Simplex Vintage Compressor Mic Pre |
|
The Simplex Vintage Compressor is a high quality microphone and instrument octal tube compressor preamp with pure and transparent triple gain stage class A design
featuring Input and Output transformers handwound by Jensen.
The Compressor/Sustainer/Limiter in class A has even-order musical harmonics enhanced by Germanium Diodes with asymmetrical clipping.
Providing a natural sound experience with a relaxed, warm and sweet sound stage
delivered by the lively responsive and wide frequency range of Octal Tubes.
A microphone preamp is arguably the most important sound generating device in any recording setup.
It comes right after the weak signal from a microphone or instrument pickup and boosts it to recording line level.
Without a fine quality preamp, music and sound quality is lost right in the beginning of a recording signal chain
and even excellent effects and mixing consoles can't recover and infuse the sound with it's original pure quality.
The Octal Tubes in the Simplex Vintage enhance that quality with their unique, lively and musical character.
