5) 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, thus the amount of DSP
resources allocated to 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 depends on the 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. Speaker delay is typically used when
aligning speaker drivers or other locations where only a short delay is required. This
leaves more DSP processing available for other functions.
Parameters
Delay - Amount of delay added to the signal (displayed in milliseconds,
feet, or meters).
Temperature - Local temperature, used to calculate the speed of sound
though air and thus the distance corresponding to the delay time.
Link Group - The link group to which the delay's parameters will be linked.
Show Detailed Channel Information - If both delay functions are used
on the same channel, all parameters can be viewed in a single window.
6) Metering
The audio meter 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
bandwidth-limited 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.
