Anaheim, CA (January 23, 2015)—Sennheiser has launched evolution wireless D1, a line of 2.4 GHz range digital wireless microphone systems.
D1 operates in the 2,400 to 2,483.5 MHz range, which is license-free worldwide so there is no need to register the system or pay for the use of bandwidth. Region-specific particularities are catered for in the 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 move to another frequency if it detects interference.
D1 employs the aptX Live codec; overall latency is 3.9 milliseconds. Via the ew D1 menu control, bands have a range of audio effects at their disposal, including a 7-band graphic equalizer, low-cut filter, automatic gain control and de-esser. D1 vocal systems come with dynamic evolution microphone heads but can also be combined with the condenser capsules, which are available as accessories.
ew D1 systems coordinate themselves fully automatically. For multiple systems, receivers will synchronize themselves to accommodate up to 15 channels in an ideal RF environment.
Where local frequency regulations allow, such as in the USA and Canada, Sennheiser has fitted its evolution wireless D1 systems with adaptive transmission power, with up to 100 milliwatts of power. D1 transmitters can be powered by either standard batteries or rechargeable “accupacks” that are available as accessories. The rechargeable lithium-ion packs recharge via USB or a docking charger and the ew D1 system can be controlled by Apple or Android devices using a dedicated app.
