The Sennheiser EW-DP ENG SET (S1-7, article 700043) is a digital UHF wireless kit aimed at videographers, journalists and documentary crews who need to record both a lavalier and a boom or handheld microphone into one camera. The set contains the EW-DP EK portable dual-channel receiver, the EW-D SK bodypack transmitter with an ME 2 omnidirectional lavalier microphone, and the EW-DP SKP plug-on transmitter for XLR microphones. This S1-7 version tunes 606.2 - 662 MHz with up to 56 MHz bandwidth, and the digital link has 1.9 ms latency and 134 dB dynamic range, so levels are forgiving and distortion-free. Being UHF rather than 2.4 GHz, it offers better range and resistance to interference from Wi-Fi-heavy venues. The receiver mounts to a camera using the supplied cheese plate, which attaches via cold shoe or screws and holds the receiver magnetically. Batteries are exchangeable and the display shows remaining runtime, and settings can be managed with the Sennheiser Smart Assist app. It suits run-and-gun interviews, event coverage and corporate video. Check that 606 - 662 MHz is available for wireless mics in your area.
