Characteristics and Core Functions

Professional expansion microphones are designed to complement existing audio systems. They extend audio coverage without requiring full equipment replacement. Ideal for progressively scaling infrastructure as rooms grow or layouts change, they capture voices in all directions and ensure consistent, even sound distribution.

Main system compatibility Specifically designed for existing brands and systems.
Optimised capture Beamforming microphones clearly capture voices from positions further away from the main system.
Guaranteed extended range Significant increase in audio coverage area.
Consistent audio quality Uniform processing with the main system for a consistently balanced audio experience.
Wired and wireless options Flexibility depending on cabling constraints and variable table configurations.

How to choose the right solution?

  • OKInstalled main system: exact compatibility with brand and model to guarantee seamless integration.
  • OKRequired coverage extension: number of additional participants and distance from the main system.
  • OKRoom configuration: long single table or multiple dispersed tables requiring varied microphone placement.
  • OKAvailable cabling: wired installation or need for flexible wireless solutions.
  • OKNumber of microphones required: calculated according to desired coverage and maximum capacity supported by the main system.
Professional expansion microphones

Applications across professional environments

Expansion microphones are used in large meeting rooms to capture voices from participants seated further away from the main system. For growing organisations, they enable gradual extension of existing infrastructure without immediate major investment. In training centres with large groups, they ensure equal audio participation regardless of seating position. In event environments, they temporarily increase system capacity for occasional conferences with unusually large audiences.

Why partner with Onedirect?

Onedirect offers professional expansion microphones from leading brands such as Poly, Logitech, Jabra, Yealink and Konftel. As an official reseller, we ensure fast and secure delivery supported by permanent stock availability. Our team advises you on compatibility with installed systems and the optimal number of microphones for your rooms, ensuring a successful audio extension.

FAQ – Frequently asked questions

How can I check if my audio conferencing system supports expansion microphones?

Consult the technical documentation of the main system. Most professional systems support extensions, with a maximum number of microphones specified by the manufacturer.

Do expansion microphones need to be from the same brand as the main system?

This is strongly recommended to ensure full compatibility and optimal audio quality. Generic microphones may cause compatibility issues or reduced overall audio performance.

What is the maximum distance between an expansion microphone and the main system?

For wired microphones, this is typically up to 10–15 metres depending on the supplied cable. Wireless microphones offer greater flexibility, with typical ranges of 15–30 metres.

Can wired and wireless microphones be mixed on the same system?

This depends on the system. Some support mixed configurations, while others require uniform microphone types. Always check manufacturer compatibility before purchasing.

Are these microphones suitable for small rooms?

They are primarily designed for large rooms, but can also enhance audio quality in medium-sized spaces.
