Delay Component

The Delay Component is capable of up to 256 Channels and 512 Taps. For each Channel, there are nTaps. For example, if you selected 100 Channels and 5 Taps, the result would be 5 Taps per Channel, or 500 total Taps.

The Delay introduces a delay in the audio signal in order to compensate for the placement of speakers. You can Bypass, Mute, Invert and control the Gain for all Taps/Channels. For the individual Taps and associated Channels, you have the same controls provided at the Master, with the addition of a control for the Delay time. You can control overall maximum delay for all Taps in the Component Properties.

There are three Delay types available in Q-SYS Designer: Standard Delay, Fractional Delay, and Crossfaded Delay. You can select which type of Delay you want to use from the Delay Properties. When you select the type of Delay, the name of the component in the Schematic changes to the appropriate Delay type.

• Standard Delay
  • Rounds the Delay time to the nearest whole number of samples
  • Ramps the signal level down to -20 dB then ramps back to the original signal level but at the new delay time
  • Use the Standard Delay if a level dip during delay changes is acceptable. This Delay uses the least Signal Processing resources.
• Crossfaded Delay
  • Rounds the Delay time to the nearest whole number of samples
  • Maintains two delay lines for each tap. When the Delay time changes, one of the delay lines is updated with the new delay time, the other uses the original delay time. The output signal changes to the new time by fading from the original Delay time completely to the new Delay time.
  • Use the Crossfaded Delay if the aforementioned level dip is unacceptable. This Delay uses a medium amount of Signal Processing resources.
• Fractional Delay
  • Interpolates the audio signal between samples if the Delay time is not equal to a whole number of samples
  • Ramps the Delay time to the new Delay time, the signal level is not changed
  • Use the Fractional Delay if you need sub-sample delay resolution. This Delay uses the most Signal Processing resources.

Inputs

Up to 256 channels of audio.

Outputs

There is a minimum of one audio-delay Tap for each Input Channel, a maximum of 512 Taps per Input Channel. The outputs. on the component, are arranged by Tap then Channel. For example Tap 1 Channel 1, Tap 2 Channel 1.
