Low Mid Band
The Low Mid Band is of bell type with the following
center frequencies: 2 kHz, 1 kHz, 500 Hz and 250 Hz.
Low Shelving Band
The frequency options for the Low Shelving Band are
150 Hz, 100 Hz, 80 Hz and 50 Hz.
Low Pass and High Pass Filters
The Low Pass and High Pass filters are controlled by three buttons
respectively, which sets the cut-off frequency for the filters – 15 KHz,
12 kHz and 9 kHz for the
Low Pass and 100 Hz, 50 Hz and 25 Hz for the
High Pass . The cut-off characteristic is unusual and not exactly coherent
but the slope is about 12 dB per octave.
The three settings work independently and can be used in any combination
which means that the more buttons you engage, the more attenuation you get.
For example, pressing all three
Low Pass buttons will actually result in a filter
with an even lower cut-off frequency than 9 kHz.
