Frequently Asked Questions

Digital transmission eliminates much of the noise and interference common with analog, resulting in a cleaner, more consistent signal – a significant upgrade for reliability.
The ew-D series uses a different protocol than previous Sennheiser wireless generations, so it’s not backward compatible – you’ll need a compatible ew-D transmitter.
Expect a typical operating range of around 150-200 feet, but this is highly dependent on environmental factors like obstacles and RF congestion.
