PA Electronic Reverb Control
(320-1107)                 Operation                  Faxback Doc. # 32637

Your electronic reverb control has three basic controls - DELAY, REPEAT,
and DEPTH.  You can use these controls in different combinations to
create many sound variations.

DELAY

The DELAY control changes the amount of time between the original sound
and the delayed sound.  You can vary this time from about 5 milliseconds
(5/1000ths of a second) at a control setting of 0, to 95 milliseconds
at a control setting of 10.

REPEAT

The REPEAT control varies the number of echoes created by the original
signal.  The number of echoes that you can create depends on the strength
of the original signal.

DEPTH

The DEPTH control varies the strength of the delayed sound in relation
to the original sound.

For example, with DEPTH set to maximum (10), the strength of the delayed
sound is almost equal to the original sound.  With DEPTH set to minimum
(0), you hear only the original sound.

FAVORITE EFFECTS

REVERBERATION

You can reverberate (delay) sounds to simulate the live sound of
a large auditorium by using a short-to-moderate delay time (DELAY control
setting of 3-6).

ECHO

The echo effect is a sound that is repeated at specific intervals with
each repetition diminishing in volume.  You can echo sounds by using
a relatively long delay time (DELAY control setting near 10).  You can
also vary the REPEAT and DEPTH settings to achieve the desired effect.

FLANGING

You can flange (distort) sounds by using a relatively short delay time
(DELAY control setting 0 to 4) while varying the DEPTH control from
minimum to maximum.  Set REPEAT to 0.

NOTE:  The flange effect was originally achieved by applying amounts of
       hand pressure to the flange of a tape reel during recording or
       playback.

DOUBLING

You can double sounds to create an effect similar to overdubbing or
recording one sound on top of another, by using a short-to-moderate
delay time (DELAY control setting of 3 to 7).  Set REPEAT at 0, and
the DEPTH control at high (8 to 10) and keep it constant.

SLAP-BACK

The slap-back effect (similar to an echo) is a sound that is repeated
once and the volume is not diminished.  You can slap-back (repeat) sound
to create an effect similar to the sharp, hollow echo of a chamber.

Slap-back uses a DELAY control setting of 60-80 milliseconds (a setting
of about 8).  You can vary the REPEAT and DEPTH controls to enhance this
effect.
