1. getting started
The topology of the volume
control used in the RI-100 is
very different compared to the
“standard”. The RI-100 uses a
series of fixed resistor networks
to control the volume. Relays
are used to switch between the
resistor networks. Across all
volume steps, a fixed resistor
is in series with the signal
path. This gives the best per-
formance possible. When you
change volume, a different
number of shunt resistors are
used.
To prevent pop in the output,
we have chosen to first add
the new shunt resistors, and
then wait a short time, before
removing the unused shunt
resistors at the new volume
step. This will give a minor fall
in volume before settling at
the new volume step. It takes
only very little time to get
used to this type of operation
of the volume, and it will give
you superior sound quality
over the traditional digital and
analogue potentiometers.
