AKG WMS470 INSTRUMENT SET BD7 - Professional Wireless Microphone System

AKG WMS470 Instrument Set BD7 Professional Wireless Microphone System

The AKG WMS470 is a professional-grade wireless system engineered for touring musicians and studio professionals who demand reliability without sonic compromise. This body-pack transmitter system delivers consistent wireless performance across stage or studio environments, letting you move freely while maintaining the natural tone and detail of your instrument. Built on AKG's reputation for legendary engineering, the WMS470 has proven itself as a workhorse on countless tours and sessions worldwide.

Audio Performance & Wireless Architecture

The SR470 receiver operates on a wideband FM modulation platform with a microprocessor-controlled diversity circuit, delivering a signal-to-noise ratio of 120 dB(A) and THD below 0.3% for transparent audio reproduction. Audio bandwidth spans 35 – 20,000 Hz (±3 dB), capturing the full harmonic spectrum of instruments from bass through bright cymbals, while the 6.3 dBV / -100 dBm sensitivity ensures robust signal capture even in challenging RF environments.

System Flexibility & Connectivity

The BD7 band provides 1200 selectable frequencies across 500.1 – 530.5 MHz, supporting up to 20 simultaneous channels within the same band or 48 channels across multiple bands—giving you the flexibility to scale from solo performers to full band setups. Balanced XLR and unbalanced 1/4-inch outputs on the receiver accommodate any mixing console or interface, while the PT470 transmitter accepts standard 3-pin mini-XLR instrument cables and runs up to 14 hours on a single AA battery (alkaline, lithium, or rechargeable Ni-MH).
