Large meeting spaces

A brief guide to audio in higher education

Large meeting spaces are vital to higher-education institutions that want better communication and collaboration in faculty meetings and seminars. With the growing popularity of distance learning, and with many faculty accessing meetings remotely, high-quality audio conferencing technology is a must. Learn how the leading approaches to audio conferencing for large meeting spaces stack up when it comes to pickup, aesthetics, installation, price and more.

Option A: Multicomponent systems

May include: Podium or lapel mic for the instructor/chair, ceiling mic arrays or distributed tabletop mics for seated participants, hanging mics for participants away from the table, amplifier, DSP, mixing board, cables and speakers. Requires UC&C-equipped computer.

Audio pickup

The green circles show approximate voice pickup zones when omnidirectional tabletop mics and a podium mic are used. It could be difficult for remote participants to hear in-room participants outside the circles – whether seated away from the table or moving about the space to work at displays.

Pickup

Instructor: The most common methods are a separate podium or lapel microphone. Student: A common solution is multiple desktop omnidirectional microphones. Other strategies may include one or more in-ceiling beamforming mic arrays or hanging omnidirectional mics.

Installation

Installing a multicomponent system may entail a range of procedures ranging from creating pathways for cables for desktop and podium mics to installing in-ceiling mic arrays. Installation may require skilled technicians and make the room unavailable for a day or more.

Aesthetics

Installed in-ceiling systems, including microphone arrays and external speakers, are unobtrusive and can bring a polished, premium look (with a price to match). Distributed omnidirectional microphones and cables can cause clutter and potential hazards on tabletops and floors.

Calibration and mixing

Calibration can be a challenge. Getting the levels right so the chair and other participants are balanced and can be heard by remote participants may require a technician and/or real-time mixing of levels (input and output). Reconfiguring the room will likely require recalibration.

Performance

A properly calibrated system can provide professional grade performance. This can be diminished if participants move away from the pickup zones. Accommodating dynamic lessons (where participants move and work at displays) may require reinstallation of the hardware.

Value

Prices for hardware and installation of traditional multicomponent systems vary widely, but they can be as high as tens of thousands of dollars. Institutions choosing this option should be sure to budget for ongoing maintenance and calibration (many providers offer service plans).

Option B: Virtual microphone system

Includes: Two wall-mounted integrated microphone and speaker bars, cables and connect module connected to a UC&C-equipped computer.

Audio pickup

The HDL300 system employing virtual microphones provides true full-room pickup. In-room participants can be heard by remote participants from anywhere in the room.

Virtual microphone scorecard

Pickup

There is no need for external microphones for the instructor or students. The Dual HDL300 system’s virtual microphones provide true full-room pickup throughout spaces up to 30' x 50' (9.14 x 15.24 m).

Installation

The Dual HDL300 system’s two integrated microphone and speaker bars can be installed on the wall in less than 60 minutes. Installation is minimally invasive and no specialized technicians are required.

Aesthetics

The two 60" x 5.9" (152.4 x 15 cm) wall-mounted units are sleek and unobtrusive. They are available in black or white to suit virtually any decor. There is no need for external microphones, speakers or cabling.

Calibration and mixing

Calibration is automatic for any room configuration or meeting style. Nureva Room Manager enables adjustment of audio levels and integration with external speakers. It also upgrades the system through automatic firmware updates.

Performance

Provides professional grade performance. Thanks to its Microphone Mist™ technology, the Dual HDL300 enables true full-room pickup that may exceed the coverage of traditional systems, allowing for more dynamic meetings.

Value

The hardware cost for the Dual HDL300 system is a fraction of most multicomponent systems. There are also significant savings on installation and setup as the system can be easily installed by in-house personnel, and calibration is automatic.
