Stagetec's new DSP board for Nexus

Stagetec introduced a new generation of its signal-processing board XDSP for Nexus at IBC. Billed as being as compact and lightweight as its predecessor, the new board quadruples processing power and integrates the ISOSTEM upmix system invented by Berlin-based DSpecialists.

The new Nexus XDSP board opens up new possibilities for audio signal processing within Nexus: for example, now up to 20 minutes delay, up to 66 30-band equalizers or up to 320 dynamic units can be realised per board. As before, all signal-processing modules can be combined individually according to the customer requirements meeting the demands of the most complex applications. Regardless of this improved performance the XDSP remains compact. Like its predecessor it requires only a single 4 HP grid in a 3U Base Device thus boosting significantly the efficiency and productivity of the overall system.

Another world first for Nexus systems with the latest XDSP is the ISOSTEM upmix algorithm by DSpecialists incorporated into the board. Designed for applications where multichannel mixes based on stereo are part of the everyday work – for example in broadcast environments or in post-production – the ISOSTEM algorithm generates a perfect 5.1 mix from stereo input signals in real time that is fully reversible. Devices that are unable to play back (or to transmit) multichannel will receive the unadulterated stereo signal the multichannel mix was based on. This world exclusive method was patented for DSpecialists and is available as an option with the new XDSP board.

The ISOSTEM integration in the Nexus works with a series of factory presets. They generate high-quality upmixes from various sources at the press of a button, thus ensuring a substantial increase in productivity, for example when editing archived material in broadcasting. Individual presets can be created using the ISOSTEM hardware version “Expert” and imported to the XDSP board.

Happily, the XDSP module is fully backwards compatible. The board is scheduled to hit the market at the end of  Q4.
