BEA3X-DSP Audio Card Bea3x


BEA3X-DSP: Powering Audio Excellence Through Advanced Processing

Unleashing Precision with DSP and FPGA Technology

The BEA3X-DSP card stands at the forefront of audio processing excellence. Its internal architecture is a marvel, powered by three DSP processors and a cutting-edge FPGA. This dynamic combination enables the card to execute a wide spectrum of processing tasks with unparalleled precision. Some aspects of the processing are performed in floating point, boasting resolutions surpassing 40 bits, while others are masterfully realized within the FPGA with comparable accuracy.

Guiding this powerhouse is a microcontroller that meticulously supervises and harmonizes the operation of various system components. While the card itself lacks external audio connections, it leverages the internal BUS, comprising 128 bidirectional channels, to seamlessly grant the system access to its formidable processing resources. This arrangement allows for the transmission of signals and retrieval of results, unlocking a realm of audio processing possibilities.

Technical Insights into BEA3X-DSP's Audio Processing Capabilities

Exploring Dynamic Configurations and Processing Blocks
The BEA3X-DSP card is a pinnacle of audio processing sophistication, and at its core lies an FPGA routing module that streamlines signal management among processing units, eliminating the need to occupy audio lines on the bus unless absolutely necessary. Internally it contains an FPGA routing module that allows to manage the signals locally between the various processing units without the need to occupy audio lines on the bus if not necessary. Each processing chain is fully configurable dynamically and can include the following processing blocks which can also be configured in different order for the different inputs to be processed:
  • Gain (digital, always included, it also allows phase inversion and LR-RL-LL-RR-Mono mode switching)
  • Pan/Balance
  • Dynamic processor (Compressor – Gate – Limiter)
  • 6 band parametric Eq
  • DeEsser
  • Delay (up to 2700ms)
  • Insert
  • Fader (with pre-fader and post-fader meters)
  • There are also several configurable tapping points available for each chain and can be used to route partially processed signals or create pre-fader auxiliary buses.

The management of the DSP processors is totally dynamic and allows you to reconfigure the chain in a different way by adding, removing, or changing the order of the blocks automatically every time an input is loaded on the bench according to the configuration saved for that input.

Each card is capable of handling 48 stereo processing chains from a 48 KHz mixer. The capacity can change according to the resources required.

Each card also features the stereo sum units necessary to create up to 128 stereo sums with 64 inputs each (in two blocks of 64 x 64 adders each as shown in the figure).

For each processing chain, the pre-fader and after-fader outputs are automatically connected to the summing unit, and each resulting bus also has a pre-fader output and an after-fader output that can be directed to the desired outputs.

Each of these buses can be used according to the configuration chosen by the user as program bus, record, auxiliary, mix-minus.

In addition to these in a DSP board are also available, 128 small summing units with independent inputs that are used to create monitor and talkback buses, 128 stereos to mono converter to allow stereo signals to be routed to mono outputs, 256 peak meters, 12 weighted stereo meters (3 switchable as loudness meter) and 4 generators configurable as tone, white noise, pink noise.
