Pleiades High Pass Microphone Impedance Matching Transformer

Deep low cut extremely high pass filter

Free passive amplification

Few turns on a high permeability index toroidal tape wound core such as Magnetec's nanoperm M-073

For dynamic, ribbon, condenser microphones at mouth diaphragm distance<1in

Compensates with makeup gain for the proximity effect, voice effort eq, Fletcher Munson curves

Matches the 200 ohms output impedance of mics to the 2000 ohms input impedance of modern preamplifiers

Maximum transfer of energy (no mismatch reflections)

For crystal clear studio quality sound production

Uses Nanoperm's 80,000 times greater than air magnetic permeability

Acts like an electron microscope to magnify and reveal the subtlest detail of the human voice

Extremely low noise

Passes phantom power

Electromagnetically dissipates low frequencies, pop noise, damps mic membrane protecting ribbon mics

Useful for picking up the direct sound only and discriminate against ambient noise, reverberation
