Product Details
✓Bundle Items Include: Sony UTX-B40 Wireless Bodypack Transmitter with Omni Lavalier Mic (UC14: 470 to 542 MHz), Sony ECM-77 Omnidirectional Lavalier Microphone, AA Batteries with Charger, Cable Ties, Microphone Cleaner, Microfiber Cloth
✓The Sony UTX-B40 is a compact, all-metal wireless bodypack transmitter designed for durability and comfort, offering up to 8 hours of operation on two AA batteries and selectable 5/30mW RF power with a transmission range up to 330'. It operates across a 72 MHz bandwidth with 2772 selectable UHF frequencies and is fully compatible with Sony URX-P40, WL-800, and UWP Series receivers.
✓Included with the UTX-B40 is the ECM-V1BMP omnidirectional lavalier microphone, optimized for speech and capable of capturing clear, natural vocal audio while allowing flexible placement. Sony’s proprietary digital audio processing enhances transient detail and consonant clarity beyond conventional analog companders, resulting in intelligible, nuanced sound suitable for professional video production.
✓Setup is extremely fast with NFC Automatic Channel Sync—press and hold the sync button on the receiver, let it scan for the cleanest channel, then hold the transmitter next to it for instant pairing. Auto-Gain mode helps prevent mic distortion by adjusting levels automatically, while Volume-Boost mode applies +15 dB gain for situations where the mic is positioned farther from the speaker’s mouth.
✓The UTX-B40 provides a high-visibility OLED display for easy monitoring in bright or dim environments, plus useful audio tools including a low-cut filter with 100/150/200 Hz settings, switchable mic/line input levels, and a programmable mute/talk button. Power is available via AA batteries or USB, and a built-in count-up timer tracks runtimes. Up to 16 mics can operate in one location.
