The MSA+ family of products and reference designs is the bdSound top-grade solution for any Audio/Video intercom application. Based on a single ARM® Cortex® A7, running Linux as operating system, is a complete hardware and software solution for an Intercom and Communication Device.
MSA+ has been designed with a modular approach: stacking different boards it’s possible to create a custom solution with almost infinite possibilities and features. The MSA+ includes embedded web-gui and the proprietary audio and speech processing, together with echo canceller and noise reduction,
MSA+ is a product and a reference design that sums up the proprietary audio and speech processing, a reliable and a “ready to be a product” hardware design, and other software features.

MSA+ embed S2C – Simply Sounds Clear technology, the proprietary Speech Quality Enhancer processing by bdSound, every-day used by millions of communication endpoints. It includes:
S2C brings stunning audio quality in any communication application; MSA+ too.
MSA+ can be used with both single microphone or multiple microphones to significantly improve performance in communication quality and Automatic Speech Recognition, like Siri and Amazon Alexa.
Multiple microphones and beamforming technology dinamically adapt the microphone array behaviour to the room’s acoustics, background noise, reverberation, to isolate the actual talker.
MSA+ is a very flexible architecture with lot of possible applications and configurations. MSA+ can be set, controlled and tuned remotely from a graphical user interface.
It is also possible to embed a webgui into MSA+ thanks to the embedded web server.
Thanks to the modular approach it is possible to add multiple estensions, interfaces, features. MSA+ is a perfect structure to create complex, full-featured and tailored communication applications.
MSA+ has been designed with a modular approach. The Mother Board will connect, on both top and bottom side, to other boards, each one with its own features.
Thanks to this approach it is possible to create infinite products, with any desired features: power supply, ethernet switch, microphone array, high power audio amplifier, sensors board, leds, etc…
MSA family is composed by:
All the products are customizable on requests.
MSA+/MB is a full featured VoIP SIP intercom terminal, with several inputs and outputs. Based on a cheap ARM® Cortex® M7 processor, this product is compact, flexible, full-featured and with amazing audio quality, thanks to bdSound’s Speech Processing.
MSA+/PS1 is a power supply board that supports POE or external DC input. Fully compatible with the MSA+/MB, the PS also provides several features and functionalities. The MSA+/MB and MSA+/PS, together, is the minimum, yet fully featured, assembled system configuration to create a Video SIP intercom unit with a crystal clear audio quality thanks for the S2C embedded technology.
MSA+ has been designed with the expansion possibility in mind. A set of connectors helps to stack several boards on the same system, adding almost infinite possibilities.
Any MSA+/EB Expansion Board can be customized or designed according to customer’s requirements, adding all the peripherals required for the selected desired features.
The icon list here shows some of the possible features that can be added to the expansion board.
MSA+ is provided as stand-alone product or as a reference design to reduce your product development time with a reliable and tangible solution. A complete offer including hardware design, firmware and software, GUI, integration and electroacoustic design support.
