About Sennheiser EW-DX SK

Just imagine the freedom and flexibility of a wireless system that delivers high-quality sound without compromise. The Sennheiser EW-DX SK Digital Wireless Bodypack Transmitter, operating in the Q1-9:470 - 550 MHz frequency range, is designed to do just that. This lightweight, yet robust, all-metal bodypack transmitter is compatible with EW-DX wireless receivers, making it an ideal choice for performers, presenters, and professionals in conference rooms, houses of worship, or on stage.

The EW-DX SK is equipped with a secure, locking 3.5mm TRS connector, accommodating a wide range of compatible lavalier or headset microphones, or even an adapter cable for guitar and bass. Its impressive 134 dB dynamic range on input allows it to handle a diverse array of sound sources, from powerful vocalists and performers to musical instruments and line-level signals from mixers, all without the need for gain adjustment.

One of the standout features of the EW-DX SK is its mute button, which can be locked out and overridden from the receiver or a mobile device during a performance. The transmitter pairs quickly with the receiver via Bluetooth, with a range of up to 120 feet, at the simple press of a button.

The persistent e-Ink display on the EW-DX SK allows for quick identification and parameter viewing, even when the unit is powered off. The transmitter offers up to 8 hours of operation on two AA batteries, or up to 12 hours with a BA 70 lithium-ion rechargeable battery pack. External charging ports facilitate in-transmitter charging using the CHG 70N network charging dock.

The EW-DX system employs an equidistant tuning grid, spacing 3200 frequencies across an expansive 80 MHz bandwidth to prevent disruptive intermodulation issues. This system can be expanded with multiple transmitters and receivers to offer up to 134 channels in equidistant tuning grid mode, and up to 269 channels in Link Density mode.

The EW-DX SK is also backward-compatible with EW-D receivers. It works seamlessly with a variety of mics and instrument cables with a locking 3.5mm TRS Connector, including the sweat-resistant MKE 2 omnidirectional lavalier mic, the unobtrusive ME 2 omnidirectional lavalier mic, the ME 4 cardioid lavalier mic, the ME 3 cardioid headset mic, and the CI 1 instrument cable. With the Sennheiser EW-DX SK Digital Wireless Bodypack Transmitter, you can experience the freedom of wireless without sacrificing sound quality.
