KBL & KPA OWNERS’ MANUAL.
45 Connair Road Orange, CT 06477-0533, USA KBL & KPA OWNERS’ MANUAL INTRODUCTION Thank you for your purchase of a new KRELL preamplifier. This Owners’ Manual covers both the KBL and KPA preamplifiers, as they have been designed to be companion pieces and can be utilized in varying combinations.
D. Installation: 1. Caution 2. Connector Details 3. Connector Termination Types 4. Cable Requirements for Inputs and Outputs 5. Setting of Internal Switches 6. Unit Location Guidelines and Installation 7. Connection of Inputs and Outputs 8. Turn-on of the Preamplifiers E.
These units are the current state-of-the-art. No compromise was allowed in their design. Details concerning their technical performance are covered in more detail below, A second important consideration was to introduce the programmable concept employed in our current KSA/KMA amplifier line into our preamplifier line.
Both preamplifiers have innovative operational features. The KBL has two balanced inputs and one set of balanced outputs in addition to four single- ended inputs and one set of single-ended outputs. This allows one KBL to accommodate balanced line sources and amplifiers, which Krell believes to be the standard for high-end audio gear.

2. Connector Details This section, with sections 3 & 4 below, presents all details necessary to make or modify cables for use with all combinations of the KBL and KPA. After reading these sections, check all the cables you intend to use to make sure they are appropriate for your installation.
All Krell Industries and Krell Digital products use this pin-out for inputs and outputs. c. Balanced RCA Terminatiom uses two-conductor coaxial cable: See Drawing 1 at the rear of the Manual for details. 1 pr. of RCA connectors are used on each end of the cable with this termination; 4 prs.
Read the portions of sections a and b below that pertain to your system for the specific cable terminations required. If you are adding to your system you may need to change some cable terminations to take full advantage of dual-mono, balanced operation.
Please read this section to determine if you have the need or desire to change the internal switches. a. KBL Stereo~D~al-M0n0 ~witches These switches are used to change the KBL between stereo and mono operation. Their most common use is to change an existing KBL from stereo to dual-mono when installing a second KBL for dual-mono.
Four inches clearance should be allowed above the top of either the KBL or 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.
d. Power Supply Installation 1. Place the power supply(s) in location. 2. Connect the DC cable(s) from the supply(s)to the preamp(s) 3. Plug the DC jumper between the KBL(s) and KPA(s). 4. Do not plug the AC connector(s) into the mains at this time. 7.
b. Connection of KBL Record 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. Make the connections between the Record outputs and tape recorders at this time.
E. OPERATION 1. KPA Functions Use the Select switch to choose between two different cartridges or tonearms. If the two inputs are not the same type cartridge be sure to change the gain with the Gain switch to avoid any overload conditions. See section c below.
This switch can be operated while listening to the KPA at normal levels without risk of damage to the preamplifier, amplifier(s) or speakers. Its setting is a matter of personal taste. f. RIAA Adjustment. 20 KHZ Use this switch to make subtle adjustments to the high end of the RIAA equalization curve.
Input B-2 on the Monitor switch uses only the non-inverted signal. Therefore, if you are feeding a balanced signal into B-2, there will be a 6 dB difference in level between B-2 on the Select switch and on the Monitor switch. The level on the Select switch will be the higher one.
When the control is turned clockwise the left channel is attenuated; when turned counterclockwise the right channel is attenuated. The LED indicators may illuminate at high listening levels. This indicates that a level difference exists between the left and right channels at that moment.
