About i.LINK

i.LINK is a trademark name for IEEE1394, a high-speed
interface for digital audio, video and other data found on
personal computers, digital camcorders, and other kinds
of audio and audio/visual equipment. A single i.LINK
connector can both send and receive data at the same
time, so only one cable is required to connect compo-
nents for two-way communication.

About PQLS rate control

Pioneer's PQLS (Precision Quartz Lock System)
technology provides high-precision digital audio from
DVD-A, SACD and audio CD sources when you use the
i.LINK interface. A precision quartz controller in this
receiver eliminates distortion caused by timing errors
(jitter), giving you the best possible digital-to-analog
conversion from the digital source.
To take advantage of PQLS, you must have a player
compatible with rate-control, and it must be switched on
and connected to this receiver through the i.LINK

Creating an i.LINK network

Using i.LINK it is possible to chain up to 17 components
together so that the digital audio and control signals
from each component is available to other components
in the network. With the addition of an i.LINK repeater,
it’s possible to connect up to 34 components.
i.LINK connectors come in 4-pin and 6-pin configura-
tions. This player uses the 4-pin connection, but the two
types can be mixed on a network.
This receiver is compatible with i.LINK Audio (A&M
protocol) components, such as DVD players. Note that
when connected to i.LINK MPEG-II TS equipment (such
as a digital satellite tuner), i.LINK DV equipment (such as
a DVD recorder or DV camcorder), or an i.LINK-equipped
personal computer, audio and video signals are not
transmitted, and connecting to these devices sometimes
causes network interruptions. Check the operating
instructions supplied with your other i.LINK components
for compatibility information.
This receiver is DTCP (Digital Transmission Content
Protection) compliant, so you can play DVD-A, DVD-
Video, and SACD i.LINK audio.
When setting up an i.LINK network, it’s important that
the components form an open ended chain (fig. 1), or a
tree (fig. 2).
The system will not work if the connected components
form a loop. If a loop is detected, the message
shows in the display. Figs. 3 and 4 show
connections that form a loop.
Another consideration when connecting i.LINK devices
is the speed of the interface. At present there are three
speeds; S100 (slowest), S200 and S400 (fastest). This
receiver uses the S400 type. Although you can use
components with different speeds together, we
recommend connecting slower-speed components at
the edge of the network if possible (shown by the shaded
boxes in figs. 1 and 2). This will keep the network free of
When used within an i.LINK network, this receiver must
be on for the i.LINK connection to be maintained. Other
components in the network may or may not maintain the
connection in standby (none will when the power is
completely off)—check the operating instructions
supplied with individual components. Note that the audio
may be momentarily interrupted if a component in the
i.LINK network is switched on/off, or its i.LINK
connection is switched on/off.
This product complies with the following i.LINK interface
1) IEEE Std. 1394a-2000, Standard for a High Performance
Serial Bus
2) Audio and Music Data Transmission Protocol 2.0
Following the standard for AM824 sequence adaptation
layers, the product is compatible with IEC60958 bitstream,
