Since November 2021, Todd Eichenbaum has been Senior Principal Electronics Engineer for JL Audio, Inc., where he researches and designs analog and mixed-signal electronics for amplifier and speaker products. He also participates in the investigation of new amplifier technologies and the subjective “voicing” of electronics and speakers.

Prior to this, starting in 2013, Todd was Director of Engineering for the Luxury Audio business unit at Harman International Industries, Inc., where he oversaw the Electronics Engineering Center of Excellence
in Shelton, CT until its relocation in 2021. There he assembled and led a team of nine engineers in the design of fifteen new Mark Levinson #500-series and #5000-series home audio products. Todd also collaborated with Harman’s top automotive engineers in the US and Japan on the design and tuning of Mark Levinson sound systems in Lexus automobiles.

Before joining Harman, Todd was Director of Engineering at Krell Industries, Inc., where he worked for over 21 years from 1988 to 1995 and again from 1998 to 2013. During that time, he designed or oversaw the design of more than 60 preamp, power amp and loudspeaker products, dating as far back as the KSP-7B preamp and KSA-250 power amp, and continuing through the Full Power Balanced amps, the Evolution product line, and the iBias concept. He was also the primary collaborator on the Krell automotive sound system that debuted in the 2014 Acura RL-X.

From 1995 to 1998 Todd was Senior Engineer at Precision Power, Inc. During that time, he designed the PPI 2500F1, a flagship, limited-production, 500 watt-per-channel, discrete automotive power amp, as well as a novel line of hybrid vacuum tube/solid state automotive stereo power amps. In addition, Todd worked on PPI’s “tweak and tune” team, helping tune vehicles for competition and demonstration.

Before joining Krell the first time, Todd received his BSEE degree from Northwestern University in 1986, and his MSEE degree from Stanford University in 1988. He had a brief internship at Koss Stereophones in 1987. He was active in Eta Kappa Nu and Tau Beta Pi engineering honor societies, and he also won Northwestern’s William T. Faricy Award for Creative Art in 1983.

Todd lives in Connecticut with his wife and some combination of his sons, where he enjoys spending time with family and friends, cooking, and listening to jazz.
