Lawo’s UHD Core Packs Over 1,000 IP DSP Channels Into One Rack Unit

At the 2018 IBC Show, Lawo will introduce a network-based, software-defined, audio DSP engine called UHD Core that features significantly increased signal processing density in order to expand the usability of its mc2 56 and mc2 96 audio mixing consoles. Due to a flexible licensing model, the UHD Core is ideal for both mobile applications and facility use.

Utilizing an IP network as an extension of the console core’s backplane, Lawo’s new UHD Core can be located anywhere on the network. Its ultra-high processing density—with more than 1,000 mc2 fully featured DSP Channels—can either be utilized by a single mc2 console for coping with even the most challenging productions or be shared amongst up to four consoles. The UHD Core’s functionally is defined by software, so updates and networking scalability are easily performed and ensured.

For mobile productions the scalable DSP performance of the UHD Core can be accessed with a temporary license that turns Capex into Opex, while in facility applications resource pooling and flexible allocation of DSP resources to multiple consoles can significantly increase the utilization of the audio infrastructure investments.

The UHD Core features low-noise cooling in a rack-mountable box. Eight independent 10/1GbE network interfaces with SFPs enable the use of redundant networks via ST2022-7 seamless protection switching (SPS). An UHD Core‘s total network I/O capacity equals 40,000 48kHz/24bit audio channels. For signal management the unit provides two redundant RJ45 1GbE management ports. Full hardware redundancy is assured with a second “hot spare unit” that permanently mirrors all settings.

The system latency is comparable with conventional architectures connected via the backplane: a special high-performance RAVENNA profile provides network round-trip latency in the sub-millisecond range while the processing power and speed of the UHD core outperforms the processing latency of multiple DSP devices.
