Attention Points for Installation of Conference Room Sound System

 Conference Room Sound System Equipment Types

When selecting and installing conference room sound systems, it is important to understand the different types of audio equipment to meet the needs of different sizes and requirements of conference rooms. Here are some common audio devices:

 

Column Speakers

Suitable for large conference rooms, with high fidelity and strong sound-absorbing performance, effectively suppressing echoes and interference.

 

Conference room ceiling speakers

Widely used in medium and small conference rooms, installed on the ceiling, lightweight and stylish, suitable for limited floor space.

 

Wireless Microphones

No need for cable connections, suitable for temporary conference rooms or scenarios where speakers need to be moved, easy to operate and portable.

 

Mixing Console

The core component of the sound system, responsible for adjusting, mixing, and amplifying audio signals, with multiple input channels and rich sound effects adjustment functions.

 

Loudspeakers

Convert the audio signals output by the mixing console into sound, with two types of active speakers and passive speakers, power related to speaker aperture.

 

Conference Room Sound System Equipment Connection Sequence

When installing audio equipment, the correct connection sequence is crucial to ensure the system operates smoothly. Here are the basic connection steps:

 

Connecting Speakers

First, connect the column speakers or ceiling speakers to the mixing console via audio cables, then connect the output signal of the mixing console to the speakers via optical fiber or RCA cables.

 

Wireless Microphone Connection

Connect the wireless microphone to the mixing console via wireless signals, then connect the output signal of the mixing console to the speakers via wired connection.

 

Ceiling Speaker Network Connection

Install the ceiling speakers on the ceiling using network cables, connect them to the controller via the network, and then output the audio signal to the ceiling speakers through the controller.

 

Conference Room Sound System Design

Designing a reasonable sound system is crucial for the sound effect in conference rooms. Here are some suggestions:

 

Choose Configuration Based on Size

Select appropriate audio equipment configuration schemes based on the size and usage requirements of the conference room. The larger the area, the higher the power needed for audio equipment.

 

Use Dispersed Audio Equipment

To ensure even sound distribution, it is recommended to avoid using centralized audio equipment and choose dispersed audio devices such as ceiling speakers.

 

Positioning and Angle Adjustment

 

Follow the principle of "front left, rear right" to position audio devices, ensuring the main speakers, auxiliary speakers, and surround speakers are placed reasonably to reduce sound reflections and interference.

 

Recommended Audio Equipment Based on Room Size

 

According to the size of the conference room, different configurations of audio equipment are recommended:

 

Small Conference Room (10-30 square meters)

 

A pair of ceiling speakers or column speakers

 

A pair of wireless microphones

 

If budget allows, add a set of powered speakers to improve sound quality

 

Medium Conference Room (30-100 square meters)

 

Two pairs of ceiling speakers or column speakers

 

Two pairs of wireless microphones

 

If budget allows, add a set of powered speaker groups to improve sound quality

 

Large Conference Room (100-500 square meters)

 

Three or more pairs of ceiling speakers or column speakers

 

Multiple wireless microphones

 

If budget allows, add one or more sets of powered speaker groups, set up surround sound systems and reverb systems

 

Overall, installing and adjusting conference room sound systems is a technical task that requires reasonable configuration and adjustment based on actual conditions. Hopefully, the above information will provide useful references for creating a comfortable meeting environment.
