INFORMATION

 

Thank you for

purchasing the

KRELLKSP-7B Preamplifier.

The KSP-7B is

the latest evolution of KRELL'sentry 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 KRELLpreamplifiers have

become recognized: internally switchable loading for moving coil cartridges

and input capacity rarely found on high-end preamplifiers. All circuitry in the KSP-7Bis 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.

KSP7B specifications

Krell Industries is renowned for its high-performance audio equipment, and the KSP7B is a prime example of their commitment to exceptional sound quality. The KSP7B is a stereo power amplifier that embodies Krell's long-standing tradition of creating products that deliver superior audio, making it a popular choice among audiophiles.

One of the main features of the KSP7B is its robust power output. With a power rating of 200 watts per channel into 8 ohms and 400 watts per channel into 4 ohms, the KSP7B is capable of driving a wide range of speakers with ease. This power enables the amplifier to produce dynamic sound without distortion, even at higher volumes. The design incorporates a heavy-duty power supply that ensures stability and reliability, allowing for optimal performance across different audio frequencies.

The KSP7B utilizes Krell's proprietary technologies. One such technology is the unique Class A biasing, which allows the amplifier to operate in Class A mode at lower powers, enhancing sound quality by reducing crossover distortion. This feature allows for incredibly detailed and nuanced sound reproduction, ensuring that every note and nuance is preserved. Additionally, the amplifier features an advanced cooling system that maintains optimal operating temperature, which is essential for consistent performance and longevity.

Another standout characteristic of the KSP7B is its dual-mono design. This design approach allows for more precise channel separation, thereby reducing crosstalk and improving imaging. As a result, listeners can experience a more immersive soundstage with distinct, clear separation between instruments and vocals. This characteristic makes the KSP7B an excellent choice for critical listening environments.

The build quality of the KSP7B is exceptional. It features a solid aluminum chassis that provides both aesthetic appeal and durability. The front panel is elegantly designed with minimal controls, emphasizing its high-end nature. The rear panel includes multiple input options, including RCA and balanced connections, ensuring compatibility with a wide range of audio sources.

In summary, the Krell Industries KSP7B stereo power amplifier combines high power output, innovative technologies, and impressive build quality. It caters to the needs of serious audiophiles who seek unmatched performance. Whether you're listening to a favorite album or enjoying a cinematic experience, the KSP7B is designed to deliver sound that is both powerful and precise, making it a definitive choice in the realm of high-fidelity audio.
