What is the maximum room size a tabletop speakerphone can cover?

A: Quality speakerphones cover 3–8 metres diameter; rooms above 6 metres in length require additional microphone extension units or a ceiling array system.

What is a DSP processor in an audio conference system?

A: A DSP (Digital Signal Processor) is the central audio engine that performs AEC, noise reduction, mixing and routing – essential for professional-grade conference rooms.

Are wireless microphones legal to use in India without a licence?

A: WPC-approved wireless microphones operating in the 470–698 MHz UHF band or 2.4 GHz ISM band are legal; other frequencies require individual WPC licensing.

What is the difference between beamforming and omnidirectional microphones?

A: Beamforming mics use digital signal processing to focus on voice direction while rejecting off-axis noise; omnidirectional mics pick up all sound equally in 360 degrees.

Can I use one ceiling microphone for a large boardroom?
