AKG WMS470 Sports Set BD1 - UHF Band 1 Wireless System with PT470 Bodypack, C544 L Headset Microphone and SR470 Receiver

The AKG WMS470 Sports Set BD1 is a professional UHF wireless system designed for fitness, aerobics, gyms , and all kinds of hands-free applications on stage and in education. The set combines the SR470 receiver , PT470 bodypack , and C544 L headworn microphone (moisture-resistant cardioid condenser), delivering clear audio, feedback rejection, and a stable behind-the-neck mount for intense sessions. The BD1 Band 1 operates across 650.1–680 MHz , and the WMS470 platform offers pilot tone to avoid start-up noise, IR synchronization , and auto-setup with channel preview , facilitating fast and reliable deployment in mobile environments or fixed installations.

Main features

• C544 L headworn microphone with cardioid condenser capsule , moisture protection , and shock mount to minimize mechanical noise; 80–20,000 Hz response and approximately 25 mV/Pa sensitivity.
• PT470 transmitter (beltpack) with up to 14 hours of battery life on a single AA battery, built-in charging contacts , and infrared for copying receiver data; selectable RF power up to 50 mW (as per regulations).
• SR470 receiver with microprocessor-controlled diversity, balanced XLR outputs (switchable −30/0 dB) and unbalanced 6.3 mm jack , audio bandwidth of 35–20,000 Hz , S/N 120 dB(A) and THD <0.3 % .
• Multi-channel operation : up to 20 simultaneous channels on the same band (up to 48 by combining multiple bands); 30.5 MHz tuning width with 1,200 available frequencies and up to 16 presets per band for immediate start-up.
• Connectivity and mounting : 2 antennas with BNC connectors, 1U format and half 19” rack with anchoring kit included.
• Set contents : SR470, PT470, C544 L, universal power supply with US/UK/EU adapters, 2 antennas, rack kit and AA battery.
• Band BD1 (Band 1) : 650.1–680 MHz for countries/regions where permitted. Always check local spectrum regulations.

Product benefits

• Freedom of movement and stability : The C544 L headband remains firm even with sudden movements; its moisture-wicking barrier protects the capsule from sweat.
• Clear, consistent sound : cardioid pattern to isolate voice, true diversity on the receiver and pilot tone to suppress unexpected noise.
• Low operating costs : up to 14 hours with an AA battery; battery life displayed in hours and NiMH charging directly in the belt pack (with a compatible charger).
• Quick Deployment : IR sync, per-band presets, and channel preview simplify frequency coordination for group events and classes.

Use cases

• Gyms and sports centers : directed fitness classes, cycling, Zumba, HIIT.
• Education and training : multipurpose rooms, pavilions and auditoriums.
• Events and live performances : instructors/trainers at trade shows, conventions, and on-stage demonstrations.

Frequently Asked Questions

How many WMS470 systems can I use at once? Up to 20 simultaneous channels can operate on the same band , and up to 48 can operate using multiple bands, provided frequency coordination and the RF environment allow.

What is the difference between BD1, BD7, or BD8? They are frequency band variants: BD1 (Band 1) 650.1–680 MHz; BD7 (Band 7) 500.1–530.5 MHz; BD8 (Band 8) 570.1–600.5 MHz. Availability and legality vary by country.

Does the C544 L work with other AKG bodypacks? Yes, the C544 L features a 3-pin mini-XLR connector and is compatible with AKG wireless bodypacks that supply power for electret capsules.
