This supply does not' require that an ACcircuit be dedicated for its use only. It should be connected to a 15 or 20 ampcircuit that is dedicated for the source components and preamplifier. Do not connect this supply to the mains with light-gauge (18 or higher) extension cords or multiple outlet adapters. ACextension cords, outlet strips and good quality surge protectors that are rated for 15 amps and are grounded are acceptable.

b. Preamplifier Location Guidelines

The KSP-7Bchassis measures 18 3/8" wide, 13 1/2" deep and 2" high. Four inches clearance should be allowed above the top of the KSP-7B. Only a small amount of clearance is needed on the sides. Four to six inches clearance should be allowed at the rear of the unit to provide for cables.

c.Power Supply & Preamplifier Installation

i.Place the power supply in location.

ii.Place the preamplifier in location.

iiiConnect the DCcable from the supply to the preamplifier.

iv.Do not plug the ACconnector into the mains at this time, but make certain the cable length is adequate.

3.Connection of Inputs and Outputs

All source componentsshould be off at this point.

a. Connection of Inuut Sources

Follow the markings on the rear panel for proper input assignments. Make the connections between the source components and preamplifier inputs at this time.

b. Connection of Record Outuuts

There is one set of Record Outputs which receive the signal from the input chosen on the Select switch for sending to a tape deck. Makethe connections between the Record Outputs and tape deck at this time.

c. Connection of Main 0~tputs

There are two sets of Main Outputs: one set single-ended using RCA connectors; one set balanced using XLRconnectors. They are wired in parallel and can be connected and operated simultaneously. There is no degradation to either output if both are connected, whether one or both are in operation at the same time. You may even choose to drive two independent systems from your KSP-7B.

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.
