Krell Industries KBL, KPA specs

b. Connection of KBLRecord Outputs

There are two Record outputs which receive the signal from the input chosen on the Select switch for sending to two tape recorders. The two outputs are wired in parallel and have no relation to any of the inputs.

Makethe connections between the Record outputs and tape recorders at this time.

c. Connection of the KBLMain Outputs

There are two sets of Main outputs: one set single-ended on RCAs', one set balanced on XLRs. They are wired in parallel and can be connected

and operated simultaneously. They are provided to drive two independent systems from one preamplifier.

8.Turn-on of the Preamulifiers a. Initial Turn-On

All source components and amplifiers should be off at this point. The KPAand KBLSelect switches should be set to "Mute" position, and the KBLvolumecontrol(s) should be fully counterclockwise.

Connect the KBLand KPA(if a separate supply is being used for the KPA)power supply(s) to the ACmains at this point. The LED's on

power supply(s) and on the preamplifier front panel(s) should illuminate. Noneof the other LEDs'should be illuminated at this point.

b. Future Use

The KBLand KPAare designed to be on at all times. In other words,

they are not intended to be routinely switched on and off. The only times it is recommendedto turn the units off is whenyour 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 KBL/KPApower supply(s) should be disconnected from the mains. Whenyou return, re-connect the supply(s) to the ACmains before turning on other equipment.

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

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.
