Modifying and storing the effect
All effects have a number of parameters that may be modified using the front panel
controls (see page 246). The modified effect can then be stored to a user-memory
location enabling, for example, the engineer to include a wide range of echo effects (all
originally derived from the same program) from a personal library of variations.
We recommend that a safety copy is kept, see "Files screen" on page 123.
To store the modified effect, press ST on the front panel.
Direct signal
Effects such as 'ADT' and 'Echo' rely on a suitable level of direct (dry) signal being
added on the mixing console. Since this is largely a question of taste, no precise
instructions are included here. It is recommended that, as a general principle, direct
signal is initially set at a normal operation level without any effect present. The effect is
then increased in level as required.
"Delay" effect
PRE DELAY control knob adjusts the delay time within the range 0 to 2.0 seconds.
REV button mutes the effect.
Preset parameters: On selecting this effect program, delay is set to 200ms.
Stereo mix: The signals at left and right outputs are both delayed by the same amount
as set using the PRE DELAY control, that is, they are essentially monophonic.
Application Notes:
• Operation is self-explanatory.
• Use this program to accurately balance echo return levels on the mixing console.
• In normal use, only one output should be used.
"ADT" effect
PRE DELAY control knob adjusts the delay time before the second voice is heard.
Delay is adjustable within the range 0 to 127ms.
PATTERN control knob selects the number and spacing of the second voices. Selection
is from Pattern 1 (two voices) to Pattern 5 (eight voices).
REV button mutes the effect.
Preset parameters: On selecting this effect program, delay is set to 40ms and pattern
is Pattern 5 (a wide multi-voiced effect).
Stereo mix: Left and right output signals use different delay taps to achieve a stereo
effect. Using only one output halves the number of 'voices', that is, Pattern 1 (one
voice) to Pattern 5 (four voices).
Application Notes:
• Try delays from 25 to 50ms. Short delays reduce the effect, long delays produce
echo.
• Direct signal must be added at a suitable level on the mixing console. Try 50/50
direct/effect mix on Pattern 1, must less direct on Pattern 5.
