dbx AFS2 - Advanced Feedback Suppression Processor with XLR/TRS Inputs/Outputs and LCD Display in Black Finish

The dbx AFS2 is a cutting-edge Advanced Feedback Suppression Processor designed to effectively manage and eliminate audio feedback in live sound environments and installations. With its sleek black finish and advanced features, the AFS2 represents the next generation of feedback control technology, building upon the successful AFS224 model to offer enhanced performance and usability.

At the core of the AFS2 is its refined AFS algorithm, which is capable of detecting and eliminating feedback more quickly and accurately than previous models. The AFS2 provides two channels of feedback suppression, which can be operated in either stereo linked mode or dual mono mode, depending on your needs. Each channel is equipped with 24 programmable filters, allowing for precise control over feedback frequencies. These filters can be configured with widths as narrow as 1/80th of an octave, ensuring effective feedback suppression without compromising the overall tonal quality of your audio system.

The AFS2 includes both Live and Fixed filter modes. Fixed filters are used to ring out the system initially, providing higher gain before feedback occurs. In contrast, Live filters offer real-time, automatic feedback suppression during performances, adapting to changing conditions dynamically. This dual mode approach ensures that you can achieve optimal feedback control in both setup and live scenarios.

One of the standout features of the AFS2 is its easy-to-read, backlit LCD display, which provides detailed information about each filter's frequency, width, and attenuation amount. The display is complemented by 24 Filter LEDs that show the status of all filters at a glance, making it easy to monitor the processor's activity and ensure everything is functioning as expected.

The AFS2 also includes a user-friendly Wizard function that guides you through the setup and ring-out process. By pressing the large red Wizard button, you can follow on-screen instructions to complete the setup, making feedback suppression straightforward and accessible even for those who may be new to the technology.

Compared to its predecessor, the AFS2 offers several key enhancements:

• Faster and more precise feedback detection and elimination
• Improved ability to differentiate between true feedback and other audio sources like flutes or keyboards, reducing false triggers
• More accurate attenuation to ensure notch filters are less deep and more transparent
• Enhanced frequency resolution for pinpoint accuracy, allowing the use of the narrowest possible filters
• Gradual lift of Live filters to safely remove filters without causing sudden feedback
• Ability to store up to 5 user presets for easy recall of preferred settings

The AFS2 features 24-bit A/D and D/A converters with 48kHz internal processing, ensuring high-quality audio performance with minimal distortion. The analog inputs and outputs are electronically balanced and include XLR and TRS connectors, offering flexibility in integration with various audio systems. The unit's dynamic range exceeds 107dB, with low total harmonic distortion plus noise (THD+N) ensuring clean audio processing.

Additional features include input signal level metering with clip indicators, a USB port for firmware updates, and an operating temperature range of 32°F to 104°F. The AFS2 is powered by a universal switch-mode power supply, accommodating 100-240VAC and consuming just 8 watts of power. The unit's dimensions are 19 x 5.88 x 1.75 inches, and it weighs 4.5 lbs, making it a compact and efficient addition to any audio setup.

In summary, the dbx AFS2 Advanced Feedback Suppression Processor offers superior feedback control, enhanced performance, and user-friendly features, making it an invaluable tool for live sound engineers, audio installers, and musicians seeking to maintain clarity and quality in their audio systems.
