When the Ping function is turned on, you can verify

which of the components is currently selected by pressing

the DISPLAY button on the receiver. An indication

momentarily appears in the display of the currently

selected component. The indication varies depending on

the component. For example, if the selected component is

either the CDP-LSA1 or the MDS-LSA1,

“N N n n” appears in the display of the

component. Note that this function works on Sony

i.LINK MD deck and CD player only.

1

Improving the quality of the audio signal

(H.A.T.S. function)

When the H.A.T.S. function is turned on, digital audio

signals are momentarily stored in a buffer prior to output.

This reduces the jitter that sometimes occurs during

digital transmission. When this function is turned on, the

H.A.T.S. indicator on the front panel lights up whenever

the digital audio signal is input to the receiver.

1

Press JOG MENU repeatedly until

“Setup Menu”

appears in the display.

2

Rotate the jog dial until

“H.A.T

.S.” appears in the

display, and then press ENTER.

3

Rotate the jog dial until

“On” appears in the

display, and then press ENTER.

To turn off the H.A.T.S. function

Do the procedure above, selecting

“Of

f” in step 3.

Notes

• Due to the operating principle of the H.A.T.S. function, a slight

time lag is introduced between the initiation of an operation

(e.g., pressing the play button, stop button, or pause button)

and the actual audio output.

• The H.A.T.S. function is effective only for the components

supporting this function.

• On this receiver, the H.A.T.S. function works only with digital

audio signals with a sampling frequency of 44.1 kHz.

• The H.A.T.S. function does not work when the program source

component selected by the receiver is also selected by another

component (e.g., another receiver or the MD deck). This is

because the receiver controls the transmission rate of the digital

audio signals output from the program source component, and

for proper signal transmission, there must be only one

component which receives audio signal from a source

component within the i.LINK configuration.

• The H.A.T.S. function doesn

’t work under the following

conditions:

— When the MD is recording from the CD player, and the CD

player or the MD deck is selected as the program source.

— When the sampling frequency of the digital signal is not 44.1

kHz.

About i.LINK

This section explains the general specifications and major

features of i.LINK. Read this section before doing any

i.LINK-related operation.

Note that i.LINK connections and operations may vary,

depending on the component. For details regarding the

connection of i.LINK components to this unit, see

“Audio

Component Hookups

” on page 6.

i.LINK functions

i.LINK is a serial digital interface that supports the

bidirectional transmission of audio and video signals,

commands, and even component status information. All

that is needed to hook up i.LINK components with i.LINK

connecting cables. Audio and video components

connected within an i.LINK configuration can be used to

perform a wide range of operations and data exchanges

that is sure to expand as the number and variety of i.LINK

components grows.

Since i.LINK allows data to be transmitted from one

component to other components to which it is not directly

connected, there is no need to pay attention to connection

order. However, due to differences in characteristics or

specifications, operation of or data exchange with certain

i.LINK components may not be possible, even when they

are connected.

z

What is i.LINK?

i.LINK is a trademark proposed by Sony Corporation and

accepted by companies throughout the world as an easy-to-

remember name for the IEEE 1394 world standard of the Institute

of Electrical and Electronics Engineers.

i.LINK connections

The use of i.LINK connecting cables to connect i.LINK

components as shown below is called a

“daisy chain”

configuration.

i.LINK connecting cable

Data can be transmitted between any two

components even if they are indirectly connected.

Branch connections

• Any i.LINK component with three or more i.LINK

connectors can serve as a branch point.

• Up to 63 i.LINK components can be connected in a

single configuration. However, the maximum number

of components that can be daisy-chained in a single

route is 17 (i.e., a maximum of 16 i.LINK connecting

cables in a row). Each i.LINK cable used in a single

route is called a “hop.” For example, ther

e are six hops

in the route between A and C in the illustration below,

and three hops in the route between A and D.

BA

DC

Each route between A and B; A and C; A and D; B and C; B

and D; and C and D in the illustration above can have 16

hops (i.e., 17 components).

Loop-connection

A signal output from one component is transmitted to all

other components. A loop connection should thus be

avoided to prevent the return of a signal to its source.

Other Operations

Notes

• Some i.LINK components (such as personal computers) don

’t

transfer signals when they are turned off. Refer to the

operation manual of each component to be connected before

you hook them up.

• The maximum transmission rate of an i.LINK component is

printed near its i.LINK connector. The indications S100, S200,

and S400 refer to maximum transmission rates of 100, 200, or

400 Mbps*, respectively. The actual transmission rate may be

faster or slower, depending on the differences in transmission

rates and specifications among the connected components.

z

What is Mbps?

“Mbps” is an abbreviation for megabits per second. It indicates

the amount of data transmitted per second. For example, a rate

of 200 Mbps means 200 megabits of data are transmitted in one

second.

Establishing a LINC

Before an audio signal can be transmitted between i.LINK

components, a “LINC” must first be established between

the receiving component (of the audio signal) and the

sending component. Establishing a

“LINC” means

establishing a logical path for the transmission of digital

audio signals between the two components. Each logical

path has an ID number. Since the component that sends

an audio signal must output the signal to a path, and the

component that receives the signal must input it from the

same path, the path must be mutually known by both

components. During the establishment of a LINC, the

following communication occurs between the two i.LINK

components.

Example

A component establishing a LINC with a CD player in

order to receive an audio signal from the CD player

1 The component that will receive an audio signal

from the CD player sends a request and path

information to the CD player to establish a

transmission path for the audio signal.

1

,

2

<

2 The CD player responds to the component, agreeing

to the establishment of a LINC.

The digital audio signal transmission becomes possible

only after the communication described above has

occurred and a LINC has been established.
