AKG WMS470 Instrument Set BD7 Professional Wireless Microphone System

The AKG WMS470 is a professional-grade wireless system engineered for studio tracking and live recording sessions where sonic transparency and RF reliability are non-negotiable. This body-pack transmitter system captures your instrument's natural tone and detail with consistent wireless performance, freeing you from cable constraints during overdubs, rehearsals, or remote recording setups. Built on AKG's reputation for legendary engineering, the WMS470 has proven itself across countless professional sessions and touring applications worldwide.

Audio Performance & Wireless Architecture

The SR470 receiver operates on wideband FM modulation 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 that sits cleanly in your mix. 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 within the studio or tracking space.

System Flexibility & Studio Integration

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—enabling flexible multitrack recording setups from solo sessions to full ensemble tracking. Balanced XLR and unbalanced 1/4-inch outputs on the receiver integrate seamlessly with any mixing console or audio 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), eliminating mid-session battery swaps.
