VM900 904BCA Filter

The 904A and 904B modules are emulations of the classic transistor ladder-style low pass and high pass filters, respectively. There are three separate modules: 904A is the classic 24dB/oct, low pass filter, 904B is a 24dB/oct high pass filter, and the 904C Filter Coupler allows 904A and 904B to be combined for band reject and band pass responses.
