The Iron Age LH95 is a highly flexible, discrete class A active equalizer in the 500 series format. It features a discrete audio path, three vintage class A gain blocks, transformer balanced inputs and outputs, and an inductor mid band.
The equalizer is set up for broad, musical adjustments on the high and low end of the audio band with an active Baxandall stage. The high and low bands allow for up to 15 dB of shelving boost or cut in 3 dB increments, at 40 Hz for bass and 15 kHz for treble.
The mid band stage is a variable frequency presence filter using a custom-wound multitap inductor from Cinemag. It provides up to 8 dB of boost or cut in 2 dB increments. Boost and cut frequencies are approximately mirror-inverted.
Additionally, the EQ features switchable high pass and low pass filters with -3 dB points at 75 Hz and 13.5 kHz.
