Krell Industries KPA, KBL specification

d.Power Supply Installation

1.Place the powersupply(s) in location.

2.Connect the DCcable(s) from the supply(s)to the preamp(s)

3.Plug the DCjumper between the KBL(s) and KPA(s).

4.Donot plug the ACconnector(s) into the mains at this time.

7.Connection of Inputs and Outputs

All source componentsand amplifiers should be off at this point.

Whenconnecting balanced components to the KBLvia RCAconnectors be sure to maintain proper polarity of the non-inverted and inverted inputs. The non-inverted inputs are the Left connectors on the top row; the inverted inputs are the Right connectors on the bottom row. Also, if you are using two KBLin dual-mono, remember that the Left XLRsare operational and the Right XLRconnecters are disabled.

a.Connection of Input Sources

1.Connection of the KPAInputs and Outputs

Either input can accommodate a moving magnet or moving coil cartridge.

Single KPA:connect the cartridge outputs to the KPAinputs 1 &2 in the conventional manner.

Dual KPA.balanced in~)ut wiring from the cartridge(s); connect the "high" (left = white, right = red) output from the cartridge to the left

input connectors on the KPAs.Connect the "low" (left = blue, right green) to the right input connectors on the KPAs.Typically the top unit is used for the left channel and the bottom unit is used for the right channel.

The output of the KPAis high-level input and can be sent to any input on the KBL(s). Connect the output of the KPA(s) to the

inputs at this time.

2. Connection of KBLInl~ts

The inputs of the KBLhave not been labeled with specific component namesso you can set up the Select switch pattern to your preference. B-1 and B-2 refer to Balanced inputs 1 &2; S-l, S-2, S-3, S-4 refer to Single-ended inputs 1 through 4. Once you have decided which componentwill be assigned to which input, proceed with connecting the source componentsto the desired inputs.

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.
