Sennheiser EW-DP SKP Digital Plug-On Wireless Transmitter/Recorder

Product Overview

The Sennheiser EW-DP SKP is a professional digital plug-on XLR transmitter designed for the EW-DP wireless platform, turning any XLR microphone into a wireless source. Built for broadcast ENG crews, boom operators, and documentary filmmakers, the SKP delivers 24-bit digital audio with just 1.9 ms of latency over UHF. It also doubles as a fully standalone 32-bit float recorder to microSD, giving operators a simultaneous backup recording with no clipping — even in the most unpredictable sound environments.

The EW-DP SKP plugs directly into the XLR output of any dynamic or phantom-powered condenser microphone, supplying 48V phantom power so shotgun mics and high-end lavs work without any additional hardware. A secondary 3.5 mm locking TRS input accommodates lavalier microphones, adding further versatility in the field. The unit operates across a wide 56 MHz UHF bandwidth with an equidistant frequency grid, enabling clean frequency coordination alongside up to 90 simultaneous channels. Bluetooth 5.1 connectivity pairs the SKP with the Sennheiser Smart Assist app for fast, remote configuration directly from a smartphone — a major time-saver on busy sets. The internal antenna keeps the form factor compact and snag-free when rigging to a boomed microphone. Frequency band options cover Q1-6 (470–526 MHz), R1-6 (520–576 MHz), and R4-9 (552–608 MHz), allowing operators to choose the cleanest spectrum for their region. Two AA batteries power the unit in the field, while USB-C charging keeps topped-up batteries ready between takes. The EW-DP SKP is compatible with all EW-D and EW-DP series receivers, making it a seamless addition to any existing EW-DP rig or as a standalone upgrade for operators who already own a compatible receiver.

Technical Specifications

Frequently Asked Questions

Q: What receivers is the EW-DP SKP compatible with?

The SKP is compatible with all EW-D and EW-DP series receivers, including the EW-DP EK camera-mount receiver and EW-DP EM 2 rackmount receiver. Make sure the frequency band of your SKP matches the receiver's band.

Q: Does the EW-DP SKP work with condenser microphones?

Yes. The SKP supplies 48V phantom power through its XLR input, making it fully compatible with condenser microphones including shotgun mics like the Sennheiser MKH 416.

Q: Can I use the SKP as a standalone recorder without a receiver?

Yes. Insert a microSD card (sold separately) and the SKP records 32-bit float audio independently of the wireless link. This is ideal as a backup track or for situations where wireless RF is not needed.

Q: How do I set up the SKP remotely?

Download the free Sennheiser Smart Assist app for Android or iOS, enable Bluetooth on your phone, and the app will detect the SKP for frequency scanning, sync, and gain adjustment.

Q: How many SKP transmitters can operate simultaneously?

Up to 90 EW-DP systems can operate simultaneously within the same frequency band, thanks to the equidistant 56 MHz grid and intelligent auto-scan.

Q: What battery type does the SKP use?

The SKP uses two AA batteries. Standard alkaline or rechargeable NiMH AA cells are both compatible.

Q: Which frequency band should I choose?

Choose based on the UHF spectrum available in your country or region. Q1-6 (470–526 MHz) is popular in the US. Check local regulations and use a frequency scanner to find the cleanest band at your location.

Q: Is the EW-DP SKP sold as part of a complete system?

The SKP is sold as a standalone transmitter/recorder. Pair it with the EW-DP EK camera-mount receiver (available at creationnetworks.net) or another compatible EW-DP receiver to build a complete wireless system.
