AutoVelocity™ Dynamics and the dbx 160SL

adjusted too fast for a particular application. In fact, most users find that they use only the upper half (12:00 and clockwise) of both the attack and release controls for 99% of their compression needs. Inappropriately fast attack and release times can “chew up”a signal yielding unpleasant results. This is why we have chosen to limit the range of the attack and release controls on other compressors we manufacture such as the 1066.

The ultra-fast response of the 165/165A is one reason for its longevity and “classic” status in the pro audio arena, enabling it to dynamically alter fast signals as well as provide a creative tool for intentionally shredding the sound, adding “bite” to vocals, for example. To preserve the heritage of the 165/165A, we chose to include its manual attack and release characteristics in the new Blue Series 160S. But in striving to constantly improve our products,we sought a way to combine the benefits of having ultra-fast response to fast signals with the forgiving program-dependent characteristics of the Auto mode. Enter AutoVelocity™ Dynamics processing (AVD). AutoVelocity™ Dynamics circuitry allows the engineer to set the attack and release controls for relativity fast settings and not have the dynamic distortion problems associated with these faster settings.

The AutoVelocity™ Dynamics circuitry allows the compressor to operate in a manually adjustable program-dependent mode, meaning signals that change slowly experience slower attack and release times than what are indicated by the attack and release controls; see Figures 1 and 2. For signals that change quickly (i.e. snare drum hit), the attack and release response speeds up to reflect the actual settings of the attack and release controls; see Figures 3 and

4.The faster attack time allows us to catch the transients without allowing overshoot and to release quickly from the larger change of compression without “punching holes” in our sound. So, we get to use the full range of the attack and release controls without being overly cautious of setting the controls

AUTOVELOCITY DYNAMICS AND THE DBX 160SL specifications

The dbx Pro Autovelocity Dynamics system, particularly known for its incorporation in the dbx 160SL compressor/limiter, represents a significant advancement in audio processing technology. The dbx 160SL is renowned for its ability to provide transparent dynamics control that enhances audio recordings while preserving the natural characteristics of the sound.

A standout feature of the dbx 160SL is its patented Autovelocity technology. This innovative approach allows for real-time adjustments to the threshold and ratio based on the incoming audio signal’s dynamics, providing musicians and audio engineers with unparalleled control over their sound. The result is a compression effect that responds naturally, ensuring that softer sounds are brought up without squashing the peaks, maintaining clarity and punch in the mix.

Another critical aspect of the 160SL is its comprehensive metering capabilities. Users can monitor gain reduction and input/output levels through precise LED meters that provide quick visual feedback. This feature is vital during live performances and studio sessions, as it allows for immediate adjustments to maintain optimal audio quality.

The dbx 160SL features selectable attack and release times that cater to different musical genres and preferences. Additionally, the compressor supports a range of sidechain filtering options, enabling users to emphasize or de-emphasize certain frequency ranges in the compression process. This is particularly beneficial for bass-heavy tracks or vocal recordings, where clarity is essential.

Built with durability in mind, the dbx 160SL features a robust chassis that stands up to the rigors of both studio and live environments. Its user-friendly interface makes it accessible for both novices and seasoned professionals, ensuring that anyone can achieve high-quality sound with minimal effort.

Furthermore, the 160SL's legendary dbx sound is attributed to its brilliant signal path design, which employs high-quality components that ensure low noise and high performance. The versatility of the dbx 160SL makes it a staple in both analog and digital recording setups, cementing its status as an industry-standard tool for dynamics processing.

In conclusion, the dbx Pro Autovelocity Dynamics and the dbx 160SL represent a powerful combination of innovative technology and classic audio processing techniques. Their features not only enhance audio quality but also streamline the recording and mixing process, making it easier to achieve professional sound results. With its reputation for excellence, the dbx 160SL continues to be a trusted choice for audio professionals around the world.
