5) Delay
Speaker Delay and Delay
Both the Speaker Delay and Delay allow the signal to be delayed by a
given number of samples (a given amount of time). The only differences between
the Speaker Delay and Delay is the total amount of delay available and the amount
of DSP resources used by each block. The Speaker Delay uses far less DSP resources
than the Delay and should be used first, whenever possible. Note that the total amount
of delay available from each block will vary with sampling rate. For convenience,
if both the standard and extra delay are used, parameters for both can be displayed
simultaneously on a single control screen.
For linking purposes, Speaker Delays are linked only to other Speaker
Delays, and Delays are linked only to other Delays. Typically the Speaker Delay is
useful when aligning speaker drivers or other locations where only a short delay is
required. This leaves processing available for other functions.
Parameters
Delay
- Amount of delay added to the signal (presented in milliseconds,
feet, or meters).
Temperature
- Local temperature, used to calculate the speed of sound
though air and thus the distance orresponding to the delay time.
Link Group -
The link group to which the delay's parameters will be linked.

If both Base and Extra Delay are
used, this allows all parameters to be viewed in a single window.
6) Metering
The Audio Meter does not affect the audio signal. It allows the signal to be monitored
at any location in the signal chain. Display range is -60dBu to +20dBu.
7) Signal Generator
The Signal Generator creates its own Pink Noise, White Noise or Sine Wave output, replacing
any audio signal in the chain before it. When bypassed, the Signal Generator allows the input signal to pass to
the output of the block unaffected. White Noise is randomly generated broadband noise, while Pink Noise is
band-limited to 20Hz - 20kHz to contain equal energy in any octave (-6 dB per octave low-pass filtered). The
Sine Wave has adjustable frequency. These signals may be generated at any level from -50dBu to +20dBu.
Parameters
Mode
- The type of signal to be generated (Pink Noise, White Noise, Sine Wave)
Frequency
- Frequency of signal to be generated (sine wave only).
Level -
RMS level of signal generated.
Bypass -
Turns off generated signal, and allows input to be passed through to output unaffected.
