Product details
Overview
What is the Sennheiser EW-DX SK?
The Sennheiser EW-DX SK is a digital wireless bodypack transmitter with a 3.5 mm jack for Sennheiser lavalier and headset microphones, built for Evolution Wireless Digital receivers. It offers 1.9 ms latency, a 134 dB dynamic range and up to 12 hours of runtime in a 63.5 × 85 × 20 mm metal housing, which suits presenters, trainers and stage performers in UAE conference rooms, classrooms and theatres.
The Sennheiser EW-DX SK is the bodypack transmitter of the Evolution Wireless Digital EW-DX family. It is delivered without a microphone, so the buyer chooses a compatible lavalier or headset with a 3.5 mm jack. A programmable mute switch, an always-on E-Ink display and function buttons let the user set the transmitter directly. A separate EW-DX SK 3-PIN version exists for microphones with a 3-pin connector.
Why this product
Key Benefits
-
Works with many Sennheiser microphones
The 3.5 mm jack takes lavalier models such as the ME 2, ME 4, MKE Essential, MKE 2 and MKE 1, and headset models such as the ME 3, HSP Essential, HSP 2, HS 2 and Headmic 1.
-
Low-latency digital audio
The Sennheiser Performance Audio Codec (SePAC) gives 1.9 ms system latency and a 134 dB dynamic range, so the gain does not have to be set for each speaker.
-
Programmable mute switch
The switch can mute the radio signal or the audio signal, or it can be disabled to prevent accidental muting.
-
Instrument input with cable emulation
The input can simulate cable characteristics when a guitar or other instrument is connected.
-
Always-on E-Ink display
Frequency, battery and encryption status stay visible even when the batteries are removed, and the function buttons can be locked.
-
Rechargeable or AA power
A BA 70 pack gives up to 12 hours and charges in the transmitter through its charging contacts in the CHG 70N-C, while two AA batteries are included for up to 8 hours.

Applications

Installation & Mounting
Recommended Microphone
The Sennheiser ME 4 Cardioid Condenser Lavalier Microphone is on Sennheiser's compatibility list for the EW-DX SK (ME 4 models produced from 2021 onward with a gold-plated connector). It adds a cardioid pattern for noisier rooms; check the production year before using it with this transmitter.
Recommended Receiver
The EW-DX SK needs an Evolution Wireless Digital receiver on the same frequency range. See the Sennheiser EW-DX EM 2 2-Channel Wireless Receiver for two channels, or the Sennheiser EW-DX EM 4 DANTE 4-Channel Wireless Receiver for four channels with Dante. Choose Q1-9 or R1-9 to match.
