- In "Automatic mode" (with LINKFREQ enabled) up to 5 systems can be run in parallel.
- In "Manual mode" (with LINKFREQ disabled) up to 8 systems can be run in parallel.
- Rechargeable battery information - Shure proprietary Lithium-Ion rechargeable batteries provide up to 16 hours of continuous use. Transmitter runtime is 1.5 hours with only 15 minutes of charging, (3.0 h in 30 min. / 6.0 h in 60 min. / 16 h in 3 h)
- Is the system license-free? - Yes, it operates in the 2.4 GHz frequency band and is globally license-free
