Filter_settings
All 384 channels are full-band. There is no bandsplitter which splits the signal in an AP and LFP band.
1.0 probes split the recorded data into two two bands: AP and LFP. The data is band pass filtered at 300Hz to 10 000Hz to give the AP band, and this band is sampled at 30 kHz. The LFP band is band passed at 0.5 to 500 Hz, and sampled at 2.5 kHz.
Phase3A probes (which version do I have?).
The LFP band filter is 300Hz low-pass. The AP band filter is high-pass but can be set to 300, 500, or 1000Hz. A typical setting is 300Hz. In both cases, the filters are first order, meaning they are not very sharp, meaning you will see some LFP signals in the AP band and some spiking signals in the LFP band. This is normal. You should consider further filtering your AP band further before processing to remove more low frequency information.
