  • Page 60: Advanced Feedback Suppression (Afs ) Insert

    ) Insert ® The DriveRack 4800/4820 offers the exclusive dbx Advanced Feedback Suppression (AFS) feedback elimination module as an Insert processing function on the Input channels. This feedback suppression algorithm reduces feedback by first finding the location of a feedback frequency and then placing a very sharp notch filter at the exact frequency that is feeding back.
  • Page 61 DriveRack ® Section 6 Detailed Parameters type switch The Type switch toggles the AFS function between different sensitivities and filter Q settings corresponding to the type of application. The different Types are Speech (Highest Sensitivity, Bandwidth = 1/5 octave and Q=7.25), Music Low (High Sensitivity, Bandwidth = 1/10 octave and Q=14.5), Music Medium (Medium Sensitivity, Bandwidth = 1/20 octave and Q=29), and Music High (Lowest Sensitivity, Bandwidth = 1/80 octave and Q=116).

For most applica- tions a Window of +/- 2 or 3 dB maintains the signal adequately. attack fader The Attack fader adjusts how fast the AGC will increase gain after the signal drops below the Target.

  • Page 64: Autowarmth Insert

    DriveRack Section 6 ® Detailed Parameters 6.13 - autoWarmth Insert ® The Fletcher-Munson Equal-Loudness curves show that the perception of low frequency signals decreases quickly with decreasing volume. The DriveRack 4800 and 4820 offer the AutoWarmth Insert module on ® each output (Insert 1) to compensate for this perceived loss in low frequencies.

  • Page 65: Compressor Insert

    This switch turns the Compressor module on and off. overeasy fader OverEasy is a characteristic of dbx Compressors and is essentially a “soft-knee” function that occurs at about the compression threshold. On analog dbx Compressors, OverEasy could only be turned on or off, but in the digital domain this parameter can have a range.
  • Page 66 DriveRack Section 6 ® Detailed Parameters auto on/off switch Auto mode dynamically sets the Attack, Hold, and Release parameters in real time, based on the incoming signal. This switch turns the Auto mode on and off. attack fader The Attack parameter sets how quickly the compressor starts to compress the signal after it passes the threshold.

  • Page 68: Noise Gate

    DriveRack Section 6 ® Detailed Parameters 6.16 - noise Gate The DriveRack 4800 and 4820 provide a Noise Gate Insert that can be placed in both the Input and/or the Output section. A Noise Gate is used to remove unwanted low-level noise in a system. The basic premise behind a Noise Gate is that gain reduction or Gating will be applied to the channel unless there is a signal that is above some Threshold.

  • Page 69: Limiter Insert

    This turns the Limiter module on and off. overeasy fader OverEasy is a characteristic of dbx Compressor/Limiters is essentially a “soft-knee” function that occurs about the threshold. On analog devices, OverEasy can only be turned on or off, but in the digital domain this parameter can have a range.
  • Page 70 DriveRack Section 6 ® Detailed Parameters attack fader The Attack parameter sets how quickly the Limiter starts to reduce the gain of the signal after it passes the Threshold. The Attack can range between 0.1 mSec and 200 mSec. The Attack time is dynamically set while in Auto mode.

  • Page 71: Notch Filter Insert

    DriveRack ® Section 6 Detailed Parameters 6.18 - notch filter Insert The 4800 and 4820 units offer 6-Band Notch Filter that can be inserted in the Input section.
