our processors giving a true recreation of the original music performance, without
the colorations normally associated with integrated circuits.
BALANCED OUTPUT
The SBP-64X provides balanced outputs for those with the complimentary
components which allow them to obtain still lower noise and distortion, while pro-
viding~ore specific imaging.
CLASS iX" ANALOG DESIGN
The analog section of the SBP-64X is based on classic Krell High bias, Pure
Class "A" design which has already set new standards for excellence in musical integrity.
POWER SUPPLY
The power supply for the SBP-64X, housed in a separate outboard enclosure,
provides the five separate voltages required by the Digital circuitry, DACs, and Analog
output stages. In actuality there are three completely independent power supplies and
ten cascaded discrete regulators to supply the five voltages,
NO OPTO-COUPLING
The sophistication of our designs provides a degree of stability and isolation
that surpasses any need for opto-coupling, and their inherent bandwidth and linearity
limitations.
KRELL DIGITAL TECHNICAL ASSISTANCE GLOSSARY
The following glossary represents simplified explanations for key words or
phrases encountered in the course of this manual.
32kHz
The sampling frequency of Satellite broadcast.
44.1kHz
The sampling frequency of Compact Discs.
48kHz
The sampling fl’equency of Digital Audio Tape.
ACCUMULATOR
A work and storage area where data is held and computed in a Digital Signal
Processor.
The accumulator must be large enough not only for the target data, but also for
the end product of the computation. As the precision of computations increases, the
larger the resulting end data will be. Therefore, the size of the accumulator places a
limit on the potential precision of a processor.
BALANCED OUTPUT
A method of isolating the outputs from ground which offers increased gain,
superior imaging, and isolation from external interference. Balanced output
operation on the SBP-64X requires a preamp with corresponding balanced inputs.
BIAS
A current or voltage applied to a transistor to control the linearity of its
operation. Generally speaking, so long as the transistor is kept within its tolerance
range, higher bias will improve transistor operation.
BIT
The fundamental building block of digital information. The term, expressing
the smallest part of a digital word is derived from the words Binary DigiT.
BOOT
Booting is a term loosely referring to initializing the startup sequence in a
computer.
BYTE
A group of 8 bits. The primary component in a digital word.
