Using the menu
The menu is controlled by 3 buttons:
•
The
Menu
button opens the menu and with the menu open acts as the
Select
button.
•
The
Step Forward
button pages forward through the menu.
•
The
Step Back
button pages backward through the menu.
•
The
Power
button closes the menu.
When the
Menu
button is pressed, the button lighting switches off, except the
Menu
button itself, and
the two buttons that drive the menu.
You can also use the
Rotary control
to page backwards and forwards through the menu. Successive
presses of the
Step Forward
or
Step Back
button page through the menu. You cannot go directly to
any particular page.
There are three ways to close the menu:
•
You can use either
Step
button until the display shows
Exit
and then press
Select
.
•
5 seconds after your last command the menu will time-out and the
P8i
will revert to normal
operation.
•
Press
the
Power
button briefly.
Menu Sequence
The following explanation briefly deals with the Menu pages in the sequence they occur in the Menu,
and this summarised in the Control Summary.
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 2
.
Filter 4
is intended for troubleshooting, not listening – it has a very low level of out-of-band noise
and a 20kHz bandwidth.
Selecting the best filter for your system is simply a matter of cycling through Filters 1, 2 and 3 as you
play a disc and choosing the one that you think sounds best. The best choice will depend on your
system, the tonal qualities of the music and your taste.
To choose a filter press the
Menu
button and cycle through the menu with the
Step Back
or
Step
Forward
button until
Filter
is displayed. Now press the
Select
button repeatedly to scroll through the
different filter options.
Phase
This option allows you to invert (reverse the phase of) both channels to correct a phase error in the
source data.
Layer (CD, SACD)
While playing a hybrid disc, the SACD layer is played by default. The
Layer
page allows you to select
either the
CD
or
SACD
layer. While changing layers and re-reading the disc,
Loading...
is displayed.
