+ 0 - THRESHOLD leds:

The Ò+Ó led illuminates when the signal is above the OverEasy¨ portion of the compression curve and that the full compression ratio is in effect . If OverEasy¨ is disabled, this led indicates that the signal is above the level set by the Compressor Threshold control and that compression is occuring.

The Ò0Ó led illuminates when the signal is in the OverEasy¨ portion of the compression curve. In this region the ratio varies as a function of signal level between 1:1 and the ratio set by the Ratio control. This led will not light when the OverEasy¨ function is off.

The Ò-Óled illuminates when the signal is below the level set by the Compressor Threshold control. This indicates that the Compressor is not compressing and is operating in its linear region.

THRESHOLD control:

This control sets the level above which compression occurs, and has a 60 dB range.

OverEasy¨ switch:

OverEasy¨ is a feature that provides a softer compression sound than hard knee does. OverEasy¨ smooths the transition from un-compressed to compressed. This smooth transition greatly reduces compression artifacts and allows faster attack times and higher compression ratios while still main- taining the natural characteristics of the signal. The switch lights to indicate OverEasy¨ processing is enabled. When conventional hard knee processing is desired, disable the OverEasy¨ function. See Figure 3 for a comparison of OverEasy¨ and hard knee compression curves.

The unit includes a powerful parametric equalizer with multiple frequency bands, enabling precise tonal adjustments. Users can easily tailor their sound to fit various musical styles or venue acoustics, enhancing overall audio clarity.

The dbx Pro 566 also integrates a high-performance compressor that provides dynamic control over audio signals. Its flexible threshold, ratio, attack, and release settings allow for fine-tuning of compression characteristics, ensuring that the audio maintains its natural dynamics while preventing clipping or distortion. This feature is particularly useful in live sound situations where maintaining consistent audio levels is crucial.

Another technology that sets the dbx Pro 566 apart is its built-in de-esser. This dedicated circuit is designed to reduce harsh sibilance in vocal recordings, providing a smoother and more balanced sound. This is essential for vocal performances where clarity is vital, allowing for a more pleasant listening experience.

The dbx Pro 566 also boasts comprehensive metering options, including LED meters for visual feedback on levels and gain reduction. These indicators help users monitor their audio signals effectively, facilitating quick adjustments when necessary. The unit's user-friendly interface ensures that sound engineers can navigate its features without hassle, making it accessible for both beginners and experienced professionals.

In terms of connectivity, the dbx Pro 566 features standard XLR inputs and outputs, ensuring compatibility with a broad range of audio equipment. Its robust build quality and reliability make it suitable for both studio and on-the-road applications, providing longevity in demanding environments.

Overall, the dbx Pro 566 is a powerful audio processor that delivers essential features and advanced technologies needed for modern audio production. Its combination of equalization, compression, and de-essing capabilities makes it an invaluable tool for achieving high-quality sound in various settings. Whether for live performances or studio recordings, the dbx Pro 566 stands out as a top choice for audio professionals.
