1. GETTING STARTED
The topology of the volume control
The topology of the volume control used in the RI-101 Mk.II is very
different compared to the "standard". The RI-101 Mk.II 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 performance possible. When you change volume, a different
number of shunt resistors are used.
10 | RI-101 Mk.II Owner's manual
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 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.
Turning the RI-101 Mk.II on and off
Always turn on the products beginning from the source:
Source
pre-amplifier
power amplifier
Always turn off your products in reverse order:
