Microphone Sennheiser EW-D EM (Q1-6)

The Sennheiser EW-D EM (Q1-6) is a professional digital wireless microphone system designed for singers, speakers and instrumentalists who require reliable live sound. The receiver provides digital transmission in the UHF spectrum, wide tuning bandwidth and flexible frequency selection to ensure clear audio and stable connections for live performances, presentations and broadcast applications.

Advantages

Digital UHF transmission improves range, reliability and scalability compared with older analogue systems. Integration with the EW-D Smart Assist App via Bluetooth Low Energy enables remote pairing, auto scan and simplified system management. A 134 dB audio input dynamic range preserves signal detail without frequent sensitivity changes, while intermodulation elimination and equidistant 600 kHz channel spacing allow for dense, predictable channel placement. Extensive tuning options — including 56 MHz bandwidth, up to 90 channels and 2,240 selectable frequencies — offer fine frequency control. Power options include a Lithium‑Ion battery pack (sold separately) giving up to 12 hours of operation or two AA batteries for up to 8 hours.

Suitable for

• Live vocal performances
• Presentations and conferences
• Instrument amplification on stage

How to use

Install the receiver in a suitable rack or on a stable surface and connect its audio outputs to your mixing console or amplifier. Power the receiver using the recommended battery pack or AA batteries, then power on the transmitter and receiver. Use the EW-D Smart Assist App or the receiver front‑panel controls to perform an auto scan and pair transmitter and receiver. Adjust input gain on the transmitter if necessary and set output levels at the mixer. Verify signal quality and RF indicators before the performance.

Usage recommendations

For best results, keep line of sight between transmitter and receiver where possible, use the Smart Assist App to perform automatic scans in the venue environment, and prefer the Lithium‑Ion battery pack for extended continuous operation. Avoid placing the receiver near large metal objects or sources of strong RF interference.
