Feedback Suppressors

feedback suppressor: Manufactures, Types, Features & Applications

Introduction

A feedback suppressor is a device used to prevent feedback in sound reinforcement systems. Feedback occurs when a sound loop is created between a microphone or an instrument and a speaker, resulting in a loud and high-pitched tone. Feedback can be a significant problem in live sound applications, and it can be difficult to control without the use of a feedback suppressor.

Feedback suppressors are commonly used in live sound reinforcement applications such as concerts, conferences, and worship services. They can be particularly useful in situations where multiple microphones are being used, or when speakers are placed close to microphones or instruments.

There are two main types of feedback suppressors: hardware-based and software-based.

Also, feedback suppressors can be connected to various audio equipment, including DI boxes, audio matrix/zone mixers, audio equalizers, audio signal processors, and amplifiers, in several ways depending on the specific equipment and application. It’s important to follow the manufacturer’s instructions and ensure that all connections are properly made to avoid any issues with feedback or other audio problems.

Overall, feedback suppressors are an essential tool for any sound engineer or musician who wants to prevent feedback and ensure high-quality sound in live sound applications.

Types

Feedback suppressors are devices that are used to eliminate or reduce feedback in sound systems. There are different types of feedback suppressors, and they can be classified based on various criteria. Here are some classifications of feedback suppressors:

1. Analog vs. Digital Feedback Suppressors: Analog feedback suppressors use hardware circuits to detect and eliminate feedback, while digital feedback suppressors use digital signal processing algorithms to achieve the same goal.

2. Single-Channel vs. Multi-Channel Feedback Suppressors: Single-channel feedback suppressors are designed to suppress feedback in one channel of a sound system, while multi-channel feedback suppressors can handle multiple channels simultaneously.

3. Tube DI Boxes: These are active DI boxes that use vacuum tubes to amplify and color the sound. Tube DI boxes are prized for their warmth and character and are often used in recording studios to add a vintage or classic sound to recordings.
   

4. Parametric vs. Graphic Feedback Suppressors: Parametric feedback suppressors use parametric equalizers to adjust the frequency response of a sound system, while graphic feedback suppressors use fixed frequency bands to achieve the same goal.
   

5. Automatic vs. Manual Feedback Suppressors: Automatic feedback suppressors use algorithms to detect and eliminate feedback automatically, while manual feedback suppressors require the user to adjust the settings manually to suppress feedback.
   

6. Hardware vs. Software Feedback Suppressors: Hardware feedback suppressors are standalone devices that are typically placed in a sound system signal chain, while software feedback suppressors are computer programs that can be used with digital audio workstations or other software-based sound systems.
   

These are just a few examples of how feedback suppressors can be classified. The type of feedback suppressor that is best for a particular sound system will depend on various factors, such as the size and complexity of the system, the type of music or sound being produced, and the level of control required by the user.

History

Feedback suppressors have been in use since the early days of sound reinforcement systems when feedback was a common and frustrating problem. The first feedback suppressors were simple notch filters that were manually adjusted by sound engineers to eliminate feedback frequencies.

In the 1960s, automatic feedback suppressors were developed that used analog filters and audio detectors to automatically adjust the notch filters and prevent feedback. These early feedback suppressors were effective, but they were also complex and expensive, and they required a high level of expertise to use.

In the 1980s, digital signal processing (DSP) technology began to revolutionize the audio industry, and feedback suppressors were among the first applications of this technology. Digital feedback suppressors were able to offer more precise and effective feedback elimination, as well as more flexible and user-friendly controls.

Today, feedback suppressors are widely used in live sound applications, and they are available in a variety of hardware and software formats. Modern feedback suppressors can be very precise and effective, using advanced algorithms and filters to identify and eliminate feedback frequencies in real-time.

Overall, the development of feedback suppressors has been driven by the need to eliminate feedback and improve sound quality in live sound reinforcement systems. While the technology has evolved, the basic goal of preventing feedback remains the same, and feedback suppressors continue to be an important tool for sound engineers and musicians.

Why is feedback suppression important in event technology?
Feedback can disrupt sound quality, cause unpleasant noise, and even damage equipment if left unchecked. Feedback suppressors ensure clear and stable audio output, enhancing the overall experience for event attendees.

What types of events can benefit from using feedback suppressors?
Feedback suppressors are beneficial for various events, including concerts, conferences, live performances, presentations, weddings, and any other occasion where audio amplification is required.

How do I choose the right feedback suppressor for my event setup?
Consider factors such as the size of the venue, number of microphones and speakers, desired features (e.g., automatic vs. manual control), and budget when selecting a feedback suppressor. Consult with audio professionals for personalized recommendations.
Can feedback suppressors eliminate feedback?
While feedback suppressors can significantly reduce feedback, complete elimination may not always be achievable, especially in challenging acoustic environments. Proper setup, sound system design, and microphone placement are also essential factors in minimizing feedback.

Are feedback suppressors easy to set up and use?
Many feedback suppressors offer user-friendly interfaces and automatic setup features, making them relatively easy to install and operate. However, some models may require more advanced knowledge for optimal configuration.

Do feedback suppressors affect sound quality or alter the original audio signal?
High-quality feedback suppressors are designed to minimize interference with the original audio signal, preserving sound quality. However, improper use or excessive filtering may result in subtle changes to the audio, so it’s essential to adjust settings carefully.

Can feedback suppressors be used in conjunction with other audio processing equipment?
Yes, feedback suppressors can be integrated into complex audio setups alongside mixers, equalizers, and other processing devices. Compatibility and signal routing should be considered when configuring such systems.

Are there any limitations or drawbacks to using feedback suppressors?
While effective in reducing feedback, feedback suppressors may occasionally mistake desired audio signals for feedback, leading to unintended filtering. Additionally, they may not address underlying issues such as poor microphone technique or acoustically challenging environments.

How can I troubleshoot feedback issues when using a feedback suppressor during an event?
If feedback persists despite using a suppressor, try adjusting microphone placement, speaker positioning, or room acoustics. Additionally, fine-tuning suppressor settings or manually adjusting filters may help resolve stubborn feedback problems. If issues persist, consult with audio professionals for further assistance.

How do I choose the right feedback suppressor for my sound system?
When choosing a feedback suppressor, consider the specific features and capabilities that you need, as well as the size and type of your sound system. It is also important to choose a reputable manufacturer with a history of producing high-quality audio equipment.
