Sennheiser EW-D SKM-S Digital Handheld Transmitter

Sold without a capsule, the Sennheiser EW-D SKM-S is a digital handheld transmitter for Evolution Wireless Digital receivers, with a mute switch.

It takes Evolution Wireless Digital capsules from Sennheiser and Neumann, so you pick the head that suits the voice. Its 134 dB input dynamic range means there is no input sensitivity to set. Setup runs through the Smart Assist app over Bluetooth Low Energy, and auto scan finds clear frequencies.

Frequency Bands

This page offers three US bands: Q1-6 (470.2 to 526 MHz), R1-6 (520 to 576 MHz), and R4-9 (552 to 607.8 MHz). Each band covers 56 MHz with up to 90 channels. The signal is digital, so channels sit on an even 600 kHz grid.

Power

The SKM-S runs up to 8 hours on the two included AA batteries, or up to 12 hours on a BA 70 rechargeable pack, sold separately.
