How to make almost any microphone sound quite amazing


By using the mic quite close, not nessasarily very close, for example 2in-8in and then connecting at the output a Pleiades (R,L) filter.


This is just an inductor (to create high pass) in series with a resistor (to make the high pass gentle slope). The total can be inside a Neutrik female to male XLR module adaptor.


Resistance, Inductance can be chosen for flat frequency response from producer's brain to listener's brain.


Typical values might be 140Ω, 40mH etc and they depend on the type of song and microoihne output impedance etc.


A step up transformer such as Western Electric 1:2 can further improve by bringing the sound forward like a zoom lens.


Examples:


Male singing voice - Sony ECM-250 - Pleiades (130Ω, 40mH) filter - WE 1:2 transformer - Sony TC-D5 Pro as preamp - Sennheiser HD 580


Or


Male singing voice - Sony TC-D5 Pro - WE 1:2 transformer - Pleiades (130Ω,40mH) - Sony TC-D5 Pro as preamp - Sennheiser HD 580


Mic can be a printed ribbon such as the amazing Fostex M88RP, a ribbon mic,


Or an omnidirectional moving coil such as the amazing Beyerdynamic M119


A directional moving coil..
etc


For even less noise a Pleiades V6 battery powered electron tube booster amplifier can be used as front end to mic. The Pleiades filter should possibly be connected just after the mic.


How does it sound without a Pleiades (R,L) filter?
Confused, bass heavy, mid or mid bass heavy, unfocused.


How does it sound with a Pleiades (R,L) filter?
Focused, big, clear, detailed, in front.. as the brain is relaxed by a more correct sound.
