Preamplifier

Preamp format 500 ultra quiet with very little background noise, heat and absolute wealth. The PowerPre is the tool that makes it easier excellent audio. Composed of 100% of discrete circuits. The Powerpre AccuState uses the technology to adapt the signal to noise ratio for all staff levels.

Radial PowerPre is a high quality preamp module adapted to be housed in the BBH. Composed of 100% of discrete circuits, it delivers not less than 70db max gain.
The output stage employs a transformer for more roundness and richness.
The front face is provided with a XLR jack for the microphone input, as well as an embedded mini switch 48V, for even greater security for the use with a microphone, tape for example.
In contrast to most market preamps, which require an adjustment to the specific input gain, to prevent unwanted background noise, the Powerpre AccuState uses the technology to adapt the signal to noise ratio at all employee levels.
A meter shows ten segments so highly precise levels of the input stage to refine every shot.
