SENNHEISER RADIOMICS - Evolution Digital

Sennheiser EW-D (Evolution Wireless Digital) series of radio systems are available as complete systems or in component form with either handheld transmitters or belt-pack transmitters for use with instruments or lapel microphones. The technology utilised in these digital wireless systems allows the user more scope to build, with up to 24 wireless systems per frequency range. A 56MHz bandwidth will allow up to 90 channels of EW-D. This is achieved by using the same equidistant tuning grid technology that is present in the Sennheiser Digital 6000 and Digital 9000 systems. The user can employ Sennheiser’s Smart Assist app to remotely setup and monitor up to 16 EW-D systems in the chain via Bluetooth.

As this series of wireless systems are not compatible with Sennheiser Evolution G4 analogue wireless systems, to avoid confusion, the available frequency bands for the digital systems have been given new frequency range names. Therefore the following denotes which band represents which frequency range:

Band Frequency Range
S1-7 606-662MHz (including channel 38)
U1/5 825-832/863-865MHz (including channel 70)

Alternative frequencies/channels are available to order. Please contact our Sales team for more information.

A licence is required to operate this equipment in channel 38.
For more information in regards UK wireless system licensing and OFCOM, please visit the Canford guide at http://www.canford.co.uk/Technical/Article/Channel69; Up to date information should be available at https://www.ofcom.org.uk/manage-your-licence/radiocommunication-licences/pmse

Usage Note: Licensing and legal use information for radiomic equipment in this product group is applicable to the UK only. Customers should check with the relevant regulatory body for the territory the equipment is to be used in prior to purchase to ensure appropriate legal usage and local environmental restrictions.
