CH (Channel)

When the i.LINK (AUDIO) terminal is connected to a digital
device, select the channels for this unit.
The factory setting is L/R.

L/R: front left and right channels
C/LFE: center channel and LFE (subwoofer)
LS/RS: surround left and right channels

<

The icons of the selected channels light on the display.

i_RC (i.LINK remote control function)

When multiple AI-10 units are directly connected using i.LINK
cables and you use this function, the volume, muting and
dimmer of all AI-10’s in the chain can be controlled using only
one AI-10.

Since this function is available as long as AI-10’s are
connected using i.LINK cables, you can use a different input
type other than i.LINK.

ON

The volume, muting and dimmer of all AI-10’s in the chain
can be controlled using the L/R channel AI-10.

MASTR
SLAVE

When you set one AI-10 as master and all other AI-10’s as
slaves, the volume, muting and dimmer of all AI-10’s in the
chain can be controlled using only the master unit.
This master-slave control has nothing to do with the channel
setting.

OFF (factory setting)

Select this setting position when the i.LINK remote control is
not used. The volume, muting and dimmer of all AI-10’s in
the chain cannot be controlled as a whole.
The i.LINK circuit is powered only when the input is set to
i.LINK.

Note

When two AI-10’s are connected using i.LINK cables and one
AI-10 is connected to the front left speaker and the other AI­10 is connected to the front right speaker as shown below,
one AI-10 can be used as an amplifier dedicated to the left
channel and the other as an amplifier dedicated to the right
channel.

The MASTR and SLAVE settings of the i.LINK remote control
function allow you to set one AI-10 as master and the other as
slave, so that the volume, muting and dimmer of the two AI­10’s can be controlled in unison using one of the pair units.

i.LINK (IEEE 1394)

Flow rate control

This unit supports i.LINK flow rate control. Flow rate control
means that audio data transferred via i.LINK is first stored in
RAM of this unit after which the high-precision clock in the unit
is used to retrieve 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 control the playback device when data accumulated in
RAM exceeds or goes below a certain amount due to differences
in clock frequencies in the playback device and this unit. Flow
rate control functions in transfers between this unit and another
unit.

The i.LINK (AUDIO) terminals will become available after a
future hardware upgrade (charged).

The i.LINK is also known as IEEE 1394, an international
specification.
By connecting an i.LINK (AUDIO)-capable device to the i.LINK
(AUDIO) terminal on this unit using an i.LINK cable, you can
transmit Super Audio CD multi-channel signals that could not be
transmitted but in analog format in the past can be transmitted
in its original digital format, in addition to the capability of
transmitting 2-ch linear PCM data.
If you have multiple i.LINK-capable devices, you can connect
them through other devices to transmit data between them, so
you don’t need to be concerned with the order of connection.

Copyright protection system DTCP

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

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 maximum 400Mbps.

For connection to an i.LINK-capable device, use a commercially
available S400-compliant i.LINK cable (6-pin or 4-pin).

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 whole system. Connect devices having high transfer rates
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 compatible with i.LINK (AUDIO)
to this unit. If you do, this unit and other components may
not operate normally and may also become damaged.

<

In the process of data transfer, avoid plugging/unplugging the
i.LINK cables in use or switch on/off the power.

< Among i.LINK-capable devices, there are some that, if not

turned on, are not capable of relaying data.

< Some i.LINK-capable devices will not respond to this unit's

command. This is normal and is due to incompatibility among
i.LINK devices.

<

The receiving device may not support the output modes of
this unit. Read through the instruction manual of devices you
want to connect before making any connections.

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 to branch out the connections. This way of
connection allows you to connect up to 17 devices including this
unit.

Your system does not work if data is fed back to the output
device. Be careful not to create a loop.

OPTICAL or COAXIAL terminals. Use analog audio terminals
(LINE IN).

No digital audio output.

e

The AI-10 isn’t equipped with Dolby Digital/DTS/MPEG
decoders. The digital output setting of the connected player
must be PCM. Or use analog audio terminals (LINE IN).

Unstable sound.

e

Speaker polarity (+/_) is reversed. Check all speakers for
correct polarity.

Word Sync

The display shows “WRD ERROR!”

e

The connected unit may not be in word sync mode while
the AI-10 is in word sync mode. Check the word sync
terminal for correct connection and the settings on the
connected unit.

e

The received digital signal doesn’t much the sync signal.
Check the frequency of the word sync signal (see page 16).

e

When you don’t use the WORD SYNC terminal, turn the
word sync mode off (see page 13).

Buzzing noise produced at regular intervals.

e

The connected unit may not be in word sync mode while
the AI-10 is in word sync mode. Check the word sync
terminal for correct connection and the settings on the
connected unit.
Normally, if this problem occurs, the display reads “WRD
ERROR!”, but this message does not appear when deviation
in sync is too small and out of the word error detection
threshold of the AI-10.

i.LINK (AUDIO) terminal

The i.LINK (AUDIO) terminals will become available after a future
hardware upgrade (charged).

No i.LINK output.

e

Check the channel setting. One AI-10 unit must be set to
L/R channel when multiple AI-10 units are connected.

The i.LINK indicator blinks.

e

Turn on the digital device connected to the i.LINK(AUDIO)
terminal. When you don’t use the i.LINK terminal, turn the
i_RC setting off.

If normal operation cannot be obtained, unplug the power
cord from the outlet and plug it again. This resets the
internal micro-computer which can be disturbed during
electrical storms, power interruptions, et cetera.

Short Circuit and Output Protection

“OVER LEVEL” blinks on the display when the short circuit
protection (or the output protection) is activated. In this case,
turn the unit off and check the speaker cables. The metal
portions of the two separate wires should not touch.
If there is no shorted wire, turn down the volume using the
VOLUME knob.
