INTRODUCTION & GENERAL INFORMATION
Thank you for purchasing the KRELL KSP-7B Preamplifier. The KSP-7B is
the latest evolution of KRELL’s entry level preamplifier technology. Many
of its design concepts are similar to our more expensive preamplifiers and
are wholly unique to KRELL. Two important design features are dual-
mono operation (all active stages are powered by independent tracking
regulators) and the complete absence of any capacitors in the signal path.
The KSP-7B retains other features for which KRELL preamplifiers have
become recognized: internally switchable loading for moving coil cartridges
and input capacity rarely found on high-end preamplifiers. All circuitry in
the KSP-7B is of completely new design -- many aspects of which are derived
from the top-of-the-line KRS-Balanced Reference Preamplifier. The most
significant of these is the fully balanced output stage. Balanced circuitry
has long been standard for professional audio equipment and is rapidly
becoming the standard for high-end audio equipment. The sonic benefits of
balanced operation are clearly audible. A simple listening comparison
between the RCA (single-ended) and the XLR (balanced) outputs will reveal
improvements in all areas of sonic quality. The connection of the KSP-7B in
single-ended and balanced systems is covered on page five.
Please read this manual thoroughly before using the KSP-7B. Installation
and operation are simple to understand and perform.
The KSP-7B will provide many years of trouble-free performance. Please be
sure to return the enclosed warranty registration card.
