AKG WMS470 Presenter Set BD7 - 500 to 530.5MHz Analog Wireless Microphone System with SR470 Receiver/PT470 Bodypack Transmitter and C555 L Headset/CK99 L Lavalier Microphones in Black Finish

The AKG WMS470 Presenter Set BD7 is a high-performance wireless microphone system designed for professional sound reinforcement in a variety of applications, including presentations, seminars, house of worship, and other live events. Featuring the SR470 receiver and PT470 bodypack transmitter, this versatile system offers flexible operation with a 30 MHz tuning range, allowing up to 1200 selectable frequencies for multiple channels to operate simultaneously. With the ability to use up to 20 channels in a single frequency band and up to 48 channels across multiple bands, this system is ideal for complex multi-channel environments.

The SR470 receiver, which is housed in a half 19-inch all-metal case, utilizes a uC-controlled space diversity system to enhance signal reliability and reduce dropouts. The receiver's frequency selection is automatic, with up to 16 pre-programmed frequencies within the same frequency band. It also features an infrared link for easy frequency and setup data transfer to the transmitter. The receiver's front panel includes a clear LCD display showing the selected channel, along with an RF OK LED for signal status and a CLIP LED to indicate excessive audio levels. The two-color display backlighting is designed to indicate critical operation conditions, such as low battery, audio peaks, or low RF signal.

For seamless operation, the SR470 provides both balanced XLR outputs (with selectable -30 dB or 0 dB output levels) and unbalanced 1/4" TS jack outputs, offering flexibility for various audio setups. The receiver also supports the use of external directional and omni-directional antennas to further extend signal coverage, particularly in multi-channel configurations, and includes 2x 50-ohm BNC female connectors for antenna inputs. With a frequency range of 500.1 to 530.5 MHz (Band 7), the SR470 provides crystal-clear audio transmission for a wide variety of professional uses. The receiver operates on a 12V DC power supply and can be easily integrated into any professional sound system.

The PT470 bodypack transmitter is designed for flexibility and ease of use. It connects to the included C555 L head-worn microphone or the CK99 L lavalier microphone, both of which offer exceptional sound quality. The PT470 is powered by a single AA battery, providing up to 14 hours of continuous operation, ensuring reliability throughout long events. The bodypack transmitter features a TB3M 3-pin mini-XLR input, making it compatible with a variety of AKG microphones. It also includes an adjustable gain control and a noiseless On/Off/Mute switch, making it easy to manage audio levels and microphone operation discreetly. The transmitter is lightweight and comes with a BC400 belt clip, allowing for comfortable, hands-free use during presentations or performances.

The included C555 L head-worn microphone is a pre-polarized condenser microphone with a cardioid polar pattern, ideal for capturing clear, focused sound in active environments. With a wide frequency response of 80 Hz to 20 kHz and high sensitivity (25 mV/Pa), the C555 L ensures exceptional sound quality even in challenging conditions. It also includes a W444 windscreen to reduce noise from wind or breath. The CK99 L lavalier microphone, which is also included in this set, is a small, lightweight microphone with a cardioid pattern and excellent noise rejection, making it perfect for hands-free presentations. Its sensitivity of 8.8 mV/Pa and signal-to-noise ratio of 60 dB-A ensures clear and accurate sound capture for professional use.

This comprehensive system offers superior audio quality, flexibility, and reliability, making it ideal for presenters, performers, and audio engineers who require a high-performance wireless microphone system for a variety of applications. Whether you're hosting a seminar, delivering a lecture, or performing live, the AKG WMS470 Presenter Set BD7 provides a cost-effective, professional solution that delivers exceptional performance every time.
