Microphones capture more than speech.
They also capture room reflections, background noise, changes in talking distance, loudspeaker sound and competing voices.
Commercial AV Technology Guide
Discover how digital signal processing improves speech clarity, removes conferencing echo, manages microphones and routes audio across modern commercial AV systems.
DSP explained
A digital signal processor receives audio, improves it, routes it and delivers the correct signal to conferencing platforms, amplifiers, recording systems and loudspeakers.
They also capture room reflections, background noise, changes in talking distance, loudspeaker sound and competing voices.
Mixing, equalisation, echo cancellation, noise reduction, routing and gain management create clearer and more consistent audio.
A DSP can be a dedicated audio processor, part of a broader audio-video-control platform or software operating on an approved computing environment.
Masters Voice Technology integrates DSP platforms within complete commercial audio visual installations for corporate, education, government, venue and worship environments.
Commercial DSP Platforms
The right digital signal processor should be selected around the room workflow, microphone and loudspeaker count, conferencing platform, network architecture, control strategy, monitoring requirements and future expansion—not simply the brand name.
Q-SYS combines digital signal processing, video, conferencing, room control, cameras, paging and monitoring within a unified software-based platform.
Core Nano, Core 8 Flex, Core 110f and larger processors support different combinations of network audio, analogue I/O, USB connectivity and system scale.
Strong fit for meeting rooms, education, government, paging, divisible spaces and remotely managed AV systems.
Crestron environments can combine room control, collaboration, AV distribution and network audio within a standardised enterprise technology platform.
DM NAX provides network-based audio distribution, processing, routing and zone management for compatible Crestron-controlled environments.
Strong fit for enterprise workplaces, multi-zone audio, Crestron-controlled rooms and standardised corporate AV.
The BLU-100 provides 12 analogue inputs, eight analogue outputs, configurable signal processing and BLU link digital-audio connectivity.
Its open architecture supports custom routing, zoning, priorities, room presets and venue-specific commercial audio workflows.
Strong fit for pubs, clubs, hotels, function rooms, entertainment venues and established Harman systems.

Tesira includes fixed and configurable processors for acoustic echo cancellation, conferencing, enterprise audio, USB, Dante and AVB system designs.
Different models support applications ranging from focused meeting rooms to larger connected audio environments.
Strong fit for boardrooms, higher education, courtrooms, conferencing suites and enterprise audio systems.
Solaro processors provide configurable signal processing and modular I/O for analogue audio, USB, Dante, GPIO and commercial room-control integration.
Compact and rack-mounted models support room-based, centralised and higher-channel-count commercial AV applications.
Strong fit for classrooms, courtrooms, collaboration spaces and flexible commercial meeting environments.
The P300 provides acoustic echo cancellation, automixing, noise reduction, automatic gain control and conferencing processing for Dante microphone channels.
It integrates closely with Shure Microflex Advance and other compatible networked microphone systems.
Strong fit for boardrooms and meeting rooms using Shure ceiling, table or networked conferencing microphones.

Commercial DSP design and integration
Masters Voice Technology designs, programs and supports DSP-based AV systems for meeting rooms, schools, government facilities, venues, worship spaces and multi-site organisations across Sydney and regional New South Wales.
For a DSP assessment, send the room layout, microphone and loudspeaker details, existing processor model and the audio workflows you need. Describe echo, feedback, coverage or level problems, and include available drawings or configuration records so the assessment can distinguish system tuning, programming and hardware requirements.
