Sampled Console Information

Each channel-strip consist of a very simple, single ended class A amplifier block for the mic preamp, with equalization in the feedback path. The input and output are both transformer isolated. These are the modules that Manley based their new production Manley/Langevin Dual Mono preamp upon. I’d suggest googling “Langevin AM4” to find some interesting information.

The eq is 2 bands, high and low, each band with 3 selectable frequencies. The boost/cut controls are stepped, and have a peaking response in boost settings and a shelving response in the cuts. This eq’s simplicity and broad bandwidths give it a very smooth, natural sound. What it lacks in options it easily makes up for in sweetness. Very nice sounding eq.

The amplifier has 4 selectable pad positions, 20 dB each, for up to 60 dB of pad prior to the input transformer. As a result this can accept both mic and line levels through the same single input. I’ve included separate “Line” and “Mic” Level captures. These inputs are essentially identical, except that the character/response is different do to the input level settings.
