Questions and Answers

Q. When I turn up the volume on the KRC-3 a loud hum is present from the loudspeakers; what could it be?

A. Hum can be caused by several different disturbances. Check to make sure all of the cables into and out of the KRC-3 are sound and making proper

contact. Make sure there are no power supplies or hum inducing components on top or directly below the KRC-3.

You could also be experiencing a ground loop in the system. Put a 3 prong to 2 prong AC adapter (cheater plug) on the KRC-3. This should eliminate

the hum. If the hum persists, you may need to repeat this procedure on

additional components in the system. Please contact your dealer or

equipment manufacturer before lifting the ground on any component.

Remember to always keep one major component grounded. If these suggestions do not lead to a solution, please consult your dealer or KRELL.

Q. Can the KRC-3 be used to control more than one system?

A. Yes, the KRC-3 has both single-ended and balanced outputs that can be used simultaneously to control two different systems.

Q. When I select the B1 input on KRC-3, one channel seems to have less gain than the other. Is something wrong with the preamplifier?

A. More than likely there is not a problem with the KRC-3. The balanced input

or output internal cable terminations could be incorrect. Locate the channel of the system that appears to have less gain. Switch that channel's input cables. If the problems now appears in the other channel, it is a defective cable. If the problem remains in the original channel, check the KRC-3 output cables using the same procedure. If it is not cable or source related, call your dealer or KRELL.

Check to make sure there are no Balance LEDs illuminated. If there are, correct the balance by pressing the balance control buttons on the remote control until no LEDs are illuminated.

Q. WhenI use my surround processor, where should I set the volume on the KRC-3?

A. When using the KRC-3's Theater Throughput capability, the system volume

control is performed by the surround sound processor. This eliminates the need to predetermine a proper volume setting for the KRC-3 as the KRC-3's level control is not active in this mode (See Optional Configurations page for more information).

It typically includes multiple analog inputs, such as balanced XLR and unbalanced RCA connections, ensuring compatibility with a wide range of sources, including CD players, turntables, and streaming devices. The unit also boasts a robust output stage that can handle long cable runs while maintaining signal integrity.

Another notable characteristic of the KRC-3 is its precision volume control system. This feature allows for fine adjustments while minimizing the impact on audio quality, ensuring that changes in volume do not compromise the listening experience. Users can enjoy a quiet, noise-free operation, making even the slightest volume changes seamless.

Krell’s dedication to high-quality construction is evident in the KRC-3’s build. The chassis is made from heavy-duty materials, providing a solid foundation that effectively reduces vibrations and external interference. The attention to detail in its design not only enhances its aesthetic appeal but also reinforces its performance capabilities.

The Krell KRC-3 is a synthesis of advanced technologies and meticulous craftsmanship. It encapsulates Krell Industries' mission to provide audiophiles with the tools they need to experience music as it was meant to be heard. With its innovative features and exceptional sound quality, the KRC-3 remains a coveted piece of equipment for music enthusiasts seeking the ultimate in audio fidelity. Whether used in a dedicated listening room or as part of a larger home theater system, the KRC-3 promises to elevate the listening experience to new heights.
