TRS connector that accommodates the compatible lavalier or headset microphone of your choice, or an adapter cable for guitar and bass.

Features at a Glance

• The EW-DX SK features a mute button that can be locked out and overridden from the receiver or a mobile device during a performance. It quickly pairs with the receiver via Bluetooth at a distance up to 120', at the press of a button.
• The persistent e-Ink display helps you quickly name and identify the transmitter and allows you to see parameters, even when the unit is powered off.
• The transmitter provides up to 8 hours of operation on two AA batteries (included) or 12 hours with a BA 70 lithium-ion rechargeable battery pack (available separately). External charging ports allow for in-transmitter charging using the CHG 70N network charging dock (available separately).
• The EW-DX system utilizes an equidistant tuning grid that equally spaces 3480 frequencies across its wide 87 MHz bandwidth to prevent disruptive intermodulation issues that occur when multiple transmitters operate in confined spaces.
• The system can be expanded with multiple transmitters and receivers to offer up to 146 channels in equidistant tuning grid mode, and up to 293 channels in Link Density mode.
• The EW-DX SK is backward-compatible with EW-D receivers.
