Operation
Limiter
To achieve the desired results with the integrated limiter, it is important to understand its operation. The threshold value is fixed at 20 dBu. The clean and/or tube gain settings determine the amount of limiting, so that these settings more or less work like a threshold control. When the limiter is activated, it levels everything above 20 dBu. The orange 18 dB LED, which displays this level range, varies in brightness depending on limiting. The actual amount of limiting is displayed by the Limit LED, which becomes brighter as more level reduction is applied.
The peak limiter sounds different with the tube stage activated, since leveling occurs somewhat asymmetrically with the tube in the signal path, so that the negative
To determine the ideal limiter setting for the internal converter, activate the peak limiting mode and adjust the Clean and/or Tube Gain to a setting well above your working level, so that the Limit LED illuminates brightly. Then reduce the Output Level until the AD OVL LED goes out. Now your gain levels can be returned to their normal settings and the limiter can be switched into FET mode if desired. The same method should be used with an external converter, except that in this case the external unit‘s clip LED is used for calibration. If you are only using the FET limiter and your program material contains few fast transients, the output level can be set somewhat higher.
