Control Voltage Supply
All user interface digital and control circuits, source their power from an
isolated DC supply. The supply features a custom wound, multi tap
toroidal transformer directly soldered to the PCB. By incorporating a
separate control supply, it minimises the possibility of noise entering the
audio circuitry.
Preamplifier Voltage Supply
The preamplifier section is also powered from it’s own separate low
voltage supply, thereby further reducing the possibility of noise entering
the audio circuitry.
Separate Left and Right Channel Power Supplies (Dual-Mono)
The concept behind dual-mono topology is to incorporate two amplifiers
within a single enclosure. By incorporating 2 x high quality power
supplies into the design, the R200i maintains maximum channel separation.
Huge Smoothing Section
Four filter capacitors (40,000uF per channel, 80,000uF total) per channel
are coupled in parallel for greatly reduced power supply resistance and,
consequently, significantly improved dynamic capabilities.
The sonic benefits of a power supply as high a quality as the R200i has are
significant, resulting in effortless reproduction of dynamic contrast as well
as stable and detailed stereo imaging.
The
Preamplifier
Section
The preamplifier features five analogue input pairs. Four pairs of single
ended RCA inputs and a single pair of balanced XLR inputs.
A high quality, class A phono stage can be installed within the R200i.
Alternately, provision is allowed for to fit a Perreaux designed and built
digital USB interface module, featuring a very highly specified digital to
analog converter (DAC).
Two single ended output pairs are also provided: A pair of single ended
“direct” and “preamplifier” outputs.
Perreaux engineers have carefully eliminated any signal borne noise at the
input, before the possibility of propagation occurs. In addition to this, only
highest quality components such as “Burr Brown” and “Crystal’ are used
throughout the preamplifier stage. The result is a low noise, highly
dynamic and detailed resolution of the connected source.
