The DBX 520 is an outstanding analog de - esser designed to tackle excessive sibilance in vocals and high - frequency dense audio materials. Inspired by the classic dbx 902, it can precisely control de - essing regardless of signal level variations. With its modular 500 Series design, it analyzes the dB differences between high - frequency and full - bandwidth signal parts, enabling de - essing of signals with up to 60dB level changes. It offers a Frequency Control ranging from 800Hz to 8kHz, Expanded Scale LED Gain Reduction Metering, and a De - essing Amount Range from 0dB to 20dB. This means you can create clear, sibilance - free vocals effortlessly. Key features include being based on the dbx 902, a wide frequency control range, advanced metering, a flexible de - essing range, In/Out and HF Mode switches. Technical specs cover input/output types, impedance, levels, frequency response, noise, and more, making it a reliable choice for audio professionals.
Using the DBX 520 is quite easy. First, connect it to your audio system according to the input and output specifications. You can adjust the Frequency Control to set the frequency range from 800Hz to 8kHz where you want to reduce sibilance. The In/Out switch allows you to quickly turn the de - essing function on or off. The HF Mode switch gives you an option for high - frequency only de - essing. Keep an eye on the Gain Reduction Metering to see how much reduction is happening. When using it, make sure the power supply meets the requirements of +/- 16V DC. Avoid exposing it to extreme temperatures or humidity. For maintenance, just keep it clean and free from dust. If you have any problems, check the connections first. If the issue persists, consult a professional.
