MovingCoil Cartridges:' The KSP-7Bis shipped with the phono section gain set for moving coil cartridges and a load of 800 ohms. The load can be changed with a set of internal switches. To access these the top cover must be removedwith the supplied allen driver. At the left-rear of the unit there is a two-position toggle switch. In the factory-supplied position the switch lever is towards the rear panel of the unit. If you are using a movingcoil cartridge do not change the switch position. To adjust the input impedance load for different moving coils use the table below to find the optimum setting for your cartridge. Follow your dealer's or the manufacturer's

~recommendations first. You can also set the load using your sonic preferences as a guide. In general, lowering the impedance will make the high frequencies less prominent and the overall sound warmer. Higher

loads makethe overall sound more vivid and detailed. This is, of course, highly ~ubjective and very dependent on the cartridge in use.

The various load possibilities are detailed below:

Moving Magnet Cartridges: To set the Phono section for Moving Magnet operation, with the impedance adjusted to 47,000 ohms, set the phono gain switch towards the front of the preamplifier. This lowers the gain of the phono section to compensate for the higher output of moving magnet cartridges. Set all impedanceswitches for both channels to off.

C.INSTALLATION

1. Cautions!

Note: These are important points of which you always should be aware. They are presented before the actual installation procedures, should you not

read through the manual entirely.

a.Do not connect the power cord into the ACmains before completing the "Installation" section!

b.The power amplifier(s) should always be turned off while making connections.

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.
