New Link Density Mode to help in congested spectrum

Sydney/Anaheim, January 17, 2020 – In the face of ever shrinking UHF spectrum available for the program-making and special events (PMSE) sector, Sennheiser is launching a “Link Density Mode” for its Digital 6000 wireless microphone series. “Virtually everywhere the world over, production companies, theatres and touring artists and their engineers have lost more UHF spectrum than can be compensated for,” explained Tom Vollmers, Manager for the Professional Portfolio at Sennheiser. “With the Link Density Mode for Digital 6000, we are providing greater leeway to PMSE professionals while continuing our joint efforts to secure frequency spectrum that is so urgently needed for productions.”

The new Link Density (LD) Mode significantly increases the number of links that can be operated in congested RF environments. While the standard Long Range Mode of Digital 6000 operates with a 400 kHz channel spacing to ensure best audio and RF performance, the LD Mode uses half of the spacing, i.e. 200 kHz. This means that up to 40 links can be accommodated in an 8-MHz TV channel in Europe, and up to 30 links in the smaller 6-MHz TV channel in the USA.

Giving engineers a choice
​Behind the LD Mode is the new Sennheiser Performance Audio Codec (SePAC) which has been designed by Sennheiser’s developers to strike a new balance between channel count on one hand and RF and audio performance on the other.
​​
​“The LD Mode provides productions with a choice where there simply was none before,” said Vollmers. “They are now able to increase the number of channels by accepting slight trade-offs in the audio frequency response and RF range. This can be a good solution for applications that only have very limited spectrum at their disposal.”

Codec comparison and firmware update information

The new LD Mode will be made available free of charge via a firmware update from January 16, 2020 at www.sennheiser.com/download. It can be used with all existing Digital 6000 systems in the market except for the EK 6042 camera receiver, which will not support LD Mode.
​​
​“For those visiting NAMM, we will have the new firmware version at the booth and will be happy to provide you with a demonstration,” added Vollmers.
