i. For use with an~plifiers with single-ended (unbalanced) inputs: connect the RCAMain Outputs to the amplifier inputs. This constitutes the conventional hook-up for a single-ended unbalanced system.

ii.For use with amplifiers with balanced inputs: connect the XLRMain Outputs to the amplifier inputs. The pin assignments are as follows: 1 = ground, 2 = non-inverted output, 3 = inverted output.

Make the connections between the Main Outputs and amplifier(s) and/or crossovers at this time.

4. Turn-on of the Preamplifier

a. Initial Tam-on

All source components should be off at this point. The Select switch

should be set to the Mute position and the volumecontrol should be fully counterclockwise. The amplifier(s) should be off.

Connect the power supply to the ACmains at this point. The LEDson the power supply and KSP:7Bshould now be illuminated.

b. Future Use

The KSP-7Bis designed to be "on" at all times. In other words, it is not intended to be switched on and off on a routine basis. The only times it is recommended to turn the unit off is when your system will be left unattended for a long period of time, such as during a vacation or a

business trip. In these cases all other equipment should be turned off, and the KSP-7B power supply should be disconnected from the AC

mains. Whenyou return, reconnect the power supply to the ACmains before turning on other equipment.

This procedure should also be followed if you reorganize your system and need to change wiring of the supply to the preamplifier.

D.OPERATION

Use the Select switch to choose between the various source (playback)

components for listening. Be sure to lower the volume control when switching amongcomponents, as large differences in level between sources can cause damage to other components.

There is a Mute position that should be used when source components are being turned on and off and at the completion of each listening session.

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.
