Early or Reflection Delays. In many real spaces, distinct reflections and echoes are an
important part of the sound, so many of the 960L's reverbs have reflection delay and echo
paths with appropriate controls.
The Early or Reflection Delays set the delay time. For example, dLF>RS is the delay time in
a path from the Left Front Input, through the diffusor, through a delay of dLF>RS duration,
and finally to the Right Surround Output.
Each of these delay paths has its own level control. The level of the example delay path is set
by the related control LvLF>RS.
Echo Duration. Some reflection delays have echo capabilities. These appear as part of the
input path; echoes are passed to the reverberators as well as the reflection outputs. Also,
echo signal is fed back through the input diffusors. This means that each echo will be more
diffuse and spread than its predecessor. The control EchoLS sets the duration of an echo
(that is, a feedback path) on the Left Surround Input and FbckLS sets the amount of feedback
for that path. Any echo pattern set with EchoLS and FbckLS will be heard in the surround
reverb field and also in any reflection delay whose source is the Left Surround Input.
Echo Master Delay multiplies all echo delays by a percentage. This allows this single control
to scale a complicated echo pattern.
Early Master Delay multiplies all reflection delays by a percentage. For example, if Left
Surround Delay is set to 24 msec and EDlyMST is at 50%, the actual Left Surround Delay
time will be 12 msec and that figure will appear on the display. This allows this single control
to scale a complicated reflection pattern.
Early Level Master Control Multiplies all individually selected early reflection levels by a
percentage. This allows this single control to set the overall level of a complicated reflection
pattern.
Early Rolloff controls the cutoff frequency of a 6dB per octave low pass filter on the output of
the early reflections.
