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.
• For conventional ADT, try ‘Delay’ of 40ms, Pattern 1, and use one output only,
panned, say, fully right. Pan direct signal fully left and use a 50/50 direct/effect mix.
“Multi-Tap Echo” effect
PRE DELAY control knob adjusts the time delay interval between the direct signal and
the first repeat. Delay is adjustable from 0 to 990ms.
PATTERN control knob selects the number and spacing of the repeats. Pattern 1 (two
repeats) to Pattern 9 (eight repeats).
DECAY control knob sets the feedback (regeneration) level for repeat echoes.
HF control knob allows the high frequency filtering to be applied to the regenerated
signal.
REV button mutes the effect.
Preset parameters: On selecting this effect program: delay is set to 196ms; pattern is
Pattern 4; decay is 73; and HF is 0. These settings give an effect similar to a typical
multi-head tape echo, but with full stereo image.
Stereo mix: Different delay taps are used for left and right outputs to achieve a stereo
effect. Using only one output halves the number of taps, that is, Pattern 1 (one tap),
Pattern 9 (four taps).
Application Notes:
• Set delay time as required, generally fairly short for multi-echoes (higher pattern
numbers), and longer for repeat echo. ‘Fine tune’ delay setting to set exact musical
timing for single tap repeat echoes.
• Direct signal must be added at a suitable level on the mixing console.
• For single tap repeat echo, start with Pattern 1, with ‘Delay’, ‘HF’ and ‘Decay’ all set
at maximum. Reduce parameters as required. Use one output only.
“Sound-On-Sound” effect
PRE DELAY control knob sets the ‘loop length’ and hence the timing of the effect
between 0 and 2.0 seconds.
LEVEL control knob provides 10 level increments of signal input to the ‘digital loop’.
Return level to ‘0’ after use to avoid noise build-up.
DECAY control knob sets the ‘erasure’ of the loop from ‘0’ (100% erasure) to ‘99’ (zero
erasure).
REV button clears memory of unwanted effect.
Preset parameters: On selecting this effect program: pre-delay is set to 2.0s; level
is 0; and decay is 99. These settings represent maximum loop length with zero
erasure. Please note that no sound will be heard until ‘level’ is increased.
Stereo mix: Outputs left and right are essentially identical. However, to avoid the
possibility of slight phase cancellations, it is recommended that only one output is used
on this program.
Application Notes:
• Since the ‘level’ inside the signal processor increases as fresh input is added, input
level must be lower than that recommended for normal use; try -15dB on the
