AKG WMS470 Sports Set BD7 Wireless Microphone System

For performers and presenters who need unrestricted movement without sacrificing audio fidelity, the AKG WMS470 Sports Set BD7 stands apart with its true diversity receiver, rugged body-pack transmitter, and feather-light C544 L head-worn microphone. Unlike entry-level wireless kits that suffer from dropouts and brittle sound, this system delivers studio-grade clarity on stage, in fitness instruction, or during live broadcasts—all within a reliable 100-meter operating range.

Highlights

• Complete wireless set: SR470 true diversity receiver, PT470 body-pack transmitter, and C544 L cardioid head-worn condenser microphone.
• BD7 frequency band (500.1–530.5 MHz) with up to 16 pre-programmed frequencies for interference-free operation.
• Infrared synchronization pairs transmitter and receiver in seconds—no manual frequency dialing.
• Switchable RF power (10 mW / 50 mW) adapts to venue size and local regulations.
• Backlit displays on both receiver and transmitter for clear status monitoring, even on dark stages.
• Runs up to 14 hours on a single AA lithium battery, reducing mid-show battery swaps.
• 19" rack mount kit included for permanent installations or touring racks.

In daily use

The C544 L head-worn microphone keeps the capsule consistently positioned at the corner of the mouth, delivering natural vocal tone with excellent rejection of ambient noise thanks to its cardioid polar pattern. The PT470 body-pack transmitter clips discreetly to a waistband or pocket, and its locking 3-pin mini XLR connector prevents accidental disconnects during energetic movement. On the receiver side, true diversity circuitry constantly compares two independent antenna signals, automatically selecting the stronger one to eliminate dropouts. Balanced XLR and unbalanced 1/4" outputs connect to any mixer, PA system, or camera audio input. With a frequency response from 35 Hz to 20 kHz and a signal-to-noise ratio exceeding 120 dB(A), speech and vocals come through with remarkable transparency and low noise.
