AKG WMS470 INSTRUMENT SET BD7 - Professional Wireless Microphone Syste
Description
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.

Frequently Asked Questions
What instruments can I use with the WMS470?
The PT470 transmitter accepts standard 3-pin mini-XLR instrument cables, so it works with any instrument using that connector type—guitar, bass, keyboard, and more. The audio bandwidth spans 35–20,000 Hz, capturing the full harmonic spectrum across a wide range of instruments.
How many channels can I run at the same time?
The BD7 band provides up to 20 simultaneous channels within a single band, or you can expand to 48 channels total by using multiple bands. The system includes 1200 selectable frequencies across 500.1–530.5 MHz for flexible frequency coordination.
How long does the battery last?
The PT470 transmitter runs up to 14 hours on a single AA battery—alkaline, lithium, or rechargeable Ni-MH cells all work. This gives you a full day of gigging or studio sessions on one charge.
What outputs does the receiver have, and will it work with my mixer?
The SR470 receiver provides both balanced XLR and unbalanced 1/4-inch outputs, so it connects to any mixing console, audio interface, or PA system. The 1/2 19-inch 1U rack format fits standard studio and live rigs.
How transparent is the audio, and will I hear signal loss?
The WMS470 delivers less than 0.3% total harmonic distortion with a 120 dB signal-to-noise ratio, ensuring transparent reproduction with virtually no audible coloration or noise. The wideband FM modulation and microprocessor-controlled diversity circuit maintain signal integrity even in challenging RF environments.
