Spec description

  • INPUT GAIN 0dB to 10dB. Adjust the gain to achieve desired amount of limiting.
  • THRESHOLD +14dBu to +22dBu. The limiter threshold is normally adjusted to just below

        (limiter) maximum peak operating level. Further adjustments should not be necessary.

        Note: This control relates to peak programme level. Do not use sine waves (steady tones) to adjust, instead use programmes.

                   You could increase the input gain to make it easier find the threshold that stops ‘overs’ and then re-adjust the gain after

                   the threshold has been set.

  • HARD This control changes the limiter character to:
    • Harder knee 
    • Shorter release time 
    • Slightly more aggressive increase of loudness

           The ‘HARD’ mode is particularly useful for percussive programmes and should be used with care for softer,

           low- to mid-frequency programmes.

  • HF THRESHOLD  Adjust this control to set the amount of high frequency limiting. The limiter setting affects this control:

                                        The HF threshold is relative to the limiter threshold as if the two controls are in series (also when the limiter is off).

  • M-S Switches the side-chain of the HF limiter to M-S mode (the actual audio-path is not affected). This function can be used to ‘zoom in’ on high frequencies in the centre of the stereo image. With this control in the M-S position, signals that are either in the centre (mono) or 180 deg. out of phase have a 6 dB lower threshold than signals that are panned extreme left or right. The M-S mode can reduce mistriggering of the HF limiter.
