Limiter
1. The Output Limiter is used primarily for taming transient peaks to keep the output signal strength below a specified level. This can help prevent damage to
loudspeakers in the event of unintended loud signals like the drop of a microphone. When Zones are Mono or Stereo, only the Main Limiter is displayed.
When a Sub is added, a separate limiter is available to tame the energy of the Sub so it doesn’t affect the Main.
2. Enable On/bypass and Active indicator.
3. Protection for the output can be adjusted with the following parameters:
• Threshold – level where the limiter starts limiting
• Knee – controls the abruptness of the limiting as audio nears the threshold
• Attack Time – how fast the limiter engages
• Hold Time – how long it stays in limit mode after peaks drop below threshold
• Release Time – how fast the limiter stops after hold time.
4. This shows a signal Main output being limited to -20dB, and the input signal is being reduced (Gain Reduction). If the gain reduction is significant,
reducing the source level will reduce the amount of Gain Reduction needed, without changing the output level at the zone. These settings can
help smooth out the limiter’s effect, so the audio sounds natural while still protecting the speakers in the system. Too much limiter will destroy the
dynamic range of music.
