Technical description of the Sennheiser ew-DX SK/SKM wireless digital system

The Sennheiser ew-DX SK/SKM is a high-quality, dual digital wireless microphone system designed for professional use. It combines a handheld transmitter (SKM) and a bodypack transmitter (SK), allowing for flexible deployment according to the user's needs. The system is supplied without a microphone head, allowing the user to choose the appropriate microphone for the specific application.

Frequency range and wireless technology

The system operates in the UHF band, which is known for its reliability and resistance to interference. It has up to 3520 tunable frequencies in an 88 MHz bandwidth, ensuring trouble-free reception even in densely occupied frequency areas. The system supports up to 148 channels in a single band, or 293 channels in LD (low delay) mode. Digital modulation minimizes noise, interference, and static discharge, maintaining the purity of the audio signal.

Receiver and transmitter hardware

Included is a robust two-channel rack-mount receiver equipped with two BNC antenna connectors and connectors for balanced (XLR) and unbalanced (6.3 mm jack) audio outputs. The receiver can be powered within the standard range of 11-13 V DC and supports PoE (Power over Ethernet) technology for powering via a LAN cable. Communication with transmitters also takes place via Bluetooth Low Energy, which allows for convenient control and configuration.

The SKM handheld transmitter is compatible with Sennheiser MMD, MME, MMK, KK, and MM microphones and is equipped with a MUTE switch for quick microphone muting. The SK pocket transmitter has a 3.5 mm jack for connecting various lapel or headset microphones. Both transmitters use BA 70 rechargeable batteries, which provide up to 12 hours of operating time, or alternatively run on standard AA batteries for approximately 8 hours.

Features and software options

The system can be automatically configured using the Smart Assist app, available for mobile devices running Android and iOS operating systems. For more demanding management, Sennheiser offers the Wireless Systems Manager and Control Cockpit programs for PC and Mac, which allow remote control of settings and monitoring of the status of transmitters and receivers. The sensitivity (gain) of the transmitters can be adjusted remotely, making it easy to quickly adapt the sound to the environment.

Technical parameters for sound and range

• Frequency response: 20 Hz to 20 kHz
• Dynamic range: 134 dB
• Total harmonic distortion (THD): less than -60 dB at 1 kHz
• Transmitter power: 10 mW, allowing a working range of up to 100 meters in open space
• Audio output level (XLR, balanced): up to +18 dBu
• Audio output level (jack, unbalanced): up to +12 dBu

Additional features and accessories

The system is equipped with an easily accessible MUTE switch for instant muting, a permanently visible e-ink display on the transmitter for clear parameter display, and PoE power support. The package also includes two rod antennas, a power supply, a rack mounting kit, and a microphone clip. A wide range of accessories allows the system to be customized to the specific requirements of each user.

Design and dimensions

The rack receiver measures approximately 212 x 44 x 189 mm and weighs around 1 kg without antennas and power supply, allowing for easy integration into professional audio setups. The transmitters are ergonomically designed for comfortable holding and carrying during long-term use.
