Prezentare Sistem Wireless SHURE -Microfon Vocal GLXD24/B87A
What is the Beta 87A best suited to"
The Shure Beta 87A is a premium quality supercardioid hand-held condenserCondenser microphones are more sensitive, give a smooth, natural sound and need to be powered.Read moreGo to the glossary vocal microphone with exceptionally smooth frequency response and high sound pressure level capability. It is ideal for a professional lead or backing vocalist either on stage, for live recording or in the studio.
What are the characteristics of the Beta 87A"
The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effectWith a directional mic, more bass is added when the mic is closer to the sound source.Read moreGo to the glossary 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.
How is the handling of the rechargeable batteries"
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)
Multiple Rechargeability options:
Charge battery alone:
