Sennheiser EW-DX SK/SKM-S Base Set Combo Wireless Handheld and Bodypack Transmitter System - R1-9 Band (520-607.8MHz)

The Sennheiser 509463 is a ready-to-work wireless system that combines a handheld transmitter, a bodypack, and a half-rack receiver tuned to the R1-9 band from 520 to 607.8 MHz. It is built for sound engineers who need a dependable signal in venues such as live clubs, houses of worship, schools, or corporate conference rooms. With a usable range of up to 328 feet, presenters and performers can move freely without dropouts or cable clutter.

Getting the system on the air is quick. Press Auto Scan, let the receiver find the cleanest frequency, and you are set. If you prefer to manage multiple channels from a laptop or phone, Sennheiser Control Cockpit and Wireless Systems Manager give you full access to settings, battery status, and RF performance over a standard Ethernet network. AES-256 encryption keeps every word secure, which is essential for board meetings or confidential events.

The audio path offers a 134 dB dynamic range, so you rarely touch the gain knob, and latency of just 1.9 milliseconds keeps speech and performance in perfect sync. Both transmitters accept Sennheiser and Neumann microphone capsules, which means you can match the tonal character to the voice on stage. The bodypack works equally well with lavalier mics, headset mics, or a guitar cable, making the kit adaptable for drama productions, fitness instruction, or backline use.

Power management stays simple. Each transmitter runs up to 12 hours on the supplied rechargeable battery pack, and charging happens right in the device, so you do not have to hunt for a separate charger between shows. In Link Density mode, the receiver can handle large channel counts—up to 293 systems—allowing production teams to scale the rig without RF headaches.
