3. Controls and indicators

1

Rate

With this control you adjust the transition speed of the
slope created by the slew limiter (see Fig. 1). The
speed can be adjusted to produce transitions from
about 10 down to nearly 0 seconds.

Fig. 1: How the A-171 transforms a signal.

When Rate = 10, the output signal is nearly identical
to the input, i.e. the max. slew speed or min. slew time
is selected. When Rate = 0 one obtains the minimum
slew speed (= maximum slew time, i.e. ~ 10 seconds).

H

Pay attention that the control behaviour of the
A-171 is reverse that of the "normal" slew li-
miter A-170. The control of A-171 is controls the
speed (rate), the controls of the A-170 control
the time.

2

CV 2

Use Attenuator 2 to control the amount of CV input "
to affect the transient speed.

3

LEDs

The LEDs 3 are status indicators of the relative mix
of positive ("+") and negative ("-") signals at the output.
The brighter they are, the higher the voltage.
