What is the PeopleLink DSP CM?

The PeopleLink DSP CM is a Ceiling Microphone System pairing suspended spherical microphones with a master receiver that carries a built-in Digital Audio Processor. It captures voice hands-free in Conference Rooms, Classrooms and Training Rooms, so no cables run across the table. AEC, AGC and ANS run on the receiver, which means the far end hears speech rather than room noise and echo.

What room size does the Ceiling Microphone System cover?

Each microphone has a 360 degree pickup radius of 10 metres, and the system supports two microphones, which suits rooms of roughly 80 to 100 square metres and 15 to 30 seats. Ceiling mounting means coverage comes from above the seating rather than from a device someone has to sit near. For an unusual room shape, ask a PeopleLink AV Specialist to place the two microphones before installation.

How does the Ceiling Microphone System connect to a room PC?

The master receiver connects over USB 2.0 Type B and also carries a Phoenix 2-way 3.81 mm interface, and it is supported on Windows and Mac OS. To the room PC it appears as the microphone, so it serves common Video Conferencing platforms without extra software. An Active Speaker can be added for local amplification in the room.

Will the PeopleLink DSP CM work with my existing Video Conferencing platform?

Yes. The master receiver connects to a room PC over USB 2.0 Type B and is supported on Windows and Mac OS, so it serves as the microphone for common Video Conferencing platforms, and an Active Speaker can be added for local amplification. Share your platform and room details with a PeopleLink specialist to confirm the setup.

Who installs and supports the system?

Installation, service and support are delivered through PeopleLink Partners and Resellers in your region, with PeopleLink AV Specialists supporting them on sizing and integration. Because the microphones suspend from the ceiling and the receiver sits with the room PC, most rooms can be fitted without rebuilding the table or the furniture.

How does a Ceiling Microphone System fit a multi-site or campus rollout?

Rooms of 80 to 100 square metres take the same two-microphone layout, so a campus or a training network can be sized from a room list rather than surveyed room by room. The receiver connects over standard USB to whatever PC the site already uses, which keeps the software side unchanged. Regional PeopleLink Partners handle installation and support at each location.

Overview

What a Ceiling Microphone System does in a Conference Room or Classroom

The PeopleLink DSP CM is a Ceiling Microphone System for Conference Rooms, Classrooms and Training Rooms seating 15 to 30 people. Two suspended spherical microphones each give a 360 degree pickup radius of 10 metres, covering rooms of 80 to 100 square metres with nothing on the table. The master receiver adds a built-in Digital Audio Processor with AEC, AGC and ANS, Intelligent Remix and a 75dB signal-to-noise ratio, connecting over USB 2.0 Type B on Windows and Mac OS. An Active Speaker can be added for Local Sound Reinforcement. Ceiling mounting means an existing room can be upgraded without changing the furniture.

Features

High-Performance Full-Coverage Pickup Microphones

DSP-CM Microphones are high-performance full-coverage pickup microphones for normalized recording and playback in classrooms and remote interactive scenarios. A single microphone covers a radius of 10 meters, and two microphones can cover a classroom or conference room with an area of over 120 square meters.

Features

Ceiling Microphones for Any Meeting Space

The ceiling microphone is designed for easy ceiling mounting and suits diverse meeting spaces, including training rooms, classrooms, and demo rooms. Its discreet placement ensures effective audio coverage, making it an ideal solution for enhancing collaboration in professional environments.

Features

Digital Array Microphone, Long-Distance Voice Pickup

The microphones adopt large-size and professional-grade acoustic transducers to capture a wide dynamic range and can pick up rich and full-bodied sound from up to a 10-meter radius. Lecturers or conference speakers can speak anywhere within 2-10 meters from the omnidirectional microphone without affecting the pickup effect.

Features

Design and Installation

The design of ceiling microphones focuses on discretion and functionality. The unique enclosure design effectively suppresses large space reverberation, capturing clear, undistorted, and omnidirectional sound. Installation considerations involve strategic placement to optimize sound pickup while maintaining the aesthetic integrity of the space. The ceiling mic mount plays a crucial role in this, allowing for secure and optimal positioning.

Features

Applications and Advantages

Ceiling microphones are versatile, suitable for use in multiple scenarios such as large conference halls or intimate meeting rooms. The advantage of PeopleLink microphones with ceiling installation is their wide coverage and the elimination of table clutter, common in traditional conferencing setups. Systems like DSP CM exemplify this advantage, offering both convenience and quality.

Features

Simple to Integrate and Compatible with VC Applications

Integrating a ceiling mic into your existing audio-visual system requires careful consideration of compatibility. Products like DSP CM with hanging microphones from ceiling arrays are designed to work seamlessly with various AV interfaces and applications, ensuring that the system functions as a cohesive whole.

Features

Superior Audio Reception

The DSP CM master receiver seamlessly connects to active speakers and two suspended ceiling microphones. It supports local amplification and local sound reinforcement, making it a versatile solution for large conferences and leisure venues.

Where a Ceiling Microphone System Fits in Your Organisation

How organisations deploy a Ceiling Microphone System, and what changes for the teams that use it

Education

Classroom Audio for a University

A university fits its Lecture Classrooms with the PeopleLink DSP CM so a lecturer can teach from anywhere between 2 and 10 metres of a suspended microphone. Two spherical microphones hang from the ceiling and cover a room of 80 to 100 square metres, while the master receiver's AEC, AGC and ANS keep remote students free of echo. The receiver connects to the room PC over USB Type B and to an Active Speaker for Local Sound Reinforcement, so the class hears clearly too.

Enterprise

Training Room Audio for a Bank

A bank's learning centre runs product training for 15 to 30 staff at a time, half of them joining from branches. The PeopleLink DSP CM keeps the tables clear: two ceiling microphones with a 10 metre, 360 degree pickup radius capture the trainer and every participant, and the built-in digital audio processor mixes them intelligently before the USB feed reaches the Video Conferencing platform. A 75dB signal-to-noise ratio keeps recordings clean. With a PeopleLink Camera in the same room, branch staff see and hear the whole session.

Government

Conference Room Audio for a State Secretariat

A state secretariat's departmental Conference Room hosts review meetings with district offices several times a week. Rather than a chain of table microphones, the PeopleLink DSP CM suspends two microphones from the ceiling; each covers a 10 metre radius, so officials speak from their seats and are heard. The master receiver handles echo cancellation and noise suppression, connects to the room PC over USB and to an Active Speaker for local amplification. Minutes are clearer, and the table stays free for papers.
