SP33 Pre-Amplifer/Surround Processor
6 pages
Introduction
The SP33 is an audiophile balanced eight channel pre-amplifier/processor featuring full
RS-232 control, comprehensive video switching via 1.4 compliant HDMI and powerful
custom configuration. It is the natural successor to the successful SP32, which was
recognised around the world for its high performance and innovative user interface. As
the first of a new generation of Primare home entertainment products however, the
SP33 represents a considerable evolutionary advance in terms of design, performance,
user flexibility and versatility. It offers a truly modular design platform, which allows for
entire audio, video and control sections to be upgraded easily by superior Primare
versions of the latest technologies.
Modular Design
The SP33's comprehensively shielded heavy-duty steel chassis houses a newly
developed modular design that allows for DSP, video and connections to be upgraded
easily with proprietary Primare boards, incorporating thoroughly evaluated and
optimised versions of the latest technologies and connectors.
In every instance we have taken special care to keep signal paths short and layouts
uncomplicated. Together with high performance FFC-wiring, these techniques give the
unit an extremely high performance and the highest possible signal-to-noise ratio. The
finest audio grade semiconductors and capacitors have been used whenever possible. All
parts that are known to interfere with each other are isolated by shielding, dedicated
signal paths and power supplies.
