Fostex 450 - Section 4 External Effects and Processing

section 4 EXTERNAL EFFECTS AND PROCESSING
The nearest thing in real life to what is commonly termed echo,
is the effect of the repeats which you hear when you shout in
the midst of a mountain range. In the studio this can be
achieved by feeding the output of the play head of a tape
recorder or special tape loop deck back to the record heads.
Many electronic devices using digital electronics are available,
and these do much the same job. This effect is normally
reserved as a special effect only, and should not be confused
with reverberation. The sound of reverb is similar to that of a
large empty concert hall. Reflections of the original sound are
so close and diffuse, that no distinct repeats are heard. This
effect is often simulated by devices employing a large metal
plate or torsionally driven coiled springs. The effect is normally
used to fill out the sound of a vocal or instrument which has
been closed-miked, or is otherwise void of natural reverbera¬
tion. Added judiciously it will provide commercial fullness and
body to a recording. Used excessively it can create
exaggerated illusions of space and loss of clarity and
intelligibility.
The echo or reverb effect is proportionately added to the direct
signal passing through the mixer.
The following describes how to connect either an echo or
reverb, or in fact any other effect such as a phaser, flanger,
doubler, etc., to the Model 450 signal path.

processor, post-fader, post-EQ. (A). Aux 1 out to
processor to Buss in; (B) direct out to processor to

input channel, pre-fader, pre-EQ.

NOTE: This method of connecting the effector (Noise
gate, limiter/compressor, chorus unit, etc.) is very effective
when directly processing the original sound.

NOTE: This method of connecting the effector (Digital
delay, reverberation, etc.) is very effective when adding the
processed sound to the original sound.
