i.LINK (IEEE1394)

i.LINK is an international specification also known as IEEE 1394.
This unit supports i.LINK (AUDIO).
By connecting an i.LINK (AUDIO)-capable device to the i.LINK (AUDIO)
connector on this unit using an i.LINK cable, the unit can transmit
2-channel linear PCM signals and multi-channel compressed audio
signals as well as digital Super Audio CD multi-channel signals as is.
When connecting multiple devices that support i.LINK, you can trans-
mit data between any two devices even when they are connected
indirectly through other devices. You do not need to worry about the
connection order unless they have different data transfer rates (see
below).

DTCP copyright protection system

To play back Super Audio CD audio using i.LINK, both the player and
the D/A converter need to support the Digital Transmission Content
Protection (DTCP) copyright protection system.
This unit supports DTCP.

Data transfer rate

This unit's maximum data transfer rate is 400 Mbps (S400).
Use commercially-available i.LINK cables that support S400 to make
connections.

When connecting multiple devices, putting a device with a slower
transfer rate between devices with higher transfer rates will slow their
data transfer rates. Connect devices with the same transfer rates as
close together as possible.

Flow rate control

This unit supports i.LINK flow rate control. Flow rate control is a trans-
mission technology that eliminates jitter that occurs during i.LINK
transfer. The audio data transferred via the i.LINK input is first stored
in this unit's RAM, and then the unit's high-precision clock is used to
transfer the data from RAM. If the data stored in the RAM becomes
more or less than a certain amount due to clock frequency differ-
ences between the playback device and this unit, this unit controls
the playback device and sends commands to the playback device
to change the data transfer rate. Flow rate control functions during
direct transfers between this unit and the player.

CAUTION

o

In addition to the “i.LINK (AUDIO)” (A&M Protocol) used by this unit,
other i.LINK transfer formats include “MPEG-2 TS” used by BS digital
broadcasts, for example, and “DV” used for DVD recorders and digi-
tal video. Never connect computer peripherals or other devices
that do not support i.LINK (AUDIO) to this unit. Doing so could
cause malfunction or damage.

o

During data transfer, avoid connecting or disconnecting i.LINK
cables with connected devices or turning them on or off.

o

Among i.LINK-capable devices, some will only transfer data when
on.

o

Some i.LINK-capable devices might not function properly with this
unit.

o

The receiving device might not support this unit's output mode.
You should also carefully read the operation manuals of all the
connected devices.
