i.LINK (IEEE 1394)
The i.LINKconnection is also known as IEEE 1394or "firewire"
an international specification.
This unit is ready for i.LINK (AUDIO).
By connecting an i.LINK (AUDIO)-capable device to the IEEE 1394
(or i.LINK (AUDIO) terminal on this unit using an i.LINK cable, you
can transmit Super Audio CD multi-channel signals. This allows
Super Audio CD muiti-channel information to be transmitted in
its original digital format, in addition to the capability of
transmitting 2-ch linear PCM data and multi-channel compressed
audio signals.
If you have multiple i.LINK-capable devices, you can connect them
through other devices to transmit data between them, In this case
you do not need to be concerned with the order of connection.
Copyright protection system DTCP
To play back audio sounds recorded on Super Audio CD or DVD
discs using i. LINK, the player and the internal D/A converter need
to be compliant with the protection system known as DTCP
(Digital Transmission Content Protection).
This unit is fully compliant with DTCP.
Data transfer rate
There are three transfer rates: 100 Mbps (S100), 200 Mbps
(S200), and 400 Mbps (S400). This unit is capable of transferring
data at a maximu m rate of 400Mbps.
For connection to an i.LINK-capable device, use a commercially
available S400-compliant 6-pin i.LINK cable.
When connecting multiple i.LINK-capable devices, avoid
connecting a device having a slow transfer rate between
devices having high transfer rates since this reduces the
transfer rate of the entire system.
Connect devices having high transfer rate towards the source
as far "up-stream" as possible.
NOTES
<Among the i.LINK formats there are “MPEG-2 TS” for BS
digital sources and “DV” for digital video for DVD recorders,
as well as the “i.LINK (AUDIO)” (A&M Protocol). Never
connect devices that are not ready for i.LINK (AUDIO) to this
unit. If you do, this unit and others may become out of order or
become damaged.
<While in the process of data transfer, avoid plugging/unplugging the
i.LINK cables while in use or switching the power control on or off.
<Among i.LINK-capable devices there are some that if not
turned on, are not capable of relaying data.
<Some i.LINK-capable devices may not respond to this
unit's command.
How to connect multiple i.LINK-capable
devices
Daisy chain connection
You can daisy-chain up to 17 devices including this unit.
Connection in tree structure
If you are using a device having three or more i.LINK connectors,
you may want t ohavethe connection branched out. This way of
connection allows you to connect up to 17 devices including this
unit.
Your system will not work if data is fed back to the output
device. Therefore, be careful not to create an iLink signal loop.

The i.LINK interface of this unit is designed in accordance with
the following specications:
1) IEEE Std 1394a-2000, Standard for a High Performance
Serial Bus
2) Audio and Music Data Transmission Protocol 2.0
This unit is compliant with IEC 60958 bit stream, DVD-Audio,
and Super Audio CD in the AM824 sequence adaptation
layers of this protocol.
Flow rate control
This unit supports i.LINK ow rate control. Flow rate control
means that audio data transferred via i.LINK is rst stored in
RAM inside this unit after which the high-precision clock within
the unit is used to move the data from RAM to avoid, the
transfer jitter normally associated with i.LINK transfer.
This unit transfers commands to the playback device to
change the data transfer rate and controls the playback device
when data accumulated in RAM exceeds or goes below a
certain rate due to differences in clock frequencies in the
playback device and this unit. Flow rate control functions in
transfers between this unit and other units within the chain.
