Connectable iPod/iPhone models

The following are the iPod/iPhone models con­nectable to the HP-P1 (as of January 2011 ).

<Note>:The “connectable models” means the
models that can transfer digital audio signal
to the HP-P1 via the Dock Connector to USB
cable.

iPod touch
(the second, third and fourth generations)
iPod classic
iPod nano
(the fourth, fth and sixth generations)

• For the latest information for connectable
iPod/iPhone models, see the Fostex website.

• If your iPod/iPhone is not listed above, see
“Connecting an old iPod/iPhone” described
below.

Connect the USB (type A) port of the HP-P1 to your
iPod/iPhone using the supplied Dock Connector to
USB cable.

<Memo>:

• When the HP-P1 is turned on, the headphone
jac k of the conn ected iPod/iP hone is dis­abled.

• When the ana log input jack is plugged in,
the iPod/iPhone signal is not output from the
HP-P1 (the analog input signal takes priority

over the iPod/iPhone signal).

Connecting an old iPod/iPhone

Some iPod/iPhone does not recognize the HP-P1
when it is connected to the HP-P1 using the sup­plied Dock Connector to USB cable.
In such a c ase , the disp lay of the iPod/iPhone
shows the following message.

The.currently.attached.

accessory.is.not.supported.

by.this.iPod

In this case, the iPod/iPhone audio signal cannot
be sent to the HP-P1 via the Dock Connector to
USB cable.
To send the iPod/iPhone audio signal to the HP-P1,
two methods are available.

(1) Connect the headphone output jack of the iPod/
iPhone to the analog input jack of the HP-P1.

When the HP-P1 is connected to your iPod/iPhone
and the iPod/iPhone recognizes the HP-P1, the dis­play of the iPod/iPhone can show the HP-P1 infor­mation as below.

Version...XXXXX

<Note>:If the display of your iPod/iPhone does
not show the HP-P1 information as above, see
“Connecting an old iPod/iPhone” described be­low.

(2) Connect the Dock connector of the iPod/iPhone
to analog input jack of the HP-P1 using a “Dock
connector to mini phone plug” cable available in
the market.

• With method (1) above, the iPod/iPhone digital
signal is sent to the HP-P1 via the iPod/iPhone
headphone amplier. On the other hand, with meth­od (2), the iPod/iPhone digital signal is directly sent
to the HP-P1 (the iPod/iPhone headphone amplier
is bypassed).

By connecting an audio device that provides the
analog line output to the analog input jack of the
HP-P1, you can monitor high quality audio sound
via headphones.

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 amplier to ei­ther of these jacks, you can copy iPod/iPhone au­dio sources or monitor them from a speaker system
with ne audio quality.

<Memo>:When both the analog input jack and
USB c onnecto r (type A) are plug ged in, the
signal from the analog input jack takes priority
over the iPod/iPhone signal (the iPod/iPhone

signal is not output from the HP-P1).

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 ca n make d ubb ing of iPo d/iPhone
audio sources or monitor iPod/iPhone from your
speaker system with ne audio quality.

Using the [LINE OUT] jack

The [LINE OUT] jack outputs an analog audio sig­nal that is converted from an iPod/iPhone digital
audio signal or that is fed to the analog input jack.
By connecting a recorder or audio amplier to this
jack, you can make audio dubbing of your iPod/
iPhone audio sources or monitor iPod/iPhone from
your speaker system.

<Memo>:You cannot control the output level
of the [LINE OUT] jack using the power switch/
volume control dial.
