A Guide to Selecting the Best dbx equalizers feedback controllers
Understanding the Core Technology: AFS vs. Standard EQ
When shopping for these controllers, the first distinction you must make is between a traditional graphic equalizer and an Advanced Feedback Suppression (AFS) system. A standard equalizer allows you to manually shape the tonal balance of your system. While useful, it is a reactive tool that requires a skilled engineer to constantly adjust. In contrast, an AFS controller is an automated, proactive device. It uses high-speed algorithms to detect the specific, narrow-band frequencies that lead to feedback loops and applies incredibly precise, narrow notches to eliminate them. If your primary goal is preventing squeals in a live setting, prioritize AFS technology. If your goal is tonal shaping, look for a hybrid device that offers both parametric control and automated suppression.
Fixed vs. Live Mode Functionality
A critical decision factor for any professional is how the device handles frequency detection. Most high-end controllers offer two distinct operational modes: Fixed and Live. 'Fixed mode' is designed for the setup phase. You run the system at high volumes, let the controller identify the 'problem frequencies' inherent to the room and microphone placement, and then lock those filters in place. 'Live mode' is the active watchdog. It stays engaged during the performance, constantly scanning for new feedback spikes caused by moving microphones or shifting performers. For touring professionals, a unit that offers seamless switching between these two modes is non-negotiable.
Number of Filters and Precision
Not all feedback controllers are created equal in terms of surgical precision. The effectiveness of a controller is often measured by the number of available 'filters' or 'notches' it can deploy simultaneously. A controller with only a few filters may struggle in acoustically difficult rooms with multiple resonant peaks. Look for devices that offer a high count of narrow-band filters. Furthermore, check the 'Q factor' or the bandwidth of these filters. You want a controller capable of extremely narrow notches. If the filter is too wide, it will strip away the musicality of your instruments, making the system sound 'hollow' or 'thin' every time it engages.
Input/Output Configuration and Signal Integrity
Before purchasing, audit your signal chain. Do you need a stereo configuration for a main PA, or are you looking for mono processing for a specific monitor wedge? Beyond the number of channels, consider the signal path. High-quality controllers should maintain a low noise floor and high headroom to ensure that the processing itself doesn't introduce distortion. Some advanced models allow you to place the controller at different points in the chain—either before the main amplifier or as part of an insert loop—which can significantly change how effectively it manages the system's gain before feedback.
Recommendation Logic
To choose the right unit, follow this logic: If you are a venue owner looking for a 'set it and forget it' solution, prioritize a unit with robust, automated Live Mode and a high number of simultaneous filters. If you are a sound engineer who wants manual control over your tonal landscape, look for a hybrid unit that combines parametric EQ with feedback suppression. For small-scale setups or mobile DJs, a compact, single-channel unit might suffice, but for any professional stage, always opt for a device that offers a high density of narrow-band notches to preserve your audio fidelity.
