L-1 Filters. First impressions. 24dB LP mode.
video upload by Aleksei Laman
"L-1 filters collection.
First impression on new L-1 filters. Now only 24dB LP mode, single saw wave input.
All filters are built from identical blocks but with different architectures (topologies). Building blocks are: L-1 original Discrete Blacksea gain cells (VCAs), and silver-mica capacitors (best capacitors for filters).
Filters:
DD VCF - Discrete Dual. Two 12dB State-Variable filters in series give 24dB/oct filtration.
DM VCF - Discrete Mulimode. Using double gain cells in State-Variable topology it gives 24dB/oct filtration.
DP VCF - Discrete Pole. Four poles filter gives 6, 12, 18, 24 dB LP outputs. Mixing the outputs it gives BP, HP, N (notch), DN (double notch) filtration.
DS VCF - Discrete Sallen-Key. Switching system (12 electronic switches used) switches between LP, BP and HP topologies.
