introduction
This kit is used to perform the input attenuation and amplification gain for the AM 16
series preamps of the Langevin brand.
This card is providing the attenuation of the input signal, allowing the various
microphones or line level devices to be adapted to the input sensitivity of the
preamplifier.
A high-quality 6-position switch allows you to choose the preamp gain.
Gain scale is:
0dB, +10dB, +25dB, +35dB, +40dB +45dB.
