Please read this section to determine if you have the need or desire to change the internal switches.

a. KBLStereo~D~al-M0n0 ~witches

These switches are used to change the KBLbetween stereo and mono operation. Their most commonuse is to change an existing KBLfrom stereo to dual-mono when installing a second KBLfor dual-mono. There

is one double-toggle, two-position dip switch between the input

connectors for B-1 (SW6) and for B-2 (SW7); there is a third near balanced output connectors (SW8).

All three switches mu@tbe set the same. They are not to be set in any other combination.

-Positions C2 &C4 depressed are for stereo operation. -Positions C1 &C3 depressed are for monooperation.*

*In dual-mono operation only the lef~ XLReQnneqt0r~ are operational;

the right connectors are disabled. All RCAconnectors remain operational, but with different functions. See section D3, Connector Terminations, below for details.

6. Unit Location Guideline~ and Installation

Before installation of your KBL/KPA(s)and power supply(s) we recommend that you follow these guidelines in choosing proper locations for the units.

This will help insure a trouble-free installation and maximum performance of the preamps.

All associated equipmentshould be turned off at this point.

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.
