The case above is taken for simplicity, obviously the S-DMX is far more flexible than the
example shows; the example is only used as a guide to the techniques involved.
Mixing
When using the S-DMX alone, mixing of the two delayed channels can be accomplished
by use of the output mix control on the front panel of the unit. A much larger variety of
effects are attainable when using the S-DMX in conjunction with a mixing desk since the
original signal may also be mixed with the outputs of the delay lines.
ADT
Automatic Double Tracking is improved if the secondary signal is varied in pitch by a
small amount. This can be accomplished by adjustment of the vco controls or by
incorporation of the pitch change option.
When using the vco section to improve ADT remember that the pitch variation is
dependent upon both the vco speed and depth control settings, and also the delay times
between the original signal and the outputs of the unit. To obtain this improved ADT
effect first switch the ‘xtal./vco’ switch to vco. For an ADT setting of 18mS the best effect is
obtained by setting the depth control to ‘9’ and the speed control between ‘2’ and ‘3’; as
the delay setting is increased however, the depth setting will have to be decreased to
retain a reasonable ADT effect.
VCO
The vibrato effect created by the vco can if used properly, enhance the effect of certain
instruments and is a useful tool in its own right.
Controlled Flanging
The following method can be used if flanging is required using the S-DMX outputs alone.
First return all the front panel controls to their ‘original’ settings. Now switch the ‘out
sep./mix’ control to mix; if now the nudge buttons are used around zero delay, flanging
should be audible.
By using the mixing desk other methods can be employed to achieve flanging using the
basic principles outlined above.
The Dual Lock In Function
As mentioned in the earlier ‘Operation’ section when the ‘lock in’ switch is thrown the
word LOC will be displayed and the contents of the ‘A’ channel delay line at that instant
will be locked in.
By using the ‘lock in’ facility the loop on channel ‘a’ may be edited.
As an example we have chosen to remove 100mS from the beginning and end of a loop.
We have chosen a loop size of 1.638 Seconds and have assumed for clarity that no
previous editing has been done.
