Four inches clearance should be allowed above the top of either the KBLor KPA. Only a small amount of clearance is needed on the sides. Four to six inches clearance should be allowed at the rear of either unit to provide for cables.

3.The units can be stacked. KPA(s) should be placed on the bottom with KBL(s)on top.

KPA(s) are sensitive to induced hum from motors or power

supplies. In general, they should be located at least one foot from other components (with the exception of the KBL). In particular, power supplies, tape recorders, and turntables should be more than a foot away from the KPA(s).

b.Preamplifier Installation

Place the preamplifier(s) in position. Checkthat all cable lengths are adequate at this point.

c.Power Supply Location Guidelines

1.The KBLsupply measures 9.75" wide, 12" deep, 2.25" high The KPAsupply measures 7.25" wide, 7.75" deep, 2.5" high (Only KPAnot powered from a KBLhave a separated supply)

2. Six foot ACand DCcables are provided with the supply(s).

Plan the respective position of the supply(s) and preamplifier(s)

within these distances. Allow at least excess, so neither cable is pulled tight.

a small amount of cable to be Contact the factory if the DC

cable is too short. Any attempt to extend it jeopardizes the power supply and the preamp, and will void the unit's warranty.

3.Although well shielded, the power supply(s) should not be placed

close to hum-sensitive components such as turntables, phono preamps or tape recorders.

4.Allow ample air space around the supply(s) for heat dissipation. Five inches on top and two inches on each side is adequate. Two supplies should not be placed directly on top of each other. They should be placed side-to-side.

5.The KBLor KPAsupplies do not require that an ACVcircuit be dedicated for their use. They should be connected to a 15 or 20 amp circuit that is dedicated for the source components and the

preamplifiers. Do not connect them to the mains with light-gauge (18 or higher) extension cords or multiple outlet adapters. extension cords, outlet strips and good quality surge protectors that are rated for 15 amps and grounded are acceptable.

Krell Industries KBL, KPA owner manual

KBL, KPA specifications

Krell Industries, a name synonymous with high-fidelity audio, has made significant strides in the high-end audio equipment market with its KPA and KBL models. These amplifiers epitomize Krell's commitment to exceptional sound quality, advanced technologies, and innovative design, catering to audiophiles who seek unparalleled listening experiences.

The Krell KPA, a cutting-edge power amplifier, showcases Krell’s renowned high-performance design. One of its standout features is the use of an ultra-linear, class-A amplification topology. This design principle not only enhances audio fidelity but also ensures lower distortion levels, allowing music to be reproduced with incredible detail and clarity. The KPA is also engineered to deliver substantial power output, with sufficient reserves to drive even the most demanding speaker loads, making it an ideal choice for dynamic music genres.

Another noteworthy aspect of the KPA is its sophisticated thermal management system. The use of oversized heatsinks and intelligent fan control keeps the amplifier cool during extended listening sessions, thereby preserving performance and longevity. The KPA also includes advanced connectivity options, including RCA and XLR inputs, which cater to a variety of system configurations, ensuring versatility in integration with other high-end audio components.

Conversely, the Krell KBL, a preamplifier model, is designed to complement the power capabilities of the KPA. The KBL's main features include a fully balanced design and multiple gain stages that contribute to its exceptional signal-to-noise ratio. This ensures that the audio signal remains pristine, free from interference and distortion, resulting in a true-to-life reproduction of recordings. The preamplifier also offers an impressive array of inputs, including analog and digital options, allowing users flexibility in their source selection.

Both the KPA and KBL incorporate Krell's proprietary technologies, such as the Cast™ technology, which facilitates a three-dimensional soundstage and unrivaled musical character. This technology seamlessly enhances the relationship between components, creating a cohesive sound that many audiophiles strive for. Furthermore, the build quality of both models is exceptional, with premium materials and craftsmanship that reflect Krell's dedication to performance and aesthetics.

In summary, Krell Industries' KPA and KBL models combine innovative technologies, remarkable power, and unmatched audio quality, making them ideal choices for serious music lovers. Their features, performance, and elegant design showcase Krell's unwavering commitment to the pursuit of audio excellence, setting new standards in the high-end audio luxury market.
