Sound quality can make or break your event. A properly tuned portable PA system will deliver clear, consistent, and powerful sound. Here are some basic tips to help you avoid the most common problems:
- Feedback and distortion : Use directional microphones and feedback suppressors (from €100).
- Insufficient volume : Select an amplifier based on the size of the space (300 W for small spaces, 1000+ W for large ones).
- Poor clarity : Use equalizers and high-quality speakers (e.g. JBL , Dali ).
- Uneven sound distribution : Place the speakers properly and use delay settings.
- Weak bass : Add subwoofers (from €400).
AUTOGARSAS.LT offers a wide selection of equipment and professional consultations to help you achieve the best result . By investing in the right solutions, you will ensure impeccable sound and a memorable experience for both performers and listeners.
Common sound quality problems in portable PA systems
Users often encounter five main problems that can compromise the sound quality of an event. According to statistics from the European Audio Engineers Association in 2023, as many as 60% of portable PA system users experience feedback at least once during an event [3] . The main problems include the following aspects:
Feedback and distortion
Feedback occurs when microphones pick up sound from speakers and re-amplify it, causing an annoying hissing sound. This is usually caused by improper microphone and speaker placement , where the microphone is too close to the speaker or pointed directly at it.
Distortion occurs when amplifiers are pushed beyond their capabilities or when poor-quality equipment is used. Even high-end PA systems can suffer from this problem if the equipment is not properly adjusted [3] . As a result, the clarity of the sound is severely affected , and the listeners are unable to hear the speech or music.
Insufficient volume or lack of power
40% of users complain about insufficient volume [3] . This problem is especially relevant in larger spaces or outdoor events, where audiences further away from the speakers have difficulty hearing the performance.
Insufficient power not only results in a quiet sound, but also puts strain on performers as they try to compensate for the system's shortcomings by speaking or playing louder. This often further degrades the sound quality and causes additional distortion.
Poor sound clarity
In 35% of cases, poor audio clarity is caused by poor equalizer settings or poor quality speakers. [2] [3] So-called "muddy" sound - unclear and blended - is caused by poor quality microphones, poor equalizer settings, improper speaker placement , or electronic interference.
This problem is particularly detrimental to acoustic performances and speakers , where it is important that every word or musical detail is clearly heard.
Uneven sound distribution
Uneven sound coverage occurs when speakers are placed unevenly or not enough for the space. This results in the sound being too loud in some areas of the space and too soft in others. This creates an uncomfortable experience – some listeners can’t hear, while others feel the sound is too loud.
In smaller and medium-sized spaces, this issue can lead to some event attendees feeling isolated or missing important parts of the show.
Weak bass reproduction
Weak bass is particularly noticeable in musical performances when the PA system is unable to reproduce low frequencies properly. [2] [3] Small or low-powered speakers often fail to reproduce low frequencies effectively, resulting in music that sounds flat.
This can make the audience feel that the performance lacks energy or fullness , which detracts from the overall experience of the event. This problem is most noticeable in contemporary music events, where low frequencies are extremely important.
AUTOGARSAS.LT specialists, in cooperation with brands such as JBL, Focal and Dali, offer solutions for both small and large spaces. Below we will discuss how to properly adjust the equipment and choose the best systems to solve these problems.
Solutions to improve sound quality
To achieve professional sound quality, it is important to properly assess the problems and choose the right solutions. Below are methods and equipment to help solve the most common audio problems.
How to reduce feedback and distortion
One of the main solutions is the correct placement of microphones . Microphones should be kept 1.5-2 meters away from the speakers and pointed in the opposite direction. It is also recommended to use directional microphones , such as cardioid or supercardioid, which capture sound from only one side.
Feedback suppressors offered by AUTOGARSAS.LT are a great solution. Their prices start from 100-200 euros , and they automatically detect and suppress problem frequencies in real time. Another effective option is PA system mixers with a DSP processor , which help control feedback.
To avoid distortion, it is important to set the amplifier's power levels correctly. It is recommended to use the amplifier at no more than 80% of its power to ensure that the sound remains clean even during the most intense moments.
Increasing volume and power output
The amplifier power should be adjusted to the size of the space . For small spaces (up to 50 people), a 300–500 W system is sufficient, for medium-sized spaces (50–150 people) 500–1000 W is required, and for larger spaces, more than 1000 W is required.
AUTOGARSAS.LT offers JBL and Focal systems, which ensure high volume levels even in large spaces. The prices of PA systems of these brands range from 500 to 2000 euros and more , depending on the power and features.
It is important to ensure that the power of the amplifier and speakers are matched . An amplifier that is too weak can damage the speakers, and one that is too strong can cause distortion. Proper tuning is essential to maintaining sound quality.
Improving audio clarity
Using an equalizer allows you to fine-tune the sound to the acoustics of the room. For example, lowering the 200-400 Hz range can eliminate murkiness, while raising the 2-5 kHz range can provide better clarity.
The Dali and Yamaha speakers offered by AUTOGARSAS.LT are renowned for their accurate frequency reproduction. Full-range speakers from these brands cost 300–1000 euros per unit and guarantee natural and clear sound.
Additionally, audio processors can optimize the signal in real time, which is especially useful for speakers or acoustic concerts.
Achieving even sound distribution
Speaker placement is a key factor. Speakers should be placed at ear level or slightly higher, pointing towards the listening area. Larger spaces require multiple speakers with slightly overlapping coverage.
When using multiple speaker systems, it is necessary to set delay parameters so that the sound reaches all listeners at the same time. This is especially important in long or complexly shaped spaces.
Improving bass reproduction
To enhance bass, the most effective solution is to add subwoofers . Such speakers can increase perceived bass by as much as 40–60% [2] . AUTOGARSAS.LT offers SVS and Polk Audio subwoofers, with prices ranging from 400 to 1500 euros .
The optimal crossover frequency ensures a smooth transition between the main speakers and the subwoofer. The most suitable range is usually 80-120 Hz , depending on the technical characteristics of the main speakers.
Sometimes, if high-quality equipment with sufficient power reserve is used, it is enough to properly adjust the equalizer to enhance the low frequencies.
