About the KBL
The Krell KBL is a solid-state, pure Class A, DC-coupled stereo line preamplifier with an external power supply. Its fully discrete, complementary circuitry provides a 65V peak-to-peak output swing, approximately 9dB of gain, a 0.5-ohm output impedance, and a stated frequency range of 0.1Hz–250kHz. The rear panel provides one balanced input, four single-ended inputs, one balanced output, and one single-ended output. The KBL has a 10k-ohm input impedance and a 100dB A-weighted signal-to-noise ratio. The preamplifier measures 2.25 inches high by 19 inches wide by 12 inches deep; its power supply measures 2.5 inches high by 9 inches wide by 12 inches deep. Two KBL units can be used as a dual-mono pair.
