Pleiades microphone impedance matching transformer using Magnetec's Nanoperm revolutionary extremely high inductance index nanocrystalline tape wound core toroid.
Designed to remove unwanted bass increase due to the proximity effect. Suitable for distance of even less than 1in! Can be used at any unbalanced high impedance mic input such as Tascam's Porta.
Provides balanced impedance matching of 50-200 ohms microphones such as the the Shure SM-58, Sennheiser MD421, Coles 4038 or Reslo ribbon mics to the usual 10K-50K ohms input impedance, (max power transfer), no reflection of energy. The turn ratio is 1:7, increasing impedance 49 times. Reserving right to make revision changes, item may not look exactly the same, handling time 30 days. Other step-up ratios may be ordered.
Electromagnetic damping of pop noise, protection of the membrane or ribbon at any distance. You can try the principle by short circuiting any speaker driver unit with a cable and tapping the membrane with your finger.
Extremely low noise.
Diamond sparkling quality for studio production work.
The subtlest detail revealed with nanoperm's permeability of the order of x100,000!
