With over four decades of experience as one of the leading AV integrators in India, Actis has often received calls from companies that have had their office sound system installed by someone complaining about the sound quality.

In most cases, the sound output is not as expected by the client. In most situations, it was either a poor integration job or it was improper usage by the client. Either way, poor sound reinforcement in a professional AV application is a strict no. If you are finding that your sound quality is not crystal clear, here are some tips from Actis on getting the most of out your speaker and sound system

Proper speaker placement

Proper speaker placement is professional AV integration that is critical to get the best sound from your speakers. Keep in mind the room size, occupancy, seating position of the audience, visual interference, toeing in and speaker location among others.

Reduce interference

Low impedance, balanced microphones, and systems are more resistant to interference from outside sources such as RF signals and electromagnetic frequencies. Using shielded cables for equipment connections can reduce the seepage of other sounds through your system. Sometimes reducing the length of a cable can also help reduce interference from outside sources. Additionally, you can use a premium-grade to avoid RF interference issues.

Watch out for wireless components

When it comes to interference, evaluating and adjusting all connected wireless components ensures reliable “noise-free” performance. These devices are routinely exposed to the world around them from an RF standpoint. Most wireless units are frequency-agile meaning that the communication channel can be changed if required.

Ensure clean power sources and grounding

Ideally, the outlets that supply power to your sound equipment should have their own dedicated ground. While some systems are relatively simple, any system can be ruined with a problematic cable or connector. All interfacing components must not be electronically and mechanically evaluated on a regular basis.

Manage equalization and amplification

The goal of equalization is to make the sound that someone hears from a speaker as close to the sound that went into the microphone. Equalization is best done with a combination of listening and live-tweaking. Through detailed calculations done by AV professionals, significant acoustic challenges can be resolved with equalization and amplification solutions.

Inspect the signal chain

Signal chain adjustments maximize signal to noise while adjusting for any potential cause of distortion. The primary control is the system mixer which has the daunting task of receiving signals at varying levels and applying amplification to get individual inputs to a balanced level. Most system mixers are up to the challenge, however, a misguided adjustment can lead to damages to the signal processors or the connected speakers.

Amplification related to volume

Some speakers don’t respond well to high-volumes. We find that many times when enterprises are experiencing poor sound it is because they had to turn the volume up so everyone can hear. However, the speaker no longer has clear sound at that high volume level and starts distorting. Try turning the volume down and checking the quality of the sound. If the sound quality is still poor at a lower volume, then you know you have another problem. All these tests need to be done at the ‘head-end or the equipment rack of the system where the electronic components are usually found in abundance.

These suggestions by Actis Technologies will help you look at the basics of sound system functioning. Needless to say, your first AV integration ought to be done by an experienced AV integrator or trained technician.
