Eisen Audio LILPEQr

Eisen Audio LILPEQR LE60 Program Equalizer is an equalizer module for the 500 series.

History
The Eisen Audio LILPEQR was limited to 60 units, and had vintage Marinair and St. Ives input transformers. The module was re-issued, with custom-made transformers, as Purple Audio LilPEQr.

Official description
John Klett had a large stockpile of vintage Marinair and St. Ives input transformers, left over from custom Neve console projects, so he suggested Eisen Audio design a product in which to utilize them. 31267 is a very colorful sounding transformer, with a rich low end, so Jens at Eisen Audio took this opportunity to make solid-state 500 Series EQ module which would emulate some of his favorite vacuum tube program equalizers. This input transformer was paired with a Crimson Audio output transformer, which is “bigger sounding” than most, interfacing with a purpose-designed discrete transistor amplifier and some carefully selected film capacitors. Jens deliberately chose/designed each of these elements to impart an overt and complementary tonal response, trying to achieve a spectral distribution of low-level harmonic distortion which was similar to that of the classic devices which inspired this one. A limited edition of 60 units was sold direct through Eisen Audio during the ’07-’08 holiday (one-time only, discontinued).
