Sennheiser Demos Wireless D1 Range At BVE

Sennheiser will be demoing its evolution wireless D1 range at this year's BVE show in London.

Recently launched at NAMM, D1 is a range of digital wireless microphone systems. Transmitters and receivers automatically pair and select suitable transmission frequencies, while multiple D1 systems can automatically coordinate themselves. ew D1 operates in the 2.4 GHz range, which is license-free worldwide.

D1 undertakes selections on behalf of the user, from frequency setting, matching transmitters and receivers, to getting the gain right.

License-free 2.4 GHz transmission with intelligent channel management
D1 operates in the 2,400 to 2,483.5 MHz range, which is license-free worldwide. Region-specific particularities are catered for in respective country variants.

To allow co-existence with Wi-Fi, Bluetooth and other 2.4 GHz systems, the D1 receiver continually scans the RF environment, and will inaudibly and seamlessly hop to another frequency if it detects any interference. Two channels are always available: besides the actual audio transmission channel, the system runs a redundant back-up channel, thus providing frequency and time diversity. Transmission reliability is further increased by fast-switching antenna diversity.

Evolution wireless D1 employs aptX Live codec for audio quality. Overall latency is a low 3.9 milliseconds, which is suitable for wireless monitors are to be used.

Via the ew D1 menu control, bands have a range of audio effects at their disposal. These include a 7-band graphic equalizer, low-cut filter, automatic gain control and de-esser. The D1 vocal systems come with dynamic evolution microphone heads but can naturally also be combined with the condenser capsules from the acclaimed series, which are available as accessories.

D1 transmitters can be powered by either standard batteries or rechargeable 'accupacks' that are available as accessories. These rechargeable lithium-ion packs recharge via USB or a docking charger.
