Connecting a recorder or audio amplifier
In addition to the headphone output, the HP-P1
also provides the [LINE OUT] jack that feeds the
analog signal as well as the [S/PDIF] output jack
that feeds the S/PDIF digital signal.
By connecting a recorder or audio amplifier to ei-
ther of these jacks, you can copy iPod/iPhone au-
dio sources or monitor them from a speaker system
with fine audio quality.
Using the [S/PDIF] output jack
The [S/PDIF] output jack outputs the S/PDIF digital
signal that is digital-to-digital converted from an
iPod/iPhone digital audio signal received from the
USB connector (type A). By connecting a recorder
or amplifier that provides the digital input to this
jack, you can transfer an iPod/iPhone audio source
in digital domain (without converting it to analog).
That is, you can make dubbing of iPod/iPhone
audio sources or monitor iPod/iPhone from your
speaker system with fine audio quality.
