Primare SP32 Manual

SP32 PRE-AMPLIFIER/SURROUND PROCESSOR
INTRODUCTION
The SP32 is an audiophile balanced eight channel pre-amplifier/processor featuring full RS-232 control,
comprehensive video switching via 1.3 compliant HDMI and powerful custom configuration. It is the natural
successor to the successful SP31, 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
SP32 represents a considerable evolutionary advance in terms of design, performance, user flexibility and
versatility. It is one of the first Primare products to offer 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 SP32'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. This makes the SP32 an
ideal high-end audio and video processing platform for many years to come (for upgrade features see
inputs/outputs section).
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.
OPERATIONAL VERSATILITY
Almost every parameter in the configuration of the SP32 can be user defined. Any input can be assigned a name
and associated with any audio and video source. Surround format, trigger activation and input sensitivity can be
specified for the input. Individual levels, speaker types, crossover frequencies and delay configurations including
bass management can be selected for each of the major surround formats. A 140mS global delay system, with
dedicated DSP, is incorporated in order to achieve the best possible picture to sound synchronisation. For the
highest possible installation flexibility, all the SP32's functions can be controlled in three ways: from the front
panel, IR or RS232.
