Co Wheninstalling th'e KSP-7B,always connect the DCcable between the

preamplifier chassis and the power supply before plugging the power supply into the ACmains.

e. The KSP-7BSelect switch should be in the Mute position and the volume control fully counterclockwise while making connections.

Our custom RCAconnectors are made to very exacting standards. Connectors of lesser quality may damage them or cause poor

connections. Please check with your dealer or the factory if you have any questions.

2. Unit Location Guidelines and Installation

The KSP-7Bis designed to be set-up with the power supply installed at some distance from the preamplifier chassis. This is to eliminate the possibility of hum being induced into the phono section. The motors in CDplayers or tape decks can also induce huminto the phono section and, in most cases, should be placed at least a foot away from the KSP-7B.

Before proceeding with the final installation, please read and complete the set-up of the phono section loading. These operations involve removal of the top cover and are much easier to accomplish before the unit is fully in place. Instructions and settings are listed in Section B (Pages 2 &3).

a. Power Supply Location Guidelines

The KSP-7Bpower supply measures 7 1/4" wide, 8 1/4" deep and 2 1/2" high. Six foot ACand DCcables are provided with the supply. Plan the position of the supply and preamplifier within these lengths. Allow a small amountof cable to be excess so that neither cable is pulled tight.

Contact the factory if the DCcable is too short. Anyattempt to extend it jeopardizes the power supply and the preamplifier and will void the unit's warranty.

Although well-shielded, the power supply should not be placed close to

hum-sensitive components such as turntables, phono preamplifiers or tape decks.

Allow ample air space around the supply for heat dissipation. Five inches on top and two inches on each side is adequate. This supply and any other should not be placed one on top of the other. They should be placed side-to-side.

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.
