e most signifi cant factor in the perceived responsiveness of the volume control
is the speed at which the knob is being turned. We all naturally tend to move
volume knobs more quickly when we need to make a bigger change, and we
tend to slow down as we approach our desired volume.  us, if the CP-700 sees
the knob moving relatively quickly, it uses coarse steps to eff ectively accelerate
the action of the circuitry. As the knob begins to turn more slowly, the CP-700
will actually increase the resolution of the steps, which slows down the action
of the volume control and yields greater precision in choosing an appropriate
setting.
Of course, it is possible to bump into the knob by accident, which might
result in its spinning very quickly indeed. Rather than increasing the volume
uncontrollably under these conditions, the CP-700 actually slows everything
down again as a safety measure against accidentally blowing your speakers. In
fact, if you like you may establish a speed limit beyond which the knob will
simply be ignored.
e factory default settings for these behaviors are generally found to be intuitive
and a pleasure to use. However, if you prefer to alter these behaviors, you may do
so in the rotary menu, shown below.
All of the rotary setup settings are interactive. You can set the value, and then
adjust the volume to see whether the eff ect is what you desired.
low range: determines the degree to which the responsiveness of
the volume control is boosted at low volume control settings, in
order to get through them more quickly. A setting of 0 disengages
the eff ect, while a setting of 100 maximizes it.
low speed: determines the responsiveness of the control when the
knob is being turned slowly. A setting of 0 will cause the volume
to change as slowly as possible at low knob speeds; a setting of
100 will cause the volume to change as quickly as allowed at low
knob speeds. ( e menu is the same as the one above except for the
indication that it is for the “low speed” adjustment.)
