With the Series 2, dbx has a clear goal: to maintain the "field" approach of its professional graphic equalizers while offering direct usability. This generation emphasizes simple ergonomics, rack-ready connectivity, and electronics touted as a significant advancement over more basic entry-level graphic equalizers.
The result is a processor that naturally fits into a modern audio chain, both for optimizing a system and ensuring reliable patching during live performances.
This equalizer is aimed at users who want to correct a sound system, tame room resonances, adjust stage monitors, or achieve a consistent curve across multiple sources. Mounted in a rack, it becomes an effective tool to "clean up" a mix, balance a pair of speakers, or fine-tune a problematic frequency range without using a computer.
In the studio, it can also serve as a corrective equalizer on subgroups, headphone/monitoring mixes, or as a simple calibration tool in a production setup combining analog gear and an audio interface.
The constant Q topology ensures consistent behavior from band to band: you adjust, listen, and validate. The choice between +/-6 dB and +/-12 dB is particularly useful depending on the context: subtle correction in installations or more assertive intervention live when a frequency dominates.
The bypass switch facilitates instant A/B comparisons and secures the signal chain when needed. The 4-segment LED indicator helps monitor output levels at a glance, useful to avoid clipping and maintain a clean gain structure in a shared rack.
The 50 Hz high-pass filter (slope 12 dB/octave) reduces vibrations, handling noise, hum, and excessive sub-bass that unnecessarily overloads the system. It is an effective ally for improving clarity and headroom, especially on monitors or compact speakers.
The 20 mm non-conductive faders promote smooth operation and better durability over time. The integrated power supply with toroidal transformer simplifies rack integration and limits constraints related to external adapters, while contributing to stable power delivery.
