Menu Sequence

The following explanation briefly deals with the Menu pages in the sequence they occur in the Menu,

Filter

While upsampling a CD or playing an SACD, the P8i offers a choice of 4 filters. The filters offer
different trade-offs between signal bandwidth and out-of-band noise level (which is inherent in the 1-bit
nature of DSD).
Filter 1 is the usual setting, giving the widest bandwidth (about 70kHz) with the highest level of out-
of-band noise.
Filter 2 gives a slightly narrower bandwidth with a lower level of out-of-band noise.
Filter 3 gives a slightly narrower bandwidth again and less out-of-band noise than
Filter 4 is intended for troubleshooting, not listening – it has a very low level of out-of-band noise
and a 20kHz bandwidth.
