DBX 166XL 2 Channel Compressor Limiter Gate The dbx 166XL provides two channels of noise gating, OverEasy or classic hard knee compression and PeakStop limiting to give complete control of signal dynamics to studios, sound reinforcement companies, musicians, or anyone who needs quality processing quickly and easily. We recommend that you take a moment and read through the manual as it provides information that will assist you in using your unit to its fullest potential.
When using the 166XL’s Attack and Release controls, artists and engineers will find that the center settings deliver classic dbx compression, while the full control range produces voicings that extend from slow leveling to aggressive peak limiting.The 166XL’s advanced gate circuitry uses a completely new, program-dependent timing algorithm to produce ultra-smooth release characteristics—even with complex signals, such as voice or reverb decays. dbx engineers went on to take advantage of the wide dynamic range and high precision of the dbx V1 VCA to design in an extra-wide threshold range and ensure top gating performance for each application.
FEATURES
- Goof proof operation to smooth uneven levels, add sustain to guitars, fatten drums or tighten up mixes.
- New gate timing algorithms ensure the smoothest release characteristics.
- Program-adaptive expander/gates.
- Great sounding dynamics control for any type of program material
- Separate precision LED displays for gain reduction, compression threshold and gate threshold allow quick, accurate setup.
- Stereo or dual-mono operation.
- Balanced inputs and outputs on 1/4 inch TRS and XLR.
- Side Chain insert.
- Classic dbx Auto mode.
Separate precision LED displays for gain reduction, compression threshold and gate threshold allow quick, accurate setup, while the 166XL’s intuitive operation lets users easily smooth uneven levels, add sustain to guitars, squash drums or tighten up mixes. In Stereo couple mode, the Channel 1 controls become Master controls, and Channel 2 follows precisely to ensure a rock solid stereo image—even with high amounts of compression, through True RMS Power Summing. Professionals and newcomers alike will find that the 166XL sets up rapidly and musically the first time it is used, especially with the Auto attack and release function. Advanced applications are now easy, with the 166XL’s full sidechain functionality, and the ability to use either hard knee or OverEasy compression algorithms. Add to this already impressive list of features the venerable PeakStop limiter, and you’ve got a strong finisher, every time.
The dbx 166XL processor is the result of an intensive engineering and product development effort aimed at taking advantage of the latest and best advances in manufacturing technology to deliver true dbx audio performance and reliability to our customers at the lowest possible cost. The 166XL puts a completely new level of compressor/gate performance within everyone’s reach.
