SPHINX Project Eighteen Service Manual
The Sphinx Project Eighteen design
The Sphinx Project Eighteen was designed for the
ever-increasing group of quality-conscious
audiophiles.
We are very proud of the tradition connected with
the SPHINX name, especially concerning audio
quality perfection.
This service manual will help you to optimally
service and repair the Sphinx Project Eighteen True
Dual Mono Power Amplifier.
The power amp handles the largest signal peaks
and transients with ease, and has no problem with
any size and type of loudspeaker load: even the
most demanding.
These characteristics are the result of several new
technologies and components. For instance the
unique power supply which assures a stable and
noise free operation. The special toroidal
transformer (one for each channel!) of 650 VA has
the size of a 1000 VA model: safely over-specified.
Thanks to the generous energy reserve of 66,000
µF (formed by 30 capacitors in parallel), unlimited
power is available for the largest signal peaks.
Furthermore there are three completely separate
power supplies for the input section, driver section
and the logic and indicator section.
Much attention has also been paid to the physical
layout, the positioning of components and the
internal grounding. This results in a equivalent input
noise value of <1 µV (<-120 dBV): remarkable for a
pre-amp, but really astounding for a big power amp
with two transformers.
All of this means that the Project Eighteen can work
with all kind of loads from every loudspeaker: even
the most difficult ones like electrostatic and
magnetostatic...
To obtain the maximum quality from this power amp
it is necessary to use it with top quality audio
components preferably with other Sphinx
components.
Please also refer to the User Manual of the
Project Eighteen for information about
functions not described in this manual.
It is important to familiarise yourself with the
special functions, operation and possibilities
of the Sphinx Project Eighteen.
